    I messed up the first command because of a copy/paste but kernel update issues are rare, I have only had one in 6 years but they do happen

    It works!!!! Thank you so much for your expert help and patience! I learned a lot and I am sure that I would not have been able of solving this problem on my own! I must be more careful when upgrading as I must have done something wrong.....

    jeremy31 solved my problem! However, when running 'sudo apt update and sudo apt upgrade' the headers are apparently lost and I
    always have to re-run the below (adjusted for the new kernel having become installed)!
    sudo apt purge backport-iwlwifi-dkms
    sudo apt install --reinstall linux-headers-5.8.0-38-generic linux-modules-extra-5.8.0-38-generic
    Is there a way to make the change permanent so that I can upgrade normally?
    Thanks, D.

    Hi,
    I am sorry, I somewhat messed up this tread answering to something else. Here is the correct one.
    Jeremy31 solved my problem. Thanks again! However, when upgrading the headers are lost and I must re-install them as before.
    How can I arrange that the headers are automatically upgraded as well and not deleted?
    Thanks, D

    Uncle Jeremy may be out for a coffee. He suggests that you do:

    Code:
    sudo apt install linux-headers-generic
    You should be all set.
