Since they are loadable kernel modules a DKMS RealTek driver
should have no effect on a system without RealTek hardware.
(since the driver would never be loaded)

"An essential feature of DKMS is that it automatically recompiles all DKMS modules if a new kernel version is installed. This allows drivers and devices outside of the mainline kernel to continue working after a Linux kernel upgrade"

Some of these things were not well known and understood when 2.91 was released

PCW post=307735 userid=481This brings up the question is why in the world is ethtool not included in the
LinuxCNC distribution (plus the RT8168 DKMS driver should be as well)

These affect all LinuxCNC Ethernet connected motion devices, not just Mesa

You can send a PR adding ethtool to here github.com/LinuxCNC/linuxcnc-live-build/...sts/desktop.list#L49

The R8168-dkms driver is a bit of a funny one. Its excluded from the default kernel. I suspect the reason is political. I suspect it includes Realtek binaries so not technically open source. But where do you stop? What about the R8125dkms driver many of the recent  micro PCs like the Odroid H3 need?

Plus I am not sure the dkms drivers are benign where no realtek hardware is installed and it then needs compiling on every kernel upgrade

I've heard that ethtools been replaced by ip but AFAIK ip
does not have low level driver control options so cannot
change IRQ coalescing for example.

Just saying that regardless of distribution used, a LinuxCNC
ISO should include it.

Just checked, not included in Mint 22.

Find a USB-wireless dongle and connect to internet.

ip a
 

My computer is not connected to the internet and has no wifi should I connect to the internet and try again? I used a cable to do the installation and then I disconnected it to connect the 7i76e.

Yes, looks like you have no network connectivity.

What does

ip a

report

On your screenshot, it clearly states to do
sudo apt-get update
and try again
Although, this being a networking issue, i have to ask:
-how is the PC wired to internet?
-If wired through cable, did you revert back the network settings?

 

OK so ethtool is not installed

sudo apt-get install ethtool

please let me know where to find instructions on how to start a cut in the middle of the file so at least cut recovery is simpler. 

 

  Run From Line allows starting from almost anywhere in a cut file.

Try

locate ethtool

to see if its installed

if it is found, you may need to give the complete path

if it's not installed you will need to install ethtool

sudo apt-get install ethtool
