The day before I run into the problem I had installed Virtual Machine and Vagrant and everything was fine. When I fired up my computer the next day, I got stuck in a login loop. My next action was go to the command line, easily log in and there was a README file. The file has this message:
THIS DIRECTORY HAS BEEN UNMOUNTED TO PROTECT YOUR DATA.
From the graphical desktop, click on:
"Access Your Private Data"
or
From the command line, run:
ecryptfs-mount-private
Well, then I run ecryptfs-mount-private and it requests me for a login passphrase. The problem is I never set that passphrase. Any idea on how to fix it?
