Unfortunately, there is currently no way for system-cleaner to know which packages are obsolete (because they are no longer available via apt-get), and which ones are third-party packages installed outside of apt. Thus the bug is valid, but we can't fix it for now.
I discussed this with Michael Vogt. We'll work on changing libapt after intrepid to make this distinction possible in the future. ** Changed in: system-cleaner (Ubuntu) Status: New => Confirmed -- System cleaner removes explicitly installed third-party packages https://bugs.launchpad.net/bugs/285746 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
