Re: Installation, Debian 12, iMac G5, USB thumb drive => “Your installation media couldn’t be mounted. “
Hey Joe,
If you want to continue troubleshooting your built-in Ethernet, try:
sudo ip link set enP1p3s15f0 up
sudo dhclient
then:
ip link show enP1p3s15f0
If it still shows NO-CARRIER, this could mean no cable is plugged in or
driver/firmware issue.
Try: dmesg | grep -i eth
or
dmesg | grep enP1p3s15f0
and see if there's any messages about the kernel complaining about
firmware.
