--- Comment #2 from Olivier Carton <olivier.carton....@gmail.com> --- Thank you for taking care of it. Here are some more information. If I try to mount using udisk directly with something like "udisksctl mount -b /dev/sdb1", it works. If I add a file /etc/polkit-1/rules.d/10-udisks.rules containing polkit.addRule(function(action, subject) { if (action.id == "org.freedesktop.udisks2.filesystem-mount" && subject.isInGroup("plugdev")) { return "yes"; } }); it solves the problem. This means by the way that the bug is not so annoying but it also shows that the problem comes really from the interaction with polkit. From what you say, this interaction is done by udisk. Is udisk "called" in the way in both scenarios ? However, this trick does not solve the second problem I mentioned. Dolphin still does not start. -- You are receiving this mail because: You are watching all bug changes.
