Linux support for the Claude desktop app is in beta.
The desktop app on Linux gives you the same Chat, Cowork, and Claude Code experience as on macOS and Windows: parallel sessions, visual diff review, an integrated terminal and editor, and live app preview. See Use Claude Code Desktop for the feature reference.

​
Requirements

  • Ubuntu 22.04 or later, or Debian 12 or later
  • x86_64 or arm64
Other Debian-based distributions that meet these requirements may work but aren’t officially tested. On distributions that aren’t Debian-based, such as Fedora or Arch, run the CLI instead. If you work on Windows with WSL 2, install the Windows desktop app and run sessions inside your distribution; see Claude Code Desktop in WSL.

​
Cowork requirements

Cowork is the desktop tab for Dispatch and longer agentic work. On Linux, Cowork runs those tasks in a virtual machine that the desktop app hosts with QEMU and KVM. To use Cowork, your machine needs:
  • Hardware virtualization: turned on in your firmware settings. Without it, the Cowork tab reports “Cowork requires hardware virtualization (KVM)”.
  • QEMU and UEFI firmware: qemu-system-x86, ovmf, and virtiofsd on x86_64, or qemu-system-arm, qemu-efi-aarch64, and virtiofsd on arm64. apt install claude-desktop installs them by default as recommended packages. If you installed with --no-install-recommends, or your system is a minimal image that skips recommended packages, the Cowork tab reports “Cowork requires QEMU” and shows the apt install command to run. Ubuntu 22.04 has no virtiofsd package; the app uses a bundled copy there.
  • Access to /dev/kvm: add your user to the kvm group with sudo usermod -aG kvm $USER, then log out and back in. Some desktop environments grant the logged-in user access to /dev/kvm without the group, but Cowork also needs /dev/vhost-vsock, which only kvm group members can open. Join the group even if /dev/kvm already works for you.
The app checks these requirements once at launch: restart it after installing packages, and log out and back in after joining the group. If /dev/vhost-vsock is missing and your running kernel has no module directory under /lib/modules, the Cowork tab reports that the kernel doesn’t include the virtualization support Cowork needs and that it can’t be added manually. This combination is common on ChromeOS and in container-based Linux environments.

​
Install

Install from Anthropic’s apt repository so that updates arrive through your system’s regular package updates. Open a terminal and run the commands in each step.
1

Add Anthropic's apt repository

This step downloads the signing key with curl and verifies it with gpg, which fresh Debian and Ubuntu installations may not include. If either command reports command not found, install both first:
Download Anthropic’s signing key:
The command prints nothing when it succeeds and a curl: error when it doesn’t. A missing or wrong key makes apt update fail later with NO_PUBKEY BAA929FF1A7ECACE, so confirm the key downloaded and belongs to Anthropic before continuing:
The fingerprint gpg prints should be 31DDDE24DDFAB679F42D7BD2BAA929FF1A7ECACE. If gpg reports that the file can’t be opened or contains no valid OpenPGP data, the download failed or returned the wrong content: confirm your network can reach downloads.claude.ai, then rerun the download command.Register the repository:

Install the package

Launch and sign in

Launch Claude from your application launcher, or run claude-desktop from a terminal, and sign in with your Anthropic account.The Linux app signs in the same way as on macOS and Windows: with a claude.ai subscription, or through your organization’s SSO. Desktop doesn’t accept a Claude Console API key directly; use the CLI for API-key authentication. For enterprise deployments that route Desktop to Google Cloud’s Agent Platform or an LLM gateway, see Claude Desktop on 3P and network configuration.

​
Install from a downloaded file

If you can’t install through the apt repository, download the .deb package directly from the repository’s package pool. This command looks up the newest package for your architecture in the repository index, then downloads it to the current directory:
If the command fails with Remote file name has no length, the lookup returned no package path. This can mean the repository index couldn’t be fetched, for example when your network blocks downloads.claude.ai, or that no package exists for your architecture. Confirm that your network can reach downloads.claude.ai and that dpkg --print-architecture prints amd64 or arm64; the repository doesn’t publish packages for other architectures. To install without registering Anthropic’s apt repository, first create /etc/default/claude-desktop with the line CLAUDE_DESKTOP_ADD_REPO="false". Without the repository, apt doesn’t deliver new versions; to update, re-run the download command and reinstall, or register the repository later. Then open the downloaded file with your software installer, such as GNOME Software, or install it with apt from the directory that contains the downloaded file:
If apt reports E: Unsupported file ./claude-desktop_*.deb given on commandline, the pattern didn’t match a .deb file in the current directory. Confirm the download completed, then run the command again from the directory that contains the file. Installing the .deb also registers Anthropic’s apt repository at /etc/apt/sources.list.d/claude-desktop.list, so future updates arrive with your system’s regular package updates.

​
Update

The desktop app doesn’t update itself on Linux. Updates arrive with your system’s regular package updates:
Your distribution’s graphical software updater will also pick up new versions.

​
Uninstall

Uninstalling the package also removes the repository entry and signing key it registered. If you added the repository entry yourself with the Add Anthropic’s apt repository step, remove it too:

​
Troubleshoot

​
Unable to locate package claude-desktop

If sudo apt install claude-desktop fails with E: Unable to locate package claude-desktop, apt didn’t find the repository you added. Check the following:
  • Run sudo apt update after adding the repository. apt install on its own doesn’t see a repository you added after the last time you ran apt update.
  • Confirm the repository entry was written. cat /etc/apt/sources.list.d/claude-desktop.list should show the deb line from the Add Anthropic’s apt repository step. If the file is empty or missing, run that step again.
  • Confirm your architecture is supported. dpkg --print-architecture should print amd64 or arm64. The repository doesn’t publish packages for other architectures.
  • Run sudo apt update again and check its output for errors related to downloads.claude.ai. A network or key error there means the repository was added but couldn’t be reached or verified.
If the repository is in place and reachable and the package is still not found, install from a downloaded file instead.

​
Unmet dependencies

If apt stops with The following packages have unmet dependencies or Unsatisfied dependencies, read which dependency it names:
  • libc6 (>= 2.34): your distribution is older than the package supports. Ubuntu 20.04 ships libc6 2.31. Upgrade to Ubuntu 22.04 or later, or Debian 12 or later.
  • All missing dependencies show not installable with an :amd64 or :arm64 suffix: you downloaded the .deb for a different architecture than your machine’s. Run dpkg --print-architecture and download the matching .deb, or install from the apt repository, which selects the package for your architecture.

​
Running as root without —no-sandbox is not supported

If claude-desktop exits with this message, you launched it as root. Log in as a regular user and launch it from there.

​
Cowork isn’t available

If the Cowork tab shows one of these messages, fix the requirement it names, then restart the app:
  • Cowork requires QEMU: install the QEMU and UEFI firmware packages the message lists.
  • Cowork requires hardware virtualization (KVM): turn on hardware virtualization in your firmware settings.
  • Claude doesn’t have permission to use virtualization (/dev/kvm): add your user to the kvm group, then log out and back in.
  • Cowork requires the vhost_vsock kernel module: run sudo modprobe vhost_vsock, then restart the app. That loads the module for the current boot only. To load it on every boot, run echo vhost_vsock | sudo tee /etc/modules-load.d/vhost_vsock.conf.

​
What’s not in the Linux beta yet

  • Computer Use: app and screen control isn’t available on Linux.
  • Dictation: voice input isn’t available in the Linux desktop app. Use voice dictation in the CLI instead.
  • Quick Entry global hotkey: works on X11. On native Wayland it requires your desktop environment’s GlobalShortcuts portal.
  • Fedora and RHEL: only Debian-based distributions are supported today. Support for additional distributions is coming in the future.
For anything not yet available in the desktop app, the CLI runs the same Claude Code engine and supports a wider range of Linux distributions; see the system requirements.
