Not sure if relevant, but here goes anyway. This is a fresh v60 install on a new Ubuntu 22 LTS. I noticed some messages here and there during the install:
sudo: unable to resolve host box.abc.com: Temporary failure in name resolution
What seems to fix it (or at least the message does not show anymore ) I got from here.
In a nutshell, find the hostname with
cat /etc/hostname and add a line in
and add the line with 127.0.1.1 and add the hostname as above
# /etc/hosts 127.0.0.1 localhost 127.0.1.1 box.abc.com # The following lines are desirable for IPv6 capable hosts ::1 localhost ip6-localhost ip6-loopback ff02::1 ip6-allnodes ff02::2 ip6-allrouters
