Can't access the encrypted home directory

[Jacks0n]

Hi,

I tried upgrading to 10.04, and now when it boots it just goes into a grub2 terminal and doesn't display a boot menu. I tried re-installing grub2 from the live cd, but that didn't do anything.

I figured if I've hosed the last install I'll install from scratch, but I can't even access my files from the live cd! I did a bit of searching and everyone seems to just encrypt ~/Private, whereas I've encrypted the whole home directory. So much for security...

In the live cd, it has a readme.txt and says to type "ecryptfs-mount-private" to access the files, but it just gives the error "ERROR: Encrypted private directory is not setup properly". What do I do?


Thanks
Jackson

I found a document about it in the Ubuntu wiki: https://help.ubuntu.com/community/EncryptedPrivateDirectory and followed the instructions.
