EDIT 1: I reinstalled 16.04 having booted through the CD but with the HDD installed, now I can read the "readme.txt" and I can click on the "access-your-private-data.desktop" and it seems to run for a few minutes without a window opening and then it stops. When I try running sudo ecryptfs-recover-private I get
INFO: Searching for encrypted private directories (this might take a while)...
find: ‘/run/user/1000/gvfs’: Permission denied
I have a Lenovo E540 (i7) with a 16GB SSD and 1TB HDD. I had the system and swap on the SSD and my data (/home) on the HDD. I tried updating from 14.04 to 16.04. I got asked to confirm the driver EULA but I couldn't select the "OK". I quit the installation. After trying to boot up all I got was an empty screen. I created a 16.04 live cd on a different machine and booted up with that. I removed my hdd prior to this because I didn't want to risk loosing any data. After the installation I shut the notebook down and installed the HDD. I booted up and my HDD appears as a volume and when opened there's two files "access-your-private-data.desktop" "readme.txt" neither of which I can open. I had all my files on the HDD, please help me.
