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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1852521 Title: Unable to boot "Gave up waiting for root device" for kernel version 5.3.0-19 & 5.3.0-22 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1852521/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
