If you are running default kernel with your Ubuntu or Linux Mint installation, you probably won’t face this problem during kernel updates because all packages are coming from the official distribution sources. However, if you like to run the newest Linux kernels and update them using
kernel installer, you may get warning
possible missing firmware during the installation.
Few days ago I got this warning on my
Linux Mint 20.3 Una while installing kernel
5.17.7. In most of the cases this warning won’t affect normal functionality of your Linux machine, but if you hate warnings, like I do, here is what you can do. I guess you regularly update your
apt packages, but still new kernels may complain, which further means you may need even newer package. In my case I had to install
linux-firmware package from
, the newest LTS Ubuntu,
Ubuntu 22.04 LTS.
So, first add
jammy repository (temporarily), then fix broken dependencies, install the bleeding edge
linux-firmware and remove the repository if you don’t want to update any other package. You may also want to reinstall your newest kernel and find out that there are no such warnings.
Buy the way, in the meantime kernels
5.7.19 are released, but my Intel
AC 9560 won’t work properly, so I skipped them and wait for some further version to find out if this is fixed or I need to do something about it myself. I may update you about this problem, so let’s stay in touch.
