The error message suggests a bug was in the perl Getopt/Long.pm module. For example, it might have been locally modified. In any case, this bug was filed against apache2 version 2.2 but all supported releases of Ubuntu are on apache 2.4, so this is unlikely to still be relevant.
I'm closing the bug as expired - if it can still be reproduced on current Ubuntu releases, please re-file. ** Changed in: apache2 (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/981647 Title: package apache2.2-common 2.2.22-1ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 255 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apache2/+bug/981647/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
