System won't start after update is installed

ph flag

I updated my Kubuntu from 21.04 to 22.04 and then updated it. Here is a screenshot with the list of updates:

enter image description here

It installs everything and then demands to restart. When I'm trying to reboot the system it just stuck on motherboard logo. I had to restore the system using timeshift

What should I do to update, or should I skip these updates altogether somehow?

----- Update 04.03.2023 ----- Today I tried to start system after shut down and it stuck on the same motherboard logo. I didn't even install any updates before this. However

However, as user535733 suggested, I booted from USB drive and run boot-repair. The only thing that did is allowed me to select OS version before going to the same motherboard logo. Had to restore system from Timeshift backup again

@matigo Ok, I'll try that. Though `22.04` is latest LTS version, so it is strange it is considered EOL release

22.04 is fine. 21.04 is the EOL release

@matigo I updated to `22.04` successfully, but later I updated modules from software update center (Discover on kubuntu), the list is on the screenshot. And after that it asked me to reboot and just stuck on motherboard logo screen

@guiverc I did not upgrade my system using `sudo do-release-upgrade` command, I just installed a new version `22.04` using usb boot drive

"*When I'm trying to reboot the system it just stuck on motherboard logo*" suggests a problem with GRUB. Read your upgrade output carefully for any errors. After the upgrade, try boot-repair.

It seems that the issue was solved by executing the following steps:

  • Updated grub: sudo update-grub
  • Installed all the updates excluding UEFI dbx
  • Installed UEFI dbx with sudo fwupdmgr update
  • Ubuntu started normally after reboot.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
