Public bug reported: I observed on my trusty box that aptitude keeps libqt4-dev even though it is marked as automatically installed and no other package depends on or recommends it.
$ sudo aptitude show libqt4-dev|grep Auto Automatically installed: yes $ aptitude why libqt4-dev i postbooks-updater Depends libqt4-sql-psql i A libqt4-sql-psql Suggests libqt4-dev In other words, there is no package on the system that at least depends on or recommends libqt4-dev to be installed. Since the package is marked as automatically installed aptitude should offer to remove it which for some unknown reason does not happen ** Affects: aptitude (Ubuntu) Importance: Undecided Status: New ** Tags: trusty ** Attachment added: "compressed output of "aptitude -v why libqt4-dev"" https://bugs.launchpad.net/bugs/1401008/+attachment/4277428/+files/libqt4-dev.dependency.log.bz2 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1401008 Title: does not automatically deinstall libqt4-dev when it should To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/aptitude/+bug/1401008/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
