CI failures are due to old versions of ament_lint packages being used (ament/ament_lint#428). I'll bump the version in a separate PR.

[emersonknapp]

LGTM. Users continue to build EOL Galactic apps, as long as they keep pinned to an older version of action-ros-ci, correct?

[christophebedard]

Yes and no. I haven't removed "galactic" from the list of accepted distros (because I/we didn't remove the other EOL distros from that list), so it might work fine for a little while more. No real need to pin an older version.

We don't explicitly forbid users from selecting Galactic, but we just don't support it officially going forward.
