linux firmware errors

After an update. This was kubuntu 20.04. Output from the updater:

Setting up linux-firmware (1.187.17) ...update-initramfs: Generating /boot/initrd.img-5.11.0-37-generic 

W: Possible missing firmware /lib/firmware/i915/skl_guc_49.0.1.bin for module i915 

W: Possible missing firmware /lib/firmware/i915/bxt_guc_49.0.1.bin for module i915

So there's missing bits. Let's grab the latest firmware and install.

get the kernel firmware:

cd ~/
git clone https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git

go to the firmware directory:

cd /lib/firmware

backup the existing firmware:

sudo mv i915 i915.orig 

then copy the new firmmware to the same directory (still in /lib/firmware): 

sudo cp -r ~/linux-firmware/i915/ . 

then:

 

sudo update-initramfs -u -k all
