I'm trying to install GHC with ghcup on an windows laptop running an Ubuntu subsystem. I keep getting the same error and I don't even really know what is going wrong. Here are the error messages:

Any ideas on why this is happening and how to fix it?
Judging by this issue on the ghcup repo (it cites the same error as yours), you are using WSL 1, which is not supported. You have to upgrade to WSL 2.
