View Full Version : [ubuntu] Not authorized to perform operation on disks after upgrade

April 25th, 2015, 06:32 PM
After upgrading from 14.10 to 15.04 extra disks have stopped auto-mounting , when I click on a disk in the sidebar of the file manager the error message "Unable to access “DISKNAME” Not authorized to perform operation, the same thing happens for USB disks. I guess it is a permissions problem but i have no idea where to start. Anyone have an idea ?

Does this error happen in a standard or administrator account? I've had this problem accessing extra drives from a standard account but not from an administrative account, so that I had to give permission from the administrator account to allow the standard accounts to access extra drives.

It is an admistrator account. Something must be wrong with the settings for that though. In the user accounts in setting the unlock button is greyed out and adding a user is not possible. Does anyone have a good guide for user administration from the CLI ? Maybe if i cold create a new adminstrator user in the CLI and then set the same permissions for my current user ?
