I had Ubuntu 18 before and I reinstalled Ubunto 20.04 on / partition. I didn't change /home partition during the installation process. I set the same username and. password I had before.

When I try to login to Ubuntu I choose my account, type a password. I see a black screen and I see the log in page again without any error message or something. I googled it and it looks like "login loop error".

On the login screen, I switched to the console mode ([Alt] + [Ctrl] + [F3]) and successfully logged in.

I executed ls -la in my home directory and I see only few items:

Access-Your-Private-Data.desktop -> /usr/share/ecryptfs-utils/encryptfs-mount-provate.desktop
.encryptfs -> /home/.encryptfs/szymon/.encryptfs
.Private -> /home/.encryptfs/szymon/.Private
README.txt -> /usr/share/encryptfs-utils/mount-private.txt

I think the problem here is the lack of mounted encrypted /home partition. Is that a correct statement?

How to fix that?

  • Did you encrypt /home during install of 18.04 or after install?

  • I don't remember but during installation (I think)

  • Think that might be the problem. 20.04 was not made aware of encrypted partition. 20.04 was new install, not upgraded? This is as far as I can help. Will need better people to help from now.

Ok, I solved the issue :)

I've logged in to the system in a console hidden behind [Ctrl] + [Alt] + [F3]. Next I updated system and installed cryptsetup and ecryptfs-mount-private.

Next, I ran ecryptfs-mount-private command, provided a password to the encrypted /home partition and that's all.

After rebooting the partition was already mounted.

  • Actually you just need to have package ecryptfs-utils installed and everything else will just work automatically. I don't know why the Ubuntu upgrade process is not smart enough to automatically install this package if your system contains an encrypted home directory using ecryptfs. I think this worked automatically during Ubuntu 16.04 -> 18.04 upgrade but it failed to work with Ubuntu 18.04 -> Ubuntu 20.04 upgrade... Dec 19, 2022 at 12:55
