Hi, I try to use calibre with Crux 3.1. It starts, but it doesn't 'mount' any devices (e-readers) when started as a normal account. Root is OK. There is following error message: Udisks mount call failed: Traceback (most recent call last): File "site-packages/calibre/devices/usbms/device.py", line 600, in do_mount File "site-packages/calibre/devices/udisks.py", line 180, in mount File "site-packages/calibre/devices/udisks.py", line 133, in mount File "site-packages/dbus/proxies.py", line 145, in __call__ File "site-packages/dbus/connection.py", line 651, in call_blocking DBusException: org.freedesktop.UDisks2.Error.NotAuthorizedCanObtain: Not authorized to perform operation Unable to open device <calibre.devices.kobo.driver.KOBOTOUCH object at 0x7fa4b7ff0dd0> I spent some time working around udisks2, polkit, consolekit, but I think it's time to start from fresh. Could you please share any advices?
