Hello Joel
This means something went wrong- It really depends on what went wrong- but my directions try to fix it- Yes, If you can get into your system (even with old kernel) use the commands to try to fix it.
Understood … it is going to be the latest action
If you can get into your system with an older kernel - It would be smart to first save your important files just in case.
Yes, it is the primary and main action
Side note- do you have virtual box installed? If you do, that might be the problem- see this post here ubuntu-upgrade-issue-6-14-0-37-generic-to-6-17-0-14-generic-kernel
Yes, as another few laptops with Ubuntu too, where for one of them was update/upgraded (apt) and works normal
Thanks for the support to all
