Expectation: Intel AX210 wifi works without having to perform extra steps to
rename/delete files after linux-firmware package updates
--4--
Reality: Intel AX210 wifi does not work without performing extra steps to
rename/delete files after linux-firmware package updates
I have no idea where the .pnvm file is coming from as it is not
present in the files provided by Intel at
https://www.intel.com/content/www/us/en/support/articles/000005511/wireless.html
Please consider removing the .pnvm files from all versions of the
'linux-firmware' package... currently found in these versions:
1 pnvm file - https://packages.ubuntu.com/focal-updates/all/linux-
firmware/filelist
2 pnvm files - https://packages.ubuntu.com/impish/all/linux-
firmware/filelist
The pnvm file is not present in the Ubuntu 2104 (Hirsute) linux-firmware
package and the AX210 wifi works perfectly well on that platform but it fails
to function on 20.04 (Focal), where the pnvm is present, and will likely also
fail in 21.10 (Impish).
