After upgrading the v20, I get stuck in a login loop at boot.

[Aaron Iles]

Many others have reported the login boot loop for Ubuntu 20.04 LTS. After trying a number of fixes, the only thing that worked was removing chrome-remote-desktop. Running "sudo apt-get purge chrome-remote-desktop" resolved the issue.

Status changed to 'Confirmed' because the bug affects multiple users.

For me, the issue was (probably) enabling auto-login. Disabling that & deleting some .XConfig file solved it.

The package chrome-remote-desktop is not one provided by the Ubuntu archive and subsequently there is not thing we, the developers of Ubuntu, can do about the issue.
