An independent guide to Claude Desktop on Linux: the apt install on Ubuntu and Debian, the Cowork KVM requirement, and the open-source route that runs the agent on a cloud computer. https://claudedesktoplinux.com/ 2026-10-27T00:00:00Z Claude Desktop Linux https://claudedesktoplinux.com/ 2026-10-27T00:00:00Z

Claude Desktop for Linux installs with apt on Ubuntu and Debian. Cowork needs KVM and /dev/vhost-vsock; the open source route runs the agent in the cloud.

Anthropic's Linux beta of the Claude desktop app installs with apt on Ubuntu and Debian. Cowork then needs /dev/kvm and /dev/vhost-vsock, devices only the kernel can expose. The open source route runs the agent on a cloud computer instead, so the virtual machine stays off your machine. https://claudedesktoplinux.com/ubuntu-debian 2026-10-27T00:00:00Z

Claude Desktop installs on Ubuntu 22.04 and Debian 12 from Anthropic's apt repo. Cowork then needs /dev/vhost-vsock; open source runs the agent elsewhere.

Claude Desktop installs on Ubuntu 22.04 and later and on Debian 12 and later, from Anthropic's own apt repository, in three documented steps. The virtual machine Cowork runs is the part your kernel has to allow. Kortix, the open-source AI Operating System, runs the agent work when the machine in front of you cannot. https://claudedesktoplinux.com/arch-fedora-nixos 2026-10-27T00:00:00Z

Outside Debian, Claude Desktop comes from a repackaging: AUR, an MIT Fedora script, an AppImage or a Nix flake. Open source Kortix runs the agent instead.

Outside Debian, the Claude desktop app arrives as somebody's repackaging of Anthropic's .deb, so the choice is a maintainer and an update path. Kortix is the open-source AI Operating System, with each session on its own isolated machine and reached from a browser tab on whatever distribution your laptop boots. https://claudedesktoplinux.com/cowork-linux-kvm 2026-10-27T00:00:00Z

Cowork on Linux needs KVM, /dev/vhost-vsock and QEMU. What each error checks, the fix where one exists, and the open source route off the host.

Claude Cowork boots a virtual machine on your own computer, so the errors it reports on Linux describe the host. Each message belongs to one check, and some hosts have no local fix at all. Kortix, the open-source AI Operating System, gives every agent session its own cloud computer, so the machine is not yours to configure. https://claudedesktoplinux.com/containers-chromeos-servers 2026-10-27T00:00:00Z

ChromeOS, containers, headless servers and WSL 2 stop Cowork on the same missing /dev/vhost-vsock. What still runs locally, and the open source host.

Claude Desktop installs on a Chromebook or in a container image, a headless server has no desktop to launch it from, and WSL 2 has its own route through Windows. Cowork starts on none of them, for one shared reason. Kortix, the open-source AI Operating System, runs the session on a cloud computer instead. https://claudedesktoplinux.com/agent-on-linux 2026-10-27T00:00:00Z

Claude Desktop and the CLI split the work by job on Linux. What a question, a repo change, and an hour-long run each need, plus the open source route.

Claude Desktop and the Claude Code CLI sit on one account and divide the work by job. On Linux the split turns on what each job needs from the machine. Kortix, the open-source AI Operating System, covers the job that has to outlive the laptop.
