Ok, symlink '/usr/bin/abrowser' points to /usr/bin/firefox which points to my own startup script.
So fixed with: sudo mv /usr/bin/firefox{,.custom} sudo mv /usr/bin/firefox.original /usr/bin/firefox Also set the default browsers to chromium with: sudo update-alternatives --config x-www-browser sudo update-alternatives --config gnome-www-browser to avoid starting the old firefox version inadvertently (which always causes problems). I will also have to set the BROWSER variable in .bashrc correctly. I might uninstall the firefox package completely or use ubuntuzilla instead. ** Changed in: firefox (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/842420 Title: package firefox 3.6.20+build1+nobinonly-0ubuntu0.10.04.1 failed to install/upgrade: malsukcesis legi staton (dereference) de ekzistanta symlink '/usr/bin/abrowser': Permission denied To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/842420/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
