I'm getting the same bug with the release version of Natty (11.04) so with ecryptfs-utils 87-0ubuntu0.
I got the problem originally by logging out and logging back in without rebooting (which is what I usually do since I very rarely reboot/shutdown my machine). Here's a terminal listing with most of the answers what were asked of the original poster: username1@mybox:~$ ls Private/ [some private files] username1@mybox:~$ ls -alF .ecryptfs/ total 24 drwx------ 2 username1 username1 4096 2009-04-23 15:22 ./ drwxr-xr-x 137 username1 username1 12288 2011-04-29 11:49 ../ -rw-r--r-- 1 username1 username1 0 2009-03-23 16:35 auto-mount -rw-r--r-- 1 username1 username1 0 2009-03-23 16:35 auto-umount -rw-r--r-- 1 username1 username1 17 2009-03-23 16:35 Private.sig -r-------- 1 username1 username1 48 2009-03-23 16:35 wrapped-passphrase -rw-r--r-- 1 username1 username1 0 2009-04-23 15:22 .wrapped-passphrase.recorded username1@mybox:~$ keyctl list @u 2 keys in keyring: 899674517: --alswrv 1000 0 user: 31bb03a50a74ed60 979231033: --alswrv 1000 0 user: a637b5831fc648bc username1@mybox:~$ ecryptfs-umount-private username1@mybox:~$ keyctl list @u 1 key in keyring: 899674517: --alswrv 1000 0 user: 31bb03a50a74ed60 username1@mybox:~$ ecryptfs-mount-private Enter your login passphrase: Inserted auth tok with sig [31bb03a50a74ed60] into the user session keyring keyctl_search: Required key not available Perhaps try the interactive 'ecryptfs-mount-private' username1@mybox:~$ keyctl list @u 1 key in keyring: 899674517: --alswrv 1000 0 user: 31bb03a50a74ed60 username1@mybox:~$ cat .ecryptfs/Private.sig a637b5831fc648bc username1@mybox:~$ ls Private/ Access-Your-Private-Data.desktop README.txt username1@mybox:~$ keyctl clear @u username1@mybox:~$ ecryptfs-mount-private Enter your login passphrase: Inserted auth tok with sig [a637b5831fc648bc] into the user session keyring username1@mybox:~$ ls Private/ [some private files] Calling "keyctl clear @u" before calling "ecryptfs-mount-private" allows the directory to be mounted correctly... but I can't really do that during boot-up. :) Thanks. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/725862 Title: Can’t ecryptfs-mount-private after ecryptfs-umount-private -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
