The problem is because of file /etc/apache2/conf.d/phppgadmin.save that you have created. It prevents apache to start. Apache must be properly set up before one can install phpphadmin.
Logs show: Syntax error on line 10 of /etc/apache2/conf.d/phppgadmin.save: The specified network mask is invalid. ** Changed in: phppgadmin (Ubuntu) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1193453 Title: package phppgadmin 5.0.3-1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/phppgadmin/+bug/1193453/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
