Description dE 2013-03-18 05:38:49 UTC

Since my upgrade to kde 4.10.1 (from kde 4.9.5), I cant mount any external media.

Device manager says "cannot mount the following device:" and dolphin says -- 

"An error occurred while accessing external', the system responded: An unspecified error has occurred: Adding read ACL for uid 1000 to `/run/media/de' failed: Operation not supported"

Reproducible: Always

Wont product, I know.

Udisk needed TMPFS_POSIX_ACL in kernel.

Comment 3 Chao Feng 2013-03-22 04:27:00 UTC

It seems a distro issue. The permision of /media is not set properly. See here for  solution.  http://askubuntu.com/questions/202560/cant-mount-any-partition-due-to-usb-adding-read-acl-for-uid-1000-to-media-e

Could you check if the solution works?

Ubuntu appears to have modified udisks to mount to /media instead of /run. Vanilla udisks mount to /run/media/<username>.

My problem was that, the kernel didn't have TMPFS_POSIX_ACL, which hindered operation of the new udev.
