Mesa connection issue

It's still giving the unreachable error

looks like there's still an error in your interfaces file

What's in it now?

It looks like it somehow changed.

Maybe you forgot to edit it as root (with sudo)
(since that's your previous file edit)

Ok, the /etc/network/interfaces.d/setup is edited as you instructed. But, I mistakenly edited the /etc/network/interfaces file. What should that file look like?
Still get the unreachable error.

I dont think the setup file should be changed, its the interfaces file that should be changed

Here is my interfaces file:

# interfaces(5) file used by ifup( and ifdown(
auto lo
iface lo inet loopback

auto eno1
iface eno1 inet static
address 10.10.10.100
hardware-irq-coalesce-rx-usecs 0


Note that your Ethenet device name is eth0 not eno1 and you probably don't need the coalesce settings
so you should have something like:

# interfaces(5) file used by ifup( and ifdown(
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 10.10.10.100
