I updated an old laptop to bookworm - but on reboot the hard-wired
ethernet connection wouldn't work. Trying to manually configure the
networking via
nmcli c edit eth0
appeared to work ('print' gave the right values) BUT networking still
didn't work. Old standby /sbin/ifconfig showed the old/wrong values
even after restarting networking. On finally trying
nmcli c show
it showed not 1 but 2 entries for eth0 - though with different UUIDs.
Attempting to delete/remove the connection entry with the wrong data
simply caused the defective connection entry to be replicated, only now
with yet another UUID. It is this erroneous connection entry that
appears connected to the eth0 device.
Is there some magic I'm missing for setting the ipv4 parameters?
Thanks for any insights!
