I was able to reproduce it in ubuntu precise: pcmanfm: 0.9.10-0ubuntu2 udisks: 1.0.4-5ubuntu2 policykit-1: 0.104-1
To test it: 1.- Install ubuntu minimal 2.- install pcmanfm and add gvfs support $ sudo apt-get install pcmanfm gvfs gvfs-common gvfs-daemons gvfs-fuse gvfs-libs libatasmart4 libdevmapper-event1.02.1 libgdu0 libgnome-keyring-common libgnome-keyring0 libgudev-1.0-0 liblvm2app2.2 libsgutils2-2 udisks 3.- run pcmanfm and you'll notice udisks needs and doesn't have as a dependency policykit-1 $ sudo apt-get install policykit-1 4.- run again pcmanfm (once policykit-1 is installed) and try to mount an usb, you'll face the "Not authorized" dialog 5- create /etc/polkit-1/localauthority/50-local.d/55-storage.pkla with the following content: [Storage Permissions] Identity=unix-group:plugdev Action=org.freedesktop.udisks.filesystem-mount;org.freedesktop.udisks.drive-eject;org.freedesktop.udisks.drive-detach;org.freedesktop.udisks.luks-unlock;org.freedesktop.udisks.inhibit-polling;org.freedesktop.udisks.drive-set-spindown ResultAny=yes ResultActive=yes ResultInactive=no 6- add yourself to the plugdev group $ usermod -a -G plugdev your-username 7- pcmanfm will automount usb disks Even when exist a workaround, pcmanfm will termine randomly while umounting those disks -------------------------------------------------- Ubuntu Bug Squad volunteer triager http://wiki.ubuntu.com/BugSquad -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/600575 Title: Error msg "Not Authorized" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/policykit-1/+bug/600575/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
