Visual Studio Code on Linux

Installation

See the Download Visual Studio Code page for a complete list of available installation options.

By downloading and using Visual Studio Code, you agree to the license terms and privacy statement.

Debian and Ubuntu based distributions

The easiest way to install Visual Studio Code for Debian/Ubuntu based distributions is to download and install the .deb package (64-bit), either through the graphical software center if it’s available, or through the command line with:

Note that other binaries are also available on the VS Code download page.

Installing the .deb package will automatically install the apt repository and signing key to enable auto-updating using the system’s package manager. Alternatively, the repository and key can also be installed manually with the following script:

Then update the package cache and install the package using:

RHEL, Fedora, and CentOS based distributions

We currently ship the stable 64-bit VS Code in a yum repository, the following script will install the key and repository:

Then update the package cache and install the package using dnf (Fedora 22 and above):

Or on older versions using yum :

Due to the manual signing process and the system we use to publish, the yum repo may lag behind and not get the latest version of VS Code immediately.

Visual Studio Code is officially distributed as a Snap package in the Snap Store:

You can install it by running:

Once installed, the Snap daemon will take care of automatically updating VS Code in the background. You will get an in-product update notification whenever a new update is available.

Note: If snap isn’t available in your Linux distribution, please check the following Installing snapd guide, which can help you get that set up.

Learn more about snaps from the official Snap Documentation.

openSUSE and SLE-based distributions

The yum repository above also works for openSUSE and SLE-based systems, the following script will install the key and repository:

Then update the package cache and install the package using:

AUR package for Arch Linux

To get more information about the installation from the AUR, please consult the following wiki entry: Install AUR Packages.

Nix package for NixOS (or any Linux distribution using Nix package manager)

There is a community maintained VS Code Nix package in the nixpkgs repository. In order to install it using Nix, set allowUnfree option to true in your config.nix and execute:

Installing .rpm package manually

The VS Code .rpm package (64-bit) can also be manually downloaded and installed, however, auto-updating won’t work unless the repository above is installed. Once downloaded it can be installed using your package manager, for example with dnf :

Note that other binaries are also available on the VS Code download page.

Updates

VS Code ships monthly and you can see when a new release is available by checking the release notes. If the VS Code repository was installed correctly, then your system package manager should handle auto-updating in the same way as other packages on the system.

Note: Updates are automatic and run in the background for the Snap package.

Node.js

Node.js is a popular platform and runtime for easily building and running JavaScript applications. It also includes npm, a Package Manager for Node.js modules. You’ll see Node.js and npm mentioned frequently in our documentation and some optional VS Code tooling requires Node.js (for example, the VS Code extension generator).

If you’d like to install Node.js on Linux, see Installing Node.js via package manager to find the Node.js package and installation instructions tailored to your Linux distribution. You can also install and support multiple versions of Node.js by using the Node Version Manager.

To learn more about JavaScript and Node.js, see our Node.js tutorial, where you’ll learn about running and debugging Node.js applications with VS Code.

Setting VS Code as the default text editor

xdg-open

You can set the default text editor for text files ( text/plain ) that is used by xdg-open with the following command:

Debian alternatives system

Debian-based distributions allow setting a default editor using the Debian alternatives system, without concern for the MIME type. You can set this by running the following and selecting code:

If Visual Studio Code doesn’t show up as an alternative to editor , you need to register it:

Windows as a Linux developer machine

Another option for Linux development with VS Code is to use a Windows machine with the Windows Subsystem for Linux (WSL).

Windows Subsystem for Linux

With WSL, you can install and run Linux distributions on Windows. This enables you to develop and test your source code on Linux while still working locally on a Windows machine. WSL supports Linux distributions such as Ubuntu, Debian, SUSE, and Alpine available from the Microsoft Store.

When coupled with the Remote — WSL extension, you get full VS Code editing and debugging support while running in the context of a Linux distro on WSL.

See the Developing in WSL documentation to learn more or try the Working in WSL introductory tutorial.

Common questions

Azure VM Issues

I’m getting a «Running without the SUID sandbox» error?

You can safely ignore this error.

Debian and moving files to trash

If you see an error when deleting files from the VS Code Explorer on the Debian operating system, it might be because the trash implementation that VS Code is using is not there.

Run these commands to solve this issue:

Conflicts with VS Code packages from other repositories

Some distributions, for example Pop!_OS provide their own code package. To ensure the official VS Code repository is used, create a file named /etc/apt/preferences.d/code with the following content:

«Visual Studio Code is unable to watch for file changes in this large workspace» (error ENOSPC)

When you see this notification, it indicates that the VS Code file watcher is running out of handles because the workspace is large and contains many files. Before adjusting platform limits, make sure that potentially large folders, such as Python .venv , are added to the files.watcherExclude setting (more details below). The current limit can be viewed by running:

The limit can be increased to its maximum by editing /etc/sysctl.conf (except on Arch Linux, read below) and adding this line to the end of the file:

The new value can then be loaded in by running sudo sysctl -p .

While 524,288 is the maximum number of files that can be watched, if you’re in an environment that is particularly memory constrained, you may want to lower the number. Each file watch takes up 1080 bytes, so assuming that all 524,288 watches are consumed, that results in an upper bound of around 540 MiB.

Arch-based distros (including Manjaro) require you to change a different file; follow these steps instead.

Another option is to exclude specific workspace directories from the VS Code file watcher with the files.watcherExclude setting. The default for files.watcherExclude excludes node_modules and some folders under .git , but you can add other directories that you don’t want VS Code to track.

I can’t see Chinese characters in Ubuntu

We’re working on a fix. In the meantime, open the application menu, then choose File > Preferences > Settings. In the Text Editor > Font section, set «Font Family» to Droid Sans Mono, Droid Sans Fallback . If you’d rather edit the settings.json file directly, set editor.fontFamily as shown:

Package git is not installed

This error can appear during installation and is typically caused by the package manager’s lists being out of date. Try updating them and installing again:

The code bin command does not bring the window to the foreground on Ubuntu

Running code . on Ubuntu when VS Code is already open in the current directory will not bring VS Code into the foreground. This is a feature of the OS which can be disabled using ccsm .

Under General > General Options > Focus & Raise Behaviour, set «Focus Prevention Level» to «Off». Remember this is an OS-level setting that will apply to all applications, not just VS Code.

Cannot install .deb package due to «/etc/apt/sources.list.d/vscode.list: No such file or directory»

This can happen when sources.list.d doesn’t exist or you don’t have access to create the file. To fix this, try manually creating the folder and an empty vscode.list file:

Cannot move or resize the window while X forwarding a remote window

If you are using X forwarding to use VS Code remotely, you will need to use the native title bar to ensure you can properly manipulate the window. You can switch to using it by setting window.titleBarStyle to native .

Using the custom title bar

The custom title bar and menus were enabled by default on Linux for several months. The custom title bar has been a success on Windows, but the customer response on Linux suggests otherwise. Based on feedback, we have decided to make this setting opt-in on Linux and leave the native title bar as the default.

The custom title bar provides many benefits including great theming support and better accessibility through keyboard navigation and screen readers. Unfortunately, these benefits do not translate as well to the Linux platform. Linux has a variety of desktop environments and window managers that can make the VS Code theming look foreign to users. For users needing the accessibility improvements, we recommend enabling the custom title bar when running in accessibility mode using a screen reader. You can still manually set the title bar with the Window: Title Bar Style ( window.titleBarStyle ) setting.

Broken cursor in editor with display scaling enabled

Due to an upstream issue #14787 with Electron, the mouse cursor may render incorrectly with scaling enabled. If you notice that the usual text cursor is not being rendered inside the editor as you would expect, try falling back to the native menu bar by configuring the setting window.titleBarStyle to native .

Repository changed its origin value

If you receive an error similar to the following:

Use apt instead of apt-get and you will be prompted to accept the origin change:

How to get source code of package using the apt-get/apt command

The procedure to download source code is as follows for Ubuntu Linux.

Please note that apt-get does support third-party closed-source applications. You can only download the source code of open-source software.

Step 1 – Enable source code repo

Sources are normally not installed. Hence, you can only install them if you know the package name and when you enable them. Therefore, edit the /etc/apt/sources.list file, run:
$ sudo vi /etc/apt/sources.list
Make sure the deb-src type references an Ubuntu distribution’s source code as follows:
# Sources specification for the Ubuntu 20.04 LTS distro #
deb-src http://archive.ubuntu.com/ubuntu focal main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu focal-updates main restricted universe multiverse
deb-src http://security.ubuntu.com/ubuntu focal-security main restricted universe multiverse
Where,

1. deb-src : Indicate that you need source code for .DEB files.
2. http://archive.ubuntu.com/ubuntu : URL to fetch index and .deb files source code.
3. focal : Ubuntu Linux 20.04 LTS code name
4. main restricted universe multiverse : State component name for repo such as main, restricted, universe, and multiverse

Step 2 – Update index

Run the following command to resynchronize the package index files from their sources as defined by the deb-src keyword in /etc/apt/sources.list for Ubuntu Linux
$ sudo apt-get update
# OR #
$ sudo apt update

Step 3 – Download Ubuntu package’s source code

Let us download source code for bash shell, run:
$ sudo apt-get source $ sudo apt-get source bash

You may see the following error if you forgot to set up deb-src as explained in step # 1:

E: You must put some ‘source’ URIs in your sources.list

Step 4 – Understanding downloaded source code files

Let us run the ls command to see source code:
$ ls -l

By default, the source code is extracted into bash-5.0 directory:
$ cd bash-5.0
$ ls
The upstream bash source tarball with .tar.xz ending is stored in bash_5.0.orig.tar.xz file. A description file with .dsc ending contains the name of the package, both, in its filename as well as content (after the Source: keyword). A tarball, with any changes made to upstream source, plus all the files created for the Debian package stored in bash_5.0-6ubuntu1.1.debian.tar.xz file. If the —download-only option passed to the apt-get command, then the source package will not be unpacked:
$ sudo apt-get —download-only source source bash
When downloaded, we can extract the source files for bash as follows:
$ dpkg-source -x /path/to/pkg.dsc
$ dpkg-source -x bash_5.0-6ubuntu1.1.dsc
It is also possible to build packages:
$ sudo apt-get —build source $ sudo apt-get —build source bash
Another option is to make changes in debian/rules files
$ vi bash-5.0/debian/rules
Next we can build out custom bash package as follows:
$ export EDITOR=vim
$ dch -n
Make sure we satisfy the build dependencies for a source package and to avoid errors install those libs and tools:
$ sudo apt-get -y build-dep bash
Finally, build a Debian package:
$ debuild
Verify new packages:
$ cd ..
$ ls *.deb
Install them:
$ sudo dpkg -i bash_*.deb

How to download Debian package’s source code

The procedure is the same as Ubuntu distro but URL syntax changes as follows:
$ sudo vi /etc/apt/sources.list
Edit/update as follows:
# source repo for Debian 10 buster #
deb-src deb http://deb.debian.org/debian buster main
Save and close the file in vim, and then run the following command:
$ sudo apt-get update
Let us download source code for the Apache web server:
$ apt-get source apache2

Conclusion

We explained how to enable Ubuntu/Debian source repo and download source code for the package by name. The apt-get source command is useful when you want to study packaging or a specific Debian package. Also useful to know which compile-time options enabled for a particular package. And finally, we can rebuild packages to add or remove components. See Debian guide wiki page for more information and read the following man pages by typing the man command:
$ man apt
$ man apt-get
$ man 5 sources.list
$ man debuild
$ man dch
