I used Disks tool to make an image of a partition:
Then tried to mount it with Disk Image Mounter:
I enter my password twice:
Then it fails with this error message:
Unable to mount OLD SYSTEM_DRV
Error mounting /dev/loop1 at /media/endolith/OLD SYSTEM_DRV: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000" "/dev/loop1" "/media/endolith/OLD SYSTEM_DRV"' exited with non-zero exit status 21: ntfs-3g-mount: mount failed: Permission denied
Why is permission denied and how do I fix this?
