Did you verify the ISO as being perfect? (https://tutorials.ubuntu.com/tutorial/tutorial-how-to-verify-ubuntu#0) and most importantly the write to your installation media (https://tutorials.ubuntu.com/tutorial/tutorial-how-to-verify-ubuntu#0 ; this will fail if you used incorrect or older versions of ISO write programs that cannot deal with the 21.10 ISO) https://ubuntu.com/tutorials/tutorial-create-a-usb-stick-on-ubuntu#1-overview https://ubuntu.com/tutorials/tutorial-create-a-usb-stick-on-macos#1-overview https://ubuntu.com/tutorials/tutorial-create-a-usb-stick-on-windows#1-overview

Ive verified the download, and used both disk creator on ubuntu and latest rufus on windows, both having same error during install attempt.

Fair enough.... If i have problems with booting a device; I tend to boot it on other boxes to verify the write (ie. a somewhat similar box & a very different one); where if it fails to boot on all devices - I blame the write to media (*about 5-8% fail in my experience*) where if it boots on others & only fails on the *first* box - it's specific to the hardware on that *first* box.

Just tested the media on another device (not the same model) with no such issue. I have read of an kernel bug with this thinkpad series, but dont know how to bypass it.

I have managed to fix the issue:

  • In the grub boot menu choose UEFI firmware settings.
  • In there turn off the pad and tracker in the settings. (This by the way will not make them stop working, for some reason.)
  • Restart and install Ubuntu regularly.

What is the pad and tracker exactly? I've the same error I tried TrackPoint and TrackPad.

The same just happened to me after upgrading from the earlier version, groovy gorilla. With a white screen of death in between. Followed this for that.

I managed to get past by choosing an earlier kernel version for ubuntu from the Grub menu -> Ubuntu, with Linux 5.11.0.40-generic

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.
