Bug Description

Ubuntu cannot boot if using kernel version 5.3.0-19 & 5.3.0-22.

However, kernel version 5.3.0-18 works fine.

The root disk is encrypted. When booting with 5.3.0-18, a passsphrase input field is displayed during boot. However, such an input field does not appear in 5.3.0-19 & 5.3.0-22, which eventually leads to time out and the boot failed.

Additional information: When I execute `sudo update-initramfs -c -k 5.3.0-22-generic`

It shows the following:

> update-initramfs: Generating /boot/initrd.img-5.3.0-22-generic
> cryptsetup: WARNING: Skipping root target nvme0n1p5_crypt: uses a key file

I feel that the message about the root partition (nvme0n1p5_crypt) using a key file might suggest something wrong? Because actually I didn't use a key file for the root partition, instead only a passphrase is used.

Thanks for the report, Shaform. There are a few other bug reports against 5.3.0-22 and we're trying to understand if there's a common link. It looks like you're using LUKS/dm-crypt to do full disk encryption of your root partition so we're waiting to hear if that's common throughout the other reports. Thanks again!

It seems that after I performed certain updates, I could not even boot the system with 5.3.0-18 kernel now, which seems to suggest the problem might not originate from the kernel itself.

I did some investigation. It seems that in /etc/crypttab, the third column of the encrypted disk does points to a key file, and the content of the key file is the passphrase.

Not sure why this is created, but I've previously used Ubuntu's disk utility to change the passphrase of my root disk, maybe this is related.

Anyway, I changed the third column to `none` and manually remove the key file. Finally, I execute update-initramfs again and now the system become bootable even with the latest kernel.

Marking as invalid, as this was not related to the TPM or module signing issues we have seen, and the reporter found the problem on crypttab.

Thank you.
Cascardo.
