after I couldn't log in into my old ubuntu instance I've reset the password via instructions in https://askubuntu.com/a/24024/639921
now, after I try to log in it just loops me back to the login screen I think it may be due to the \home being encrypted, because after going to the terminal I'm able to log in correctly, but can't access my files, I see just the Access-Your-Private-Data.desktop and README files
ecryptfs-mount-private asks for a login password, which I lost/reset
I've got a potential ecryptfs passphrase saved, but I'm not sure on how to handle this situation, can I please get some suggestions?
for example: how to update the ecryptfs password using the passphrase?
