Thanks a lot! This actually works! I managed to install the livecd this way. I will test to see if the changes are kept after a restart.
For others facing the same issue just do the following as per the bug report posted by django
> What I have to do is go and shutdown systemd-resolved (sudo service systemd-resolved stop) and edit /etc/resolv.conf to point to 192.168.1.1 (my router) instead of 127.0.0.53.
