apache2-mpm-worker is recommended by trac (through 'provides'): $ apt-cache show trac | grep Recommends Recommends: apache2 | httpd, ... $ apt-cache show apache2-mpm-worker | grep Provides Provides: apache2, apache2-mpm, httpd, httpd-cgi
so it is expected that having trac installed prevents apache2-mpm-worker from being removed. Same situation with bsd-mailx, etc.: $ apt-cache show bsd-mailx | grep Provides Provides: mail-reader, mailx ** Changed in: aptitude (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/217585 Title: aptitude::Delete-Unused behaves incorrectly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/aptitude/+bug/217585/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
