Hello Orvar, You can find pointers to get help for this sort of problem in the Community Support channels:
https://ubuntu.com/support/community-support We use this bug tracker to track bugs in Ubuntu, rather than configuration problems. This helps us to focus on fixing bugs in Ubuntu. If you believe you actually found a bug, then you may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem and explain why you believe this is a bug in Ubuntu rather than a problem specific to your system. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1895156 Title: package postfix 3.4.13-0ubuntu1 failed to install/upgrade: installed postfix package post-installation script subprocess returned error exit status 75 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/postfix/+bug/1895156/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
