Seems that apparmor is avoiding firefox access some files. It is strange because I have one user where firefox just runs and another where it does not.
I've seen that I had apparmor enforced for firefox: $ sudo cat /sys/kernel/security/apparmor/profiles [...] /usr/lib/firefox-3.5.*/firefox (enforce) [...] And I've changed to complain (which should be the default on Karmic, and I don't know why I had enforce): $ sudo aa-complain /etc/apparmor.d/usr.bin.firefox-3.5 Setting /etc/apparmor.d/usr.bin.firefox-3.5 to complain mode. -- firefox reports "lock: permission denied"; doesn't start. https://bugs.launchpad.net/bugs/430250 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
