Linux upgrade all packages

Ubuntu upgrade or update a single package using apt-get

How to Ubuntu upgrade or update a single package

The procedure to update a a specific package on Ubuntu:

1. Open the Terminal application
2. Fetch package index by running sudo apt update command
3. Now only update apache2 package by running sudo apt install apache2 command.
4. If apache2 package already installed it will try to update to the latest version. If you do not want to install new packages; when used in conjunction with install, only-upgrade will install upgrades for already installed packages only and ignore requests to install new packages. Try sudo apt —only-upgrade install apache2

Let us see all commands and examples in details.

How to upgrade a single package using apt-get?

As usual you need to fetch an updated index from the Internet:
$ sudo apt-get update
You need to use following format with the apt-get command/apt command:
$ sudo apt-get —only-upgrade install Package
$ sudo apt-get install Package
Let us try to upgrade nginx web server:
$ sudo apt-get install nginx
If nginx package is already installed it will try to update to latest version:

However, the following will not install a new nginx package if not installed:
$ sudo apt-get —only-upgrade install nginx
In this following example, htop is installed and I am requesting update. However, atop not installed and I am still requesting an update for it:
$ sudo apt-get install htop
$ sudo apt-get —only-upgrade install atop

Examples

First, download package information from all configured source:
$ sudo apt-get update
Run the to see availble updates:
$ sudo apt list —upgradable

Linux Commands To Update All Packages

1. Debian / Ubuntu / Mint Linux and friends try the apt-get command/apt command.
2. CentOS / RHEL / Red Hat / Fedora Linux and friends try yum command.
3. Suse / OpenSUSE Linux use the zypper command. We can also use graphical tool called YaST online update.
4. Slackware Linux user try the slackpkg command.
5. Arch Linux user try the pacman command.
6. Gentoo Linux user try emerge command.
7. Alpine Linux user must use apk command.

update vs upgrade in Linux

We use the update option to download package information from all configured sources such as the Internet. The upgrade option will install available upgrades of all packages currently installed on the system from the sources such as the Internet. New packages will be installed if required to satisfy dependencies, but existing packages will never be removed. If an upgrade for a package requires removing an installed package, the upgrade for this package isn’t performed. Hence, this is a safer option in all cases.

apt-get command example to update all packages on the Debian or Ubuntu Linux

Run:
$ sudo apt-get update
$ sudo apt-get upgrade

How To Update All Packages On Ubuntu

Updating packages in Ubuntu is, to be honest, quite a simple task that can be done with just two mouse clicks, or by typing two commands if you are updating via terminal. There are two major ways that you can go about completing this task. You can update your packages via command line, or if you like to perform tasks using GUI, you can update your packages graphically using Package Updater. The choice is yours to make.

Method 1:Via Terminal

On the Ubuntu desktop, go to the terminal by clicking the terminal icon in the shell or simple press Ctrl+Alt+T.

In the terminal type, the following command

After typing the above command, you will be asked for your password. Type the password in the terminal. No characters will be shown on the terminal when you are writing your password. After typing the password, hit enter.

Now contrary to popular belief, this command doesn’t update your system. Instead, it updates your Ubuntu repositories. So your system checks against the repositories. It checks if there are newer versions available of the program installed. It won’t update your existing packages right away; instead, it will update the information about the existing packages and their versions available. This is the reason that when this command finishes execution, Ubuntu shows you the number of packages that can be updated.

In the picture above, you can see that when this command finishes execution, Ubuntu shows you the list of packages that can be updated. In order to view these packages type the following command

You can update a particular package, or you can update all of the updatable packages on your Ubuntu. To update all your packages, just type the following command in the terminal.

After typing the above command again, Ubuntu will ask you for your password. Like before, type in the password and hit enter.

After 2 or 3 seconds Ubuntu will show you the amount needed to update these packages and will further ask for your confirmation. To continue, type y in the terminal and press enter. Once you do this, Ubuntu will start downloading and updating your packages.

This command will download and update all of the packages that need updating. A little pro tip here to make this updating task easy. You can also type the following command instead of typing in these two commands.

As the two commands require to run in succession, we can combine them into a single command. The && between the two commands combines them. So now the first command before the && sign runs. When the first command has completed execution, the rest of the command after the && is executed. The -y at the end will save you one keystroke where Ubuntu asks you whether you want to install the upgrades or not. You should run this command from time to time to keep your system up to date.

Method 2: Update using Package Updater:

Go to the menu and in the search bar type “Software Updater.”. Now run it.

It will check if there are any packages on your system that can be updated.

If there are any such packages, it will give you the option to install the updates

Click on Install Now. It will ask for your password. Type your password and hit Authenticate.

After authenticating, Ubuntu will start downloading and installing the updates.

In some cases, you might be asked to restart your system after the updates. This is so that the installed, updated packages can take full effect and function properly.

In most of the cases after updating, there are some packages the are of no further use to the user. You can delete them, which will free up your system space and keep your system clean and tidy, which is always a good thing. To do so type the following command in the terminal

This tutorial is valid for all the versions of Ubuntu and other Linux distros based on Ubuntu like Linux Lite, Linux Mint, etc.

Conclusion:

I hope this tutorial will be helpful to you. One of the many things you hear about Ubuntu is that it’s a lot safer than Windows. The proof can be seen when updating. Whenever you make any changes to the system, Ubuntu asks you your password for authentication. Updating packages in Ubuntu is quite simple. Bear in mind that this tutorial is for updating packages in Ubuntu. It doesn’t update your Ubuntu version. Also note that this tutorial, including the command line method, is valid for all the versions of Ubuntu and other Linux distros based on Ubuntu like Linux Lite, Linux Mint, etc.

How Do I Update Ubuntu Linux Software Using Command Line?

I have latest version of Ubuntu Linux LTS server. How do I update Ubuntu Linux for security and application fix/upgrades using ssh command line? How can I install updates via command line option?

Ubuntu Linux can be upgraded using GUI tools or using traditional command line tools such as:

1. apt-get or apt command – apt-get command or apt command is the command-line tool for handling packages.
2. aptitude command – aptitude is a text-based interface to the Debian GNU/Linux package system including Ubuntu Linux.

Update Ubuntu Linux Software Using Command Line

Let us see all commands and options in details.

Ubuntu Linux server – Install updates via apt-get command line ( option #1 )

The commands are as follows:

1. apt-get update : Update is used to resynchronize the package index files from their sources on Ubuntu Linux via the Internet.
2. apt-get upgrade : Upgrade is used to install the newest versions of all packages currently installed on the Ubuntu system.
3. sudo apt-get install package-name : Install is followed by one or more packages desired for installation. If package is already installed it will try to update to latest version.

First, open the Terminal application and type following two commands (Application > Accessories > Terminal and then type the commands as the root user).

Get updated software list for Ubuntu, enter:

Update software(s) i.e. apply updates and patches on Ubuntu Linux

Type the following apt-get command:
$ sudo apt-get upgrade
OR
$ sudo apt upgrade

Installing updates on Ubuntu Linux system

Install kernel updates on a Ubuntu LTS server

Type the following apt-get command:
$ sudo apt-get dist-upgrade
If a new kernel installed, reboot the Linux server:
$ sudo reboot

To upgrade individual software called foo type command:

$ sudo apt-get install foo
OR
$ sudo apt-get install apache php5 mysql-server

Ubuntu Linux server – Install updates via aptitude command line ( option #2 )

The syntax is as follows to Update the packages list:
$ sudo aptitude update
To actually upgrade the packages, type:
$ sudo aptitude safe-upgrade

Apply Ubuntu server updates over ssh based command line session

First, login to the remote Ubuntu server using ssh client:
$ ssh user@server-name-here
$ ssh vivek@server1.cyberciti.biz
Once your log into your server, run the following two commands:
$ sudo apt-get update
$ sudo apt-get upgrade
OR
$ sudo aptitude update
$ sudo aptitude safe-upgrade
OR
$ sudo apt-get update
$ sudo apt-get dist-upgrade
From the apt-get(8) page:

The dist-upgrade in addition to performing the function of upgrade, also intelligently handles changing dependencies with new versions of packages; apt-get has a “smart” conflict resolution system, and it will attempt to upgrade the most important packages at the expense of less important ones if necessary. So, dist-upgrade command may remove some packages. The /etc/apt/sources.list file contains a list of locations from which to retrieve desired package files.

Using Ubuntu Update Manager GUI tool

Ubuntu Update Manage the GUI tool. It works like Microsoft or Red Hat update manager i.e. you will see a little icon in the kicker bar/taskbar when there are updates. It will only appear when new upgrades are available. All you have to do is click on it and follow the online instructions. You can also start the GUI tool by Clicking System > Administration > Update Manager

A note about the latest version of Ubuntu Linux

Press the Superkey (Windows key) > Type updater:

I installed ubuntu sofware in my laptop but I can changed the display of monitor (the evolution of screen is only 1240×768). I want to change it into 1240×800 to fit with the widescreen. So what do I do to change it.
I want to have vietnamese font in ubunto? please let me know the way to get it!
thank you very much!

may i know ur processor plz

I installed the ubuntu 7.10 versiyon.At the beginning ı can not connect the internet then find a way and mozilla can connect the web.But there is a problem about updates ı have not a web connection for doing updates.no problem about modem no problem about networking and mozilla work good but other application like pidgin and updates do not connect web.What can ı do?

Try updating your software sources. Go to linux ubuntu website and search for software sources. I had this problem similar to this with my Pidgen. I had to change the server addresses for my Yahoo chat to work. But you go to System>Administration>Software Sources. Hope This Helps You….

I cannot update my Feisty 7.04 and don’t have GUI on the server!
How can I do any updates at all?
apt-get update returns a lot of errors but downloads some things? I do not know what or where?
and apt-get install update does Not work and gives me E: error !
I know now that ubuntu has abandoned the 7.04 version and has changed the link/ulr so the server cant find the files it needs (to download). but when I try to put a correct link in my sources.list file the errors continue!?
Does anyone know how to Manually install the updates.
Now if Microsoft had change the URL, we would never hear the end of it, that is only fair not to mess with the configuration files on a fairly new operating system (feisty 7.04 is not that old at all, compared to NT is a new born baby)!
I am new in linux and really like some of the features but it sucks when you have to spend all your time on a dumb little simple matter as to an update,

Working Ubuntu server from the command-line, this help was very useful.

I the speed of updating is so slowly,what should i do to update faster?

yes…..it was last updated for 113 days ago….fuck the update manager……check,check,check

if you update your network settings and if you are getting IP address from DHCP you can run dhclient eth0 (or whatever NIC) and update the net info.
this will improve your speed.

Hello,
I installed ubuntu linux 9.0 on my computer how can i install a program i bought from the store or add a new graphics card. I have been trying to put new programs on my computer but the disc always comes up as a file and doesn’t autorun the program for installation. need much help thank you

If you are in the Graphical mode (GUI) then you can browse the cdrom to see what program is executable (usually install.sh or similar program).
If the CD is a linux program then a shortcut (link) to it will appear on your desktop.

If you are in the command line;
There are usually a link (or shortcut) to the CDROM in the root of your drive, if there isnt then you have to cd /media then cd cdrom .
if you have the rights (login as root or type su ) then you can cd /cdrom
(after you load the cd in the drive) then you can do an ls to see any install.sh program or README file to tell you how to install that program.

Great stuff, but can you upgrade just a single package eg. phpmyadmin only?

Very good if you have a working system! But mine is not working so I can’t up date cos my upgrade is not completed until the desktop is updated and running.

So do I just re-load again or have I misses some thing?

How can you install a windows program on ubuntu?

firstly you must install wine. after you can install windows program together wine.

I am not an expert in Linux but I think you have to use the fdisk program in linux to create an NTFS or FAT32 partition so you can install Windows on it.
fdisk in command prompt is easy to use really,
you can do an fdisk -l (L) to see what is available then do fdisk /dev/sda1 or whatever
press m for help. then l to see the list of partitions. (i.e 8e for LVM or virtual drives in Linux)…

OR if you already have an unused partition (empty) you can install Windows on it.
but take extra care not to format the linux partition.

IF your Linux system does not come up correctly you can type fsck to fix it.

There may be a suitable alternative to your Windows program, depending on what it is. There are lots of choices as far as open source software goes, you might get lucky.

You might also be able to use Wine, a Windows Emulator to install and run your Windows program, again, depending on what program it is.

Hello all….
It’s been great with the Karmic. I’m using it almost anywhere. And it does work like charm after install.. And right now i’m learning the command so i can setup my own server box. Mehdi, you are a great guy, always trying to help others… So i want to add a bit on what mehdi talk about.
If u want to run a windows program install WINE and then you can run a lot of windows program(not all.. go to winehq and read the list)
I can run my warcraft & Counter Strike that reside on my NTFS(windows) partition just like that. WINE is really a great program.
2. U don’t need fdisk all the way to manage a partition. Use gParted instead. Shrink the partition. make a new empty partition and boot up the windows cd and install windows. then configure the GRUB loader to boot your windows as well.
3. Always make time to read some tutorial and browse the forum. It will help you greatly. And try to always use the terminal to make you more understand linux (although ubuntu have done a well done job on the GUI side)

after installing packages how can i see the list of the packages or files that were just install? I am talking use terminal commands?

I HAVE problem to activate ubuntu 10.6 in my compture.

I’ve faced a problem in using ubuntu to update softweres of midia player ,video player,to running & to compile fortran programming language & more help me

I am very new to ubuntu linux, I was wondering, if I have Ubuntu and I want to upgrade it to the next version, will the drivers (and etc), get updated (or at least stay there) as well? Or do I need to install one and each of them again manually?

I am new and still learning but here’s what I know:
If you have a computer which is running Windows then I suggest to use the Wubi which is a small file but installs the latest version of Ubuntu for you (without making changes in your file allocation table or boot sector and you will Not lose any of your Windows files, and it defaults into Windows with Ubuntu as 2nd choice).
As for the updates and upgrades Ubuntu has a program which comes up automatically and asks you to verify username/password and then it updates it regularly (You can turn that option off or set it in longer intervals), Otherwise you can do it in terminal by sudo apt-get updates or upgrade.
I had a bit of problem with the Auto Updates (In GUI) with version 10.x, I have not had any trouble with (the auto-updates) in this new (11.x ) version so far and I have been using it for few weeks now.
In the last version it would totally freeze the computer and the last time it froze I lost everything (of course it was a learning machine and I didnt rely on it for anything) But then other people told me they had same problem (in version 10.x).
So to be on the safe side, try to use the command line for updates and upgrades.

Also I think with updates you update the lib. files and some drivers but with upgrade you upgrade the kernel file?!
good luck.

I am having troubles updating my 7.04 Feisty. I am trying to update to 11.04, but am not successful. I have the CD for it, and every time i run it, it takes forever, and doesnt seem to do anything. After a while, at the bottom, a few numbers and file names appear. it counts up from 1, and just keeps going up every second. It reached 8500 until i turned it off. Why will 11.04 get installed?

I used to have the same problem with updating, it was my hardware I think , I used different method of installation (used all the different options) but nothing worked.
Have you taken different options to see if it works? Do you have enough Hard Drive space left for an update?
Anyway now I do a partition-less install using Wubi but that is an exe file and only works in Windows. If they have something like Wubi for Linux, it would be excellent cuz it works great. (May be you can use Wine to run Wubi inside Ubuntu)? it is a 1.4 meg file but it picks up the latest version of Ubuntu for you and installs it.
good luck.

I did a mistake when I was running some programs. By mistake I pressed the update button on the software update page. Immediately I pressed the cancel button to cancel the update installation. But I didn’t able to cancel it. Then I pressed the shut down button immediately. After that when I started the computer, I didn’t able to open the computer anymore. it shows some spectral line on the screne.

Please give me some suggestion. Thank you.

It’s writing command not found on my machine.
