I'm in the process of preparing a Linux laptop for the parents so this weekend I upgraded a fresh 23.10 to 24.04 and had some issues I solved that I'd like to share:
1. The nl.archive.ubuntu.com mirror seems to choke on traffic now and then, breaking the do-release-upgrade and resulting in a previous state. 2. Once I had to manually exit do-release-upgrade I was left in a partly upgraded state, so I had to finish using apt dist-upgrade, apt autoremove, which worked fine once I had replaced all the original nl.archive.ubuntu.com references in the sources.list file to archive.ubuntu.com. 3. After rebooting, I was confronted with the black screen I have read about on some fora (reddit) by now. I was able to boot into grub using shift and booting the old kernel was possible. Also booting the new one in recovery was possible and from there starting sddm was also no problem. It turned out there were some i915/xe kms problems(race?). nomodeset kernel option helped, but eventually I added i915 and xe to the initramfs modules and had a booting system with kms again. Hope this helps. Martin -- If 'but' was any useful, it would be a logic operator
