Error: [S-4804]
       Stack failed to construct a build plan.
       
       While constructing the build plan, Stack encountered the following errors:
       
       In the dependencies for ghc-events-analyze-0.2.8:

       needed since ghc-events-analyze is a build target.

This might be due to the necessary dependencies not being available in the stack snapshot? Try cabal, perhaps, to see which dependencies it selects, and then you can selectively add overrides to the stack snapshot. If cabal can't find a build plan, then there really is a dependency issue that might need resolving.

I tried by specifying the missing packages as extra-deps in stack.yaml, but it that, in turn, produced several more errors, at which point, I stopped. It seems the dependencies need to be updated to catch up the the latest LTS.

I took a quick look. I've relaxed the upper bound on optparse-applicative, which was easy, but the upper bound on SVGFonts is currently necessary; version 1.8 introduces a number of breaking changes that would require changing the code, which I don't have time for at the moment. PR welcome :)
