I have a new pve install. I would like to tether it to my Samsung S20+ phone for Internet access.

I connect the phone to a USB port on a Dell Optiplex 790 (I know, ancient, but it works very nicely).

lsusb shows this:

Bus 001 Device 004: ID 04e8:6864 Samsung Electronics Co., Ltd GT-I9070 (network tethering, USB Debugging enabled)

which looks like it recognizes the phone without issues.

"ip a" shows the interface with state "down"

"ip link set <enx...> up"

followed by "ip a" shows state UNKNOWN

"dhclient <enx...>" doesn't complain, but pinging google.com gets a "destination net unreachable".

help me out, please.
