Setup covers choosing a tenant name, configuring your identity provider, verifying your domain over DNS, and optionally enforcing SSO for the whole organization. SSO is $250/month. Learn more.

Bugfix: Fixed FUSE mounts failing on Ubuntu runners with fusermount3: mount failed: Operation not permitted. A non-setuid fusermount3 at /usr/local/bin was shadowing the setuid system binary on PATH, so unprivileged mounts were denied (actions/runner-images#14516). Tools that resolve fusermount3 via PATH were affected; those calling it by absolute path were not. Ubuntu 22.04 and 24.04 were affected on both x64 and Arm64; Ubuntu 26.04 was not.
