I am trying to reinstall, but I want to backup my encrypted home first, so I booted up from a live CD, mounted the hard drive, ran
sudo ecryptfs-recover-private <home directory here> and it asked for my passphrase.
I entered it, said it was successful and mounted it it in "/tmp/ecryptfs.somethingsomething" . I go there, using a root nautilus, and double click on the .desktop entry, and it just spawns a terminal window that instantly vanishes.
I checked the readme file and it says that its running
ecryptfs-mount-private, so when I run that in terminal myself, it says "ERROR: Encrypted private directory is not setup properly".
I've googled around and cannot find an answer, since it tells you to recover it using ecryptfs-recover-private, but that obviously isn't' working...
