Sorry, two questions: As the system crashes during boot, would apport-collect transmit any logs reflecting the crash, when in fact called after rebooting with the older kernel? How can I trigger apport-collect on a server only installation? Thanks, Joachim

The system is a server type installation running as a virtual machine on Hyper-V, primarily running letsencrypt and nginx. Actually I tried twice, both upgrades left me with a system that doesn´t boot by default. The first iteration was I tried to accept maintainer version for the boot/grub menu, and as that didn´t restart properly, I tried another time, this time keeping my own version. Both upgrades left me with a system that was not booting. With the second upgrade, I experimented a little more. When the system restarts, I am stuck with it doesn´t boot. When I then power off and power on again, I get a boot menu with the options Ubuntu, Advanced options for Ubuntu, and UEFI Firmware Settings. With Advanced I get Ubuntu with various kernel options, with Linux 5.4.0-73-generic w/o recovery mode, and Linux 4.15.0-143-generic w/o recovery mode. The variants with 4.15.0-143 actually work, whereas 5.4.0-73 doesn´t work. I do have some VMs that run 20.04 with kernel 5.4.0-something, thus I assume it is an issue caused by the upgrade or previous installation. Any idea what to look for? I asked this already at https://askubuntu.com/questions/1338236/ubuntu-fails-to-start-by- default-after-upgrade-18-04-to-20-04 and then https://answers.launchpad.net/ubuntu/+question/697332, but didn´t get a response that helped me to resolve the issue.
