sudo apt install ruby-factory-girl resolved this issue

Another missing dependency issue was resolved via:
sudo apt install rails-controller-testing

Status changed to 'Confirmed' because the bug affects multiple users.

Not exactly the same but I'm not shure to report it here and avoid duplicates:

1) After a apt upgrade today redmine fails to install complaining

2) going to /usr/share/redmine and trying "bundle install" fails too:

I've found the fix that helped at https://stackoverflow.com/a/40672309/3791488
