This happened to me again when I did a new clean install of Ubuntu 10.10 (on two different machines with the same problem).
The only workaround that works (for me) is to open two terminal windows and in the first go: sudo blkid to see the UUIDs of all devices. In the second go sudo gedit /etc/fstab and add an additional line for the device(s) that you can't mount. A couple of examples that work for me are: UUID=87b43805-e339-4953-9c9c-328e71c0abdc /media/budisc ext4 users,rw 0 0 UUID=744C979E4C975A26 /media/seagate ntfs users,rw 0 0 Have system/administration/disk utility open at the same time. Mount seems to work once the /etc/fstab file is updated. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to nautilus in ubuntu. https://bugs.launchpad.net/bugs/518533 Title: Unable to mount location Not Authorized after nautilus upgrade -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
