test docker for guest ubuntu:
docker run --rm -it ghcr.io/ggerganov/llama.cpp:full --version

Wow! you know my wifi name.  I redo  all the setting, but docker run insisted to use 127.0.0.53:53 , it's hurting me.  The following is the bash cmd and output:



za@zaasus:~/tmp

$ sudo netplan  apply

za@zaasus:~/tmp

$

# Replace "secondHand" with your actual connection name if it differs

sudo nmcli connection modify "secondHand" ipv4.dns "8.8.8.8 8.8.4.4"

sudo nmcli connection modify "secondHand" ipv4.ignore-auto-dns yes

za@zaasus:~/tmp

$ sudo nmcli connection up "secondHand"

Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/5)
