Eugen, normally the kernel bot posts the following text but it hasn't done so as the bug report has a status of 'Incomplete' and was initially filed against the installer rather than the kernel:
--- 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 1894860 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'. --- Make sure you update the status even if you can't run the 'apport- collect' command. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1894860 Title: Boot fails with newer kernel Status in linux package in Ubuntu: Incomplete Bug description: I get a "cryptsetup: Waiting for encrypted source device UUID=<UID>" message when trying to boot with kernels 5.4.0-47 and 5.4.0.-45 and then nothing happens pressing ESC displays "Volume group "vgubuntu" not found Cannot process volume group vgubuntu" System was dm-crypt/LUKS encrypted at installation kernel 5.4.0-42 still works ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: ubiquity (not installed) ProcVersionSignature: Ubuntu 5.4.0-42.46-generic 5.4.44 Uname: Linux 5.4.0-42-generic x86_64 ApportVersion: 2.20.11-0ubuntu27.8 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: GNOME Date: Tue Sep 8 16:41:34 2020 InstallCmdLine: BOOT_IMAGE=/casper/vmlinuz file=/cdrom/preseed/ubuntu.seed only-ubiquity quiet splash nomodeset --- InstallationDate: Installed on 2019-10-18 (326 days ago) InstallationMedia: Ubuntu 19.10 "Eoan Ermine" - Release amd64 (20191017) ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=de_DE.UTF-8 SHELL=/bin/bash SourcePackage: ubiquity Symptom: installation UpgradeStatus: Upgraded to focal on 2020-04-27 (134 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1894860/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
