DNS resolution on RPI 12 with Network Manager There was an error when trying to resolve with sites like github after a fresh install and enabling VNC I believe. There was a file in the /etc/nsswitch.conf that had a line that needed to be changed
hosts: files mdns4_minimal [NOTFOUND=return] resolve [!UNAVAIL=return] dns
to
hosts: files dns mdns4_minimal [NOTFOUND=return] resolve [!UNAVAIL=return]
it is a small subtle change, but it was what fixed my issue of being able to git clone repos
