Hello
last year I put vanilla ubuntu 20.04 onto a neighbours windows vista laptop.
All went well till about January this year, when it upgraded to HWE kernel 5.8, which wouldn't boot on his old machine.
Following a thread in this forum (which I can't now find) I got him back on to 5.4 GA kernel series. Installing linux-generic and removing linux-generic-hwe-20.04 was part of the solution I think, but there was more that I've forgotten.
All was well until a few weeks ago, when HWE kernel 5.11 was installed during an update, and won't boot.
Kernel 5.4 is still there, so I can get him booted using advanced options, but at next boot it tries to use 5.11 again and hangs. I think I need to completely remove HWE.
I tried
Code:
sudo apt remove linux-{image,headers}-generic-hwe-20.04
picked up from an askubuntu post.
This didn't fix matters. I then tried to remove the 5.11 kernels using synaptic, but it wants to install an unsigned version of the same kernel at the same time as removing, which doesn't seem to me likely to help.
Any guidance much appreciated. Thanks
