When I unplugged the ethernet cable from my computer and then connected it back, the PC was not using ipv4 anymore, it uses ipv6 now. For some reason, ipv6 doesn't work and I want to switch back to ipv4. How can I do so?
I am running Ubuntu 20.04.

In network settings, you should be able to choose the IPv6 tab and disable it
