I ran into this problem on Lubuntu 14.04. On that machine, the user created during the installation had no problem but every other regular users were affected.
The workaround was to join the regular users to the sudo group to please polkit. Since I really wanted those users to be "power less" I also added those sudoer rules: jane ALL=(ALL) !ALL jdoe ALL=(ALL) !ALL -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1240336 Title: After release upgrade, the user looses permissions for several basic actions in the system Status in gdm package in Ubuntu: Triaged Status in lightdm package in Ubuntu: Triaged Status in lxdm package in Ubuntu: Triaged Status in policykit-desktop-privileges package in Ubuntu: Triaged Bug description: HOW TO REPRODUCE: - Upgrade Ubuntu to the next release.
