Hi, Mostly, these errors occur when gems are updated on rubygems.org.
The last gem affected was "activesupport", the issue is explained in the PR: https://github.com/rock-core/package_set/pull/71 "autorespawn", indeed requires ruby 2.1 https://rubygems.org/gems/autorespawn Normally, to solve the issue, you could install the autorespawn gem manually in the correct version BEFORE you do the autoproj update. But all versions of autorespawn require ruby 2.1 :-( so $> gem install autorespawn -v 0.4.1 won't work. $> autoproj show autorespawn tells that the only package that requires it is "tools/roby", where it is listed as optional, so you can remove the line from tools/roby/manifest.xml as a quick fix.
