Claude Code on Ubuntu Linux, The Curated Walkthrough
An exclusive resource for students of Arun's Claude Code Course.
This course is recorded on a Mac. Rather than a generic Linux walkthrough that may not match your screen, here is a tutorial that installs Claude Code end to end on real hardware.

It uses the same curl installer as the macOS lecture, walks through a first session, and shows the Visual Studio Code extension at the end if you want it.
The instructions work for Ubuntu and Debian directly, and the same install command works on Fedora, Arch and most other distributions, because the installer is universal across the family.
Three things to watch for while it plays
These are the moments where Linux installs most often go sideways, and where the video saves you the most time.
One, Node.js. Confirm the walkthrough checks your Node version before running the installer. If your distribution ships with an older Node, it should show you either upgrading through your package manager or using a version manager to pull a current release.
Two, PATH configuration. The installer drops the program into ~/.local/bin. On most distributions that folder is already on your PATH and everything just works. On some minimal setups it is not, and that is when you need the one-line fix from the command sheet.
Three, authentication. Identical to macOS. The first time you run claude, your browser opens, you sign in once, and your credentials are cached locally.
After the walkthrough
Run the same two checks, and if both come back clean you are ready for the rest of the section.
claude --version claude doctor
One advantage Linux users have
If you run Claude Code inside a Docker container, a cloud VM, or a remote server, the install process is identical to the local-machine walkthrough. Same curl command, same verification flow. Once you have installed once, you have effectively learned how to install on every Linux environment you will meet.
