Ubuntu 12.04 Keyring broken "signature not found in user keyring perhaps try the

Question

So, for some reason i cant suddenly log into my main account, so i did alt+ctrl+f1 and saw the message "signature not found in user keyring perhaps try the interactive 'ecryptfs-mount-private'"

I can log into another account such as root without any issue how would i fix this issue?

Solution

This happened to me tonight. It happens when you change your user password, but not your encryption passphrase. They are usually in sync.

To fix this, simply run:

ecryptfs-rewrap-passphrase /home/.ecryptfs/$USER/.ecryptfs/wrapped-passphrase

It will prompt you for your old passphrase, then allow you to enter a new one. Then, you will be able to log in normally.

For me it worked, but only if the new passphrase was the same as the password I set for the user account.

ecryptfs-rewrap-passphrase caused me some troubles. See description unix.stackexchange.com/questions/329661 for your consideration
