I upgraded my system from 20.04 (Desktop) to 22.04 (Desktop). I followed the installation of the pop-up screen Do you want to upgrade to 22.04. In the last step, there was a Restart Required, which left me with the blinking screen I took a photo of.

I did not experience any errors of any kind during the installation.

Has anyone seen this kind of error before? And maybe have an idea how I go about fixing it?

The text on the photo1 says:

[0.125709] x86/cpu: VMX (outside TXT) disabled by BIOS

/dev/sda5: clean, 201894/30498816 files, 6244232/121964800 blocks

[20.488414]

  • I haven't used this computer in quite a while so I don't know the details completely of the system that was on there but I'll do my best to state what I think Is correct.

    I'm pretty certain there was a 20.04 (Desktop) on there that I then followed the installer, the thing that pops up "Do you want to upgrade to 22.04", and in the last step there was a "restart required" which ended in this blinking screen.

    No errors I saw throughout the install.

  • I changed the title and question. Hope it's better now! – DSP son Apr 11 '23 at 10:35
  • Usually the statement "Long time not used" leads me to Bios Battery empty. Empty battery can lead to all kind of strange behavior. – Marco Apr 11 '23 at 10:56
  • @Marco, interesting. I did boot this computer up normally yesterday and It was OK with 20.04. Do you believe the BIOS battery could have somehow drained in the process of upgrading the system? – DSP son Apr 11 '23 at 11:02

    So new info on this: I can boot if I go through recovery mode (holding down shift while turning on the computer, going into advanced options, and choosing recovery mode). There I ran dpkg and then just normal boot, and it booted fine, and I can use the machine normally.

    But when I restart it I get the same black screen—blinking this text again.

    Please add additional detail to your question; this is a Q&A site (Question & Answer site) and not a forum. Comments are intended to be only that, comments to the original question, or a prior commentator & not for information from the Original Poster (OP) as that is deemed important detail & belongs in the Question (as it's useful for answers to consider; comments are not considered in answers, as they answer only the question). I realize you're new, but Forums & Q&A sites differ in approach.. Forums require you to read the whole thread; here only the Question matters – guiverc Apr 11 '23 at 11:30

  • Have you tried booting from flash stick with 22.04? Is secure boot disabled? – Mahler Apr 12 '23 at 15:01
