Well, this is interesting...
Pamac tray indicator said there were some updates. So I went into Pamac Manager to check the AUR setting, and started the update.
Clicked the Detail tab, and watched a bunch of 404 message scroll by. Alarming!!.
Any way the update seemed to do something, and I rebooted.
No network adaptors at all appear anymore. MSM, and lspci show them, but the drivers apparently can't be found, and aren't loaded. (Machine has two gigabit ethernet R8168 ports).
I have no network access from that machine. C
Currently digging through my "drawer of broken dreams" to find my USB wifi adaptor.
After plugging in my WIFI USB Dongle, and trying to connect with Network Manager, the machine froze up. (all USB devices ceased to function) and I had to power cycle the machine.
When it rebooted the R8168 ports were working again. No clue what caused that, or why they stopped working. I then did another update, and found over 200 packages and that all went smoothly.
I declined the AUR gtstreamer packages, and then manually removed them after the update.
