I'mm running Ubuntu 18.04. I'm having issues connecting to the Internet after an install of Red Hat Code Ready Containers which did something with dnsmasq. There was a workaround posted here, but I no longer want to use CRC. Having reverted the changes that were advised in that blogpost my internet still isn't working. When I start my laptop, the internet icon appears as an '?' and there is no connection. The systemd resolv.conf doesn't seem to be able to find a DNS server In /etc/resolv.conf it says:
# No DNS servers known.
Can someone advise on how to get internet connection working as Ubuntu intended?
