I recently ungraded my server from 18.04 to 20.04.1. I had to use the "do-release-upgrade -d" command as it refused to see the latest LTS release.
The motherboard is an Asrock X370 Gaming Pro that includes an Aquantia AQC108 5gbps NIC. As long as I've had it, I've been using Marvell's driver for it and had no issues.
I upgraded to 20.04 and now there's issues. So, first I upgraded the kernel using UKUU to 5.4. When I tried to install the Marvell driver I got a message that the included driver in the kernel was newer. Ok, cool - remove the driver from the 5.4 kernel and I removed it from the previous 4.x kernel.
This did not solve the problem. The OS sees the NIC, but will not accept the IP being assigned by my router.
I've tried using ifconfig up/down, restarting - no changes.
Please help! Where do I start with the troubleshooting?
