I had this issue with sound Only "Dummy output" (sound) in Ubuntu 20.04 after reboot - Broken driver / module after a reboot.
I was missing package
Now I rebooted again (I
am not sure think I know if I also rebooted at some point in between), and I had no sound or wifi.
I checked and now I have kernel
5.4.0-42.46, and I didn't have
So I guessed there was an automatic kernel update (I don't recall doing it myself), without installing that package, waiting for me to reboot and suffer from the missing package.
My questions are:
- Why would an automatic kernel update not install
- Can I configure my system to have the package installed whenever an update takes place?
