I tried the install with other kernels too: 5.4.8 and and 5.4.

This is fixed upstream, but the Ubuntu package is old. Maybe somebody can do something about this.

[Jason A. Donenfeld (zx2c4)]

The kernel team can backport things need be.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1858807

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.
