Unfortunately I got hit by a major update error 9-Oct. Over 200 packages were pushed for Kubuntu 22.04. It basically bricked my system GUI - but I could use GRUB and get to a console and save the data. Two main errors were visible on the console - #1 was a pci bus error that seems to have been resolved through rebuilding the system from scratch. The second is a UBSAN error that seems to be attributed to virtualbox. I have also posted this over in "ask ubuntu" but very little traction there. Does anyone have any experience with this or know how to resolve it? The error causes the computer hang on boot and will time-out after about 30 seconds or so, the boot continues. Also the system will not "restart" reliably. A full power off then start does work, but the error does not resolve.
Photo attached is from the boot process. Any ideas would be greatly appreciated.
