Made an account to say that #52 worked for me. After upgrading to Ubuntu 14.04 from 12.04, I had lost sound, the ability to shut down/reboot as a normal user, and the ability to mount external SD cards/hard drives. Did "sudo pam-auth-update --force" and "sudo apt-get remove --purge libpam- ck-connector" as #52 suggested, and after a reboot, everything worked again!
I should say that at this point my pam.d is close, but not identical to, a fresh 14.04 install. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1240336 Title: After release upgrade, the user looses permissions for several basic actions in the system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm/+bug/1240336/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
