 I'm not sure this error is directly caused by the antiquated compiler, but also not sure how to debug this further or work around it either.

+git-annex is still targeting supporting ghc back to 9.0.2, so your old
+ghc should not yet be a problem. However, I don't have any CI left that
+uses such old versions of ghc, so it might break from time to time.
+
+I've fixed this one, which was a missing `import Control.Monad`. Please
+report if you find other build failures.
