On cloudlab this works properly. Which machine are you trying this on? Also, what is the output when not using try for the same commands.
from try.
I only get this issue when running on Ubuntu 22
, even on Cloudlab. It should have to do with the kernel version.
from try.
Oh, I see, maybe @ericzty could help you to run it on a specific kernel version to figure out exactly what the problem is and when it happens?
from try.
The issue is with the DNS, since /etc/resolv.conf is a link on that ubuntu system (/run/systemd/resolve/stub-resolv.conf), when in Overlayfs the link broke. The issue can be fixed by adding the following to the innermost shell script in try.
rm /etc/resolv.conf
echo "nameserver 1.1.1.1" > /etc/resolv.conf
Another solution that cbuildrt used is to mount the resolv.conf over from the host filesystem, that is probably a better approach.
from try.
Closing this issue since it has nothing to do with the network
from try.
