ruby:latest is incompatible with listen-3.2.1

I tried to copy-paste deploy this repo with Gitlab pages. On the first try, I got "job failed" with the following error message:

listen-3.2.1 requires ruby version >= 2.2.7, ~> 2.2, which is incompatible with
the current version, ruby 3.0.0p0

I then changed the ruby image in .gitlab-ci.yml from ruby:latest to ruby:2 and tried again. That did the trick, and the CI build now passes, and the page gets deployed as expected.

Same problem here! Thanks for sharing the fix. Worked for me as well.
