I’ve only seen this issue in 1 scenario. When I changed the hostname and forgot to reboot.

Might it be your case?

Otherwise it might also be an issue in the ./etc/hostname and or /etc/hosts…

check that hots and hostname files match…

sudo nano /etc/hosts
sudo nano /etc/hostname

looks like a dns error

Yep, it was that, shouldn’t be fixed automatically by the institallation?
