I have tried everything. Have given up.
Pausing the autoupdates for one week at a time - then when it unpauses I give it a try - watch it go (slooowly) up to 8% for then to tell me my pretty new hp elitebook g10 pro with win11 is not good enough for win11 and I should go buy a new laptop - then I sigh heavily and pauses the updates once again for one week...
I will buy myself a cake to celebrate the day this update actually works.
