It seems that the pmount package was not properly installed. Was there an upgrade which was interrupted by any package failure, so that pmount could not be configured properly? Please try
sudo apt-get -f install copy&paste the result here, and then please check that stat -c %a /usr/bin/pmount prints '4754'. Thank you! ** Changed in: pmount (Ubuntu) Status: Unconfirmed => Needs Info -- USB Storage Device (Sony PSP) Fails to Mount as User https://launchpad.net/bugs/60675 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
