[Kernel-packages] [Bug 1867026] Re: wifi adapter is missing - wrong iwlwifi firmware
After installing https://people.canonical.com/~acelan/bugs/lp1865829/
the wifi works.
So, this is a problem in the kernel itself, not linux-firmware.
I guess I have to wait for
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1865962to be finished?
Will this fix be updated to kernel 5.3.x (I don't update my kernel very
frequently)?
Thank you
