Ruby installation fails on Ubuntu 2004

[AHuusom]

Ubuntu 2004 fails at the same spots when run from 2 different computers.
I cannot troubleshoot this as my linux skills aren't that great.

@AHuusom thanks for reporting! We've already started the investigation a few hours ago. It seems that the root cause is in the updated rdoc gem (6.3.0->6.3.1), which is used for fastlane.

The issue in the Fastlane repo
fastlane/fastlane#18642

@AHuusom we've made a workaround #3308. Please pull the latest main and try one more time.

Hi @miketimofeev.
This workaround seems to be working.
Thanks 👍
