3.2.0-85.122 to 3.2.0-85.124 also gets error: df: `/sys/kernel/debug': Function not implemented which I think is being fixed in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1465322 Similar gvfs error is also in trusty 3.13.0-53-generic #89-Ubuntu : df: ‘/run/user/104/gvfs’: Permission denied -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/867806 Title: df -h permission denied error Status in Light Display Manager: New Status in lightdm package in Ubuntu: Confirmed Bug description: Running "df -h" from the cli as a normal user returns: Filesystem Size Used Avail Use% Mounted on /dev/md0 37G 6.6G 29G 19% / udev 796M 8.0K 796M 1% /dev tmpfs 322M 888K 321M 1% /run none 5.0M 0 5.0M 0% /run/lock none 805M 92K 805M 1% /run/shm /dev/sda3 1.8T 265G 1.6T 15% /mnt/d1 /dev/sdb3 1.8T 1.7T 102G 95% /mnt/d2 /dev/sdc3 893G 33M 893G 1% /mnt/d3 df: `/var/lib/lightdm/.gvfs': Permission denied $ running with "su" $ sudo df -h Filesystem Size Used Avail Use% Mounted on /dev/md0 37G 6.6G 29G 19% / udev 796M 8.0K 796M 1% /dev tmpfs 322M 888K 321M 1% /run none 5.0M 0 5.0M 0% /run/lock none 805M 92K 805M 1% /run/shm /dev/sda3 1.8T 265G 1.6T 15% /mnt/d1 /dev/sdb3 1.8T 1.7T 102G 95% /mnt/d2 /dev/sdc3 893G 33M 893G 1% /mnt/d3 $ ProblemType: Bug DistroRelease: Ubuntu 11.10 Package: bash 4.2-0ubuntu4 ProcVersionSignature: Ubuntu 3.0.0-10.16-server 3.0.4 Uname: Linux 3.0.0-10-server x86_64 ApportVersion: 1.23-0ubuntu2 Architecture: amd64 Date: Tue Oct 4 14:17:28 2011 InstallationMedia: Ubuntu-Server 11.04 "Natty Narwhal" - Release amd64 (20110426) ProcEnviron: SHELL=/bin/bash LANG=en_US.UTF-8 SourcePackage: bash UpgradeStatus: Upgraded to oneiric on 2011-09-05 (29 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/lightdm/+bug/867806/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
