Linux live user password

What is the default password for a Linux Mint live usb

Im sure some else has had this problem before, but I can’t seem to find a proper answer. What is the default password for a linux mint live usb?

Most of the other answers say that my install would be corrupt if it is asking me; however, I need to know because I am trying to ssh into it.

The username for the live session is mint . If asked for a password press Enter .

No (publicly known) password for the default user

There is no (publicly known) password for the default user in Ubuntu based flavours and distros. When asked for a password, for example to run sudo, you simply press the Enter key. But ssh wants a password, so it does not work to log in remotely via ssh into a persistent live drive.

Create a second user with a password

I found a way to connect to a persistent live Ubuntu based distro via ssh. I tested with a recent iso file of Lubuntu Eoan (to be released as 19.10), but I think the method is general and should work for many versions, flavours and re-spins based on Ubuntu including Linux Mint.

• Create a persistent live drive with mkusb from your iso file.
• Boot into your persistent live system

Get packages (unless you have them already)

in order to get users-admin and of course

The default live user needs no password to run sudo, just press the Enter key, when it asks for password.

Create a second user

and follow the instructions in the graphical user interface. Select a good password with at least 8 characters.

Now you have an ssh server and a user with a password, and you can log in remotely to your persistent live system 🙂

Connect to your network and identify your IP address

I found the following address: 192.168.1.10

Demo input and output

You can see that the root file system / has the same properties as the casper-rw partition. It indicates that it is a persistent live system. You can also see that it is possible to switch user to the default user (here ‘lubuntu’).

Live session user password?

Live session user password?

Post by ZarK-eh » Wed Jun 07, 2017 7:01 pm

I downloaded 18.1 cinnamon 32bit to try out some retro gaming. verified sha256’d okay. booted. went to sleep and now at a login prompt.

I searched for a password, but only found ‘invalid; bug or that the password is blank (with user mint). If I install this I won’t have issues of the screensaver ‘forgetting’ my password? can I configure the resume to not ask for a password? . what about cpu power levels like win. nevermind that’s off topic lol.

I’m stuck at this livedvd session user password prompt! alls I wanted to do was install.

I replicated the problem by using suspend and resume. That login screen has no user box, only a place to enter a password and a couple icon/buttons which don’t seem to do anything.

And, now installing and wiggling the mouse to prevent sleeping. So this problem will only crop up if a livecd is left running.

Thank you Mute Ant, I’ll have to remember those again. I did see the alternate consoles, but was trying to rescue the live session.

«no user box, only a place to enter a password» which is an empty string, just press . It has been known that the GUI simply refuses to accept an empty string as a password. hopefully this will be cured by Mint Sonya moving to LightDM as the display manager.

«So this problem will only crop up if a livecd is left running.» No promises. Obviously it’s a bug, but no-one seems to know how to reliably provoke the problem, so it’s a pig to fix it. The work-around is to log in and disable the Lock Screen feature, possibly to switch on Timed Auto-Login as well.

«Wiggling the mouse to prevent sleeping.» Beastliness! Should I report this to Miss Rosemary Palm or the RSPCA?

Was able to replicate this by using suspend (with a LiveCD instance).

Not sure if this is reproducable on all mainboards, but FWIW I am using an old Amd Duron AGP board to get my retro gaming fix on and wondered if I could use an updated OS instead of some windows.

Also, I found Ctrl-Alt-F7 to return to the GUI I started from. one of the first things I did was panic and try ctrl-alt-effitkeys

So, apparently the gui login screen of the live cd is configured to not allow logins with a blank password. That’s an easy fix for the devs, you know. Or if you want to prevent the inevitable clueless user from being able to use blank passwd themselves, they could bake in a really friggin obvious password (password same as user name, aka mint). Why did I need it? Not because I’m clueless, I can tell you that. Don’t @ me.

Because I was running a machine with an unreliable hard drive off of the livecd as a means to recover files from it! And got distracted long enough for the screen saver to kick in and lock the screen on me! Why IS the screensaver even configured to lock?!

Going to an alternate terminal, assigning a quick & easy non-blank password like «uhuhuhuh» lets you get back into a current live session, no reset, when you get back to the gui (ctrl-alt-7 or -8, depending). If you do a permanent install please use something better

Live Session User — su password?

Live Session User — su password?

Post by Topher_Linux » Fri May 16, 2014 1:51 pm

I’m running Linux Mint 16 Mate on a flashdrive. Because of this it was not installed like normal, but instead boots up to the Live user account. It was created with the Universal USB installer. (http://www.pendrivelinux.com/universal- . -as-1-2-3/)

When playing around with terminal I’ve run into a hitch with the password. I’ve never set one, and everything I’ve tried doesn’t work. (I’ve tried «password», «root», just pressing Enter, ect. )

Does anyone know what the default password is for a Live session user in Linux Mint 16?

Hmm. so far no luck with any of those answers. Maybe I should explain what I am trying to do.

So I’m booted to the Live user account off a flashdrive like I wrote earlier. Now I am trying to install Pale Moon for Linux. I’ve download the file ‘pminstaller-0.1.3.tar.bz2’, extracted it, and then read the README. The readme tells me to install the program by typing «su -c ./pminstaller.sh» from the terminal.

But when I do this is asks for a password. None of the passwords I’ve tried have worked. I tried entering no password and just pressing enter. I’ve already tried «password» and «passwd». Every time it gives me the error «su: Authentication failure»

Other commands I’ve tried.
sudo -c ./pminstaller.sh
sudo -i -c ./pminstaller.sh
sudo -i ./pminstaller.sh
su -i -c ./pminstaller.sh
su -i ./pminstaller.sh

So far, none of those have worked. Unless I am doing something wrong here. Does anyone know what I might be overlooking?

If that doesn’t work, try > logout and then log in as user mint. pw should be blank but if that doesnt work, try «mint» as the pw.

«mint», «Mint», and «MINT» don’t work.

If I try to Logout and then Switch User it places me on a screen where I can’t do anything except to Shutdown, Suspend, or Restart.

What is the password of a live user?

I installed Xubuntu on a pen drive to use as live (with persistence) and I cannot put a password.

It asks to enter the «current password», but I never changed any kind of password.

I’ve tried to leave it blank, but it will not accept that. I also tried to create another user with password, and it worked, but the system does not connect directly to it on boot. And I already tried to delete the user with no password there.

(Sorry if there are any spelling mistakes. I used Google Translate.)

There is no default password for the live user. It is blank. It seems though, that the GUI app you’re using doesn’t let you leave the password blank.

You can change it by opening a terminal and typing

It’ll also ask you for the current password. Just press enter.

Introduction

A live drive (and also a persistent live drive) is easy to read for everybody. So you do not really protect your data with a login password. Your data need encryption.

The following descriptions were made after I tested with Lubuntu 16.04.x ‘Xenial’ systems

• persistent live, created with mkusb from a Lubuntu desktop iso file,
• installed with encrypted disk, created according to the testcase described in this link.

See the following link and links from it for more details about live systems, persistent live systems and installed systems in external drives: Try Ubuntu (Kubuntu, Lubuntu, Xubuntu, . ) before installing it

I think that the following descriptions can be used with Xubuntu systems too (but the link to the testcase is made for a Lubuntu alternate iso file).

Another user with encrypted home

The quick fix is to create another user in your persistent live system. In Lubuntu (and I think also in Xubuntu) there is ‘Users and Groups’ in the System sub-menu. This menu entry runs the program users-admin , which can be installed with the following command, if it is not already there in Xubuntu,

Start ‘Users and Groups’, select +ADD to add a new user, tick the box to ‘Encrypt home folder to protect sensitive data’ and fill in ‘Name’ and ‘Username’.

In the next window you should select a good password.

Let the system boot into the standard user (after cold boot or reboot), logout, select the new user and its password and login. Edit: This was fixed by the original poster as described in a comment by removing the live user ‘xubuntu’ (user #999).

After login you should save the passphrase for the encrypted home, when prompted. And take regular backups because [even with the passphrase] it is difficult to recover the data, if the system is damaged.

You may want ‘full access’ including running sudo from this new user. You can give such permissions by adding the username to lines in the file /etc/group , with the username ‘xubuntu’ at the end of the line.

Example: assuming the new username is crypt

Warning: Reboot or shutdown to protect your data

If you logout from the new user with encrypted home, and login to the standard user xubuntu, you will still be able to read the files, that have been opened by the new user with encrypted home. So don’t leave the computer at the login screen. Instead you should reboot or shutdown in order to protect your data.

Installed system with encrypted disk

The most reliable system is an installed system with encrypted disk, select ‘Guided — use entire disk and set up encrypted LVM’ in the partitioning window of the installer.

I mean installed like into an internal drive, but to an external drive, for example a fast USB 3 pendrive. An installed Ubuntu system is portable between computers, if you avoid (and need no) proprietary drivers (typically for the graphics chip or wifi chip).

It is easiest to install this system, if you remove the internal drive before doing it. This is particularly important, if your computer is running in UEFI mode.

Passphrase, password

It is important to select a good and long passphrase (to unlock the encrypted disk). This passphrase must be difficult to guess, but you must always remember it or write it on a paper and store it in a safe place, not near the drive. (Mix upper case and lower case letters and use at least one digit or other non-alphabetic character.)

Think in the same way to get a good login password for the new user in the persistent live system with encrypted home.

Live CD asks for a username and password

When I boot Ubuntu 10.04.3 from a live CD, it asks me to enter a username and password. I have not booted before, and I haven’t created an account.

8 Answers 8

The default username is ubuntu, and the password is blank on an Ubuntu LiveCD.

If the username «ubuntu» with an empty password doesn’t work, you may be able to add a new user to the system as follows.

Press Ctrl + Alt + F1 and run this command:

Meanwhile in some other Ubuntu-Based Distros (especially official ones), the username goes by their distro name (e.g: Xubuntu=’xubuntu’, Lubuntu=’lubuntu’ etc) though you can also find the username of it on some distros by looking at the upper-left hand corner.

While it’s ubuntu for Ubuntu live images it also depends on the flavor. For Edubuntu it’s edubuntu .

Known users and passwords so far (nothing after a colon means a blank password):

• Ubuntu: ubuntu:
• Kubuntu: kubuntu:
• Lubuntu: lubuntu:
• LXLE: qwerty:
• Ubuntu-studio: ubuntu-studio:
• Edubuntu: edubuntu:
• ChaletOS: chaletos-user:
• Xubuntu: xubuntu:
• Ubuntu Mate: ubuntu-mate:
• Ubuntu Budgie: ubuntu-budgie:

This is an answer to a very old question. None of the above have ever worked for me.

The last time I had this problem was after trying to move «home» from / to /home using cut and paste, (I was in a rush).

After using rsync to move home, the problem went away.

I have previously seen this problem caused mostly by bad persistence files.

Check if the problem persists with a live boot (non-persistent).

Confirm there is space in the casper-rw file or partition.

Try a different boot disk creator program.

Try the USB stick on a different computer.

Exceptions:

Syslinux type installers including Rufus, Startup Disk Creator, UNetbootin, Universal and YUMI do not use ubuntu as the default user, they use Live session user instead.

For these installers after logging out you can hit enter to log back in. After a suspend simply pressing the power button brings you back to desktop.

Grub type installers, ie mkusb also use Live session user as user and a blank password when logging back in. After a suspend simply pressing the power button brings you back to desktop.

Live CD/DVD also uses Live session user for user name, it is supplied automatically. After logging out, a password is not asked for when logging back in. After suspend, pressing the power button will bring you back to desktop.

In summary, under normal circumstances, no user name or password should need to be entered when logging into 18.04 CD/DVD and Live or Persistent USB’s

I have encountered this issue and here is how I worked around this issue:

If the username is «ubuntu» as it should be and if no password is needed to execute a sudo command, you will still be asked for a password after logging out when logging back in and a blank password usually won’t work here.

To get around this, just open a terminal and execute the following command:

follow the prompts and set a password; the current password is blank so if it asks for a password here or for sudo , just press enter .

Now, when the system asks for a password, you will have one and this should work around your problem.

You may need to execute this command from a TTY.

Rewriting the same image to USB a second time prevented the login screen from appearing.

I had the same issue on an HP Elitebook Folio 1040 with the standard 16.04.1 image, downloaded and copied to USB with usb-creator-gtk 0.2.23. None of the above mentioned username/password combinations worked for me.

Not blank. example in 14.10 live I installed xfce4 then logged out. Had to add a user. To do so press Ctrl + Alt + F2 . You should now see a console. Type sudo adduser anyname and follow the instructions. Afterwards press Ctrl + Alt + F7 . You should be at the graphic login able to use the info you created.

It seems that for some reason in Ubuntu 18.04 Desktop the install media which I just downloaded and verified via md5, and sha256 hashes along with using the gpg signatures to validate the md5, and sha256 hashes from http://mirror.math.princeton.edu/pub/ubuntu-iso/18.04/ubuntu-18.04-desktop-amd64.iso that you can not utilize the tty2 as in past installer executions. The tty2 screen is now asking for a username/password pair to access tty2 which is NOT ubuntu:. Please not that in the past that tty1 were non GUI (tty1 was for dmesg logging for errors thrown while installing, however tty2 were usually available to the user to access the command line, tty7 was generally set aside as the graphical interface for the installer up through 16.x while 17.x and newer moved the graphical installer screen to tty1) and defaulted to a sh/bash or similar command shell without any username/password login. As there is a definite use for having access to the command line while installing I would recommend a check that this is indeed the desired action to have while the installer is running.

Further testing of usernames failed to allow me into the terminal. Usernames I tried were and yet all listed below failed the username/password check. root:root root: ubuntu: ubuntu:ubuntu Ubuntu: Ubuntu:Ubuntu

I got around this issue by moving the mouse around until it completed its boot cycle. It looks like the screen is locking, that is why it wants the password. By continuously moving the mouse, the screen never locked.

Perhaps the Ubuntu devs should consider changing the setting so that the screen does not lock or it does not require a password when it is locked.
