I have not updated my Ubuntu 18.04 for a long time.
today I have run
sudo apt update && sudo apt upgrade
after this I did
sudo update-grub that gave below the result.

I found that 4.15.0-42 is greater, and 34 is far from 42,
I want to keep 41 as the secondary option next to 42.
Is it possible to install it replacing 34 in my case?
