Hi Richard, Ben had pointed out this issue in https://mail.haskell.org/pipermail/ghc-devs/2020-June/019000.html
On my system I used the command ssh-keygen -f "/home/simon/.ssh/known_hosts" -R gitlab.haskell.org to remove the problematic key. The next `git pull` then included a prompt to add the new key.
