Hi there @biff , I’m also having problems with updating from my 43.20260106 release (but with Bluefin, see here https://universal-blue.discourse.group/t/cant-update-from-bluefin-gts-42-20260106-upwards-bug-kernel-null-pointer-dereference/11585). I’m suspecting something related to my AMD graphics card. Do you have one as well? What (temporarily) worked for me is rebasing to the latest branch (latest-43.20260131.1). Maybe worth a try for you? Good luck.
