I would like to know what this means and how it can be solved. I ran the following lines:

sudo apt-get update

sudo apt-get install

How can it be solved?

Solution

I suggest that you update linux-firmware to version 1.173. Please open a terminal and do:

wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.173_all.deb
sudo dpkg -i linux-firmware*.deb

Reboot and check if the error is resolved:

dmesg | grep -i firm

Please edit your question to show the result of the terminal command: sudo dpkg -s linux-firmware | grep Version Welcome to Ask Ubuntu.

sudo dpkg -s linux-firmware | grep Version Version: 1.157.20

Ignore it. It's not an issue.

You don't even know if he needs those drivers.

@KenSharp I do know this: his system complains about it, my system, also using an i915 video device, does not. The linux-firmware package included with Ubuntu 18.04 is version 1.173 which includes those exact files: packages.ubuntu.com/bionic/all/linux-firmware/filelist Finally, I am quite confident that after the proposed solution is implemented, the warnings will no longer appear.

My system complains and doesn't use i915. So like I said: you have no idea. You're making assumptions and wasting the user's time installing unnecessary packages.
