Hello,
I launched a Multipass instance with:
multipass launch -c 6 -m 10G -d 50G --name markTest
Then inside it e.g a git clone fails or apt update fails:
git clone https://github.com/cvmfs/cvmfs.git
Cloning into ‘cvmfs’…
fatal: unable to access ‘https://github.com/cvmfs/cvmfs.git/’: gnutls_handshake() failed: The TLS connection was non-properly terminated.
OR
sudo apt update
Err:1 http://ports.ubuntu.com/ubuntu-ports focal InRelease

I worked through:
and seem to get all the expected output, so am at a loss as to how further diagnose the issue. Do you have any suggestions?
Here is the output I get from the suggested diagnostic tests inside the instance (accessed via “multipass shell markTest”)

Then locally on my Mac I checked whilst the instance is running in another terminal:
sudo lsof -iTCP:53 -iUDP:53 -n -P
