Update: I have nailed down the issue. I have root's umask set to 027 When I run aptitude remove ... as root this results in the file /var/lib/apt/extended_states being recreated using that umask which then makes update-manager crash since it cannot read said file.
Possible solutions: 1) require root's umask to allow read access to everyone (BAD) or 2) modify aptitude to create that file world readable (BAD) or 3) make update-manager use sudo (or equiv) to read that file (it must use sudo somehow to do the updates anyway) To recreate: set root's umask to 027 and run aptitude remove xxx from command line as root then launch update-manager. -- [feisty] [apt] command line apt-get/aptitude breaks update-manager https://launchpad.net/bugs/74190 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
