I made it installs correctly. Since I had a backup, I decided to reinstall completely from scratch (which didn't work at first...)
And since I don't know what was necessary and what wasn't, here is all I've done to do so: # removed completely (answered yes to database removal) apt remove -y redmine apt autoremove -y # fixed the rake problem for install rm /usr/local/bin/rake # reinstalled apt install redmine service redmine start # it started but as a new install, will now try to restore backup... What I know for sure is the problem is coming from the /usr/local/bin/rake file (which refers to ruby2.3) Should give you a hint on how to fix this ;) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1785502 Title: package redmine 3.4.4-1 failed to install/upgrade: installed redmine package post-installation script subprocess returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/redmine/+bug/1785502/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
