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:

  1. open you home-> on rifgt side menu select " show hidden files"
  2. You will able to see .ghcup folder
  3. open .ghcup->cache
  4. crate a file named ghcup-0.0.7.yaml
