[xmonad] Problem upgrading xmonad via cabal

Wed Mar 11 23:02:10 UTC 2020

I've also tried upgrading cabal itself and I get the following:

> cabal install Cabal cabal-install
Warning: The install command is a part of the legacy v1 style of cabal
usage.

Please switch to using either the new project style and the new-install
command or the legacy v1-install alias as new-style projects will become the
default in the next version of cabal-install. Please file a bug if you
cannot
replicate a working v1- use case with the new-style commands.

After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: cabal-install, HTTP, base, Cabal,
time, directory, process, template-haskell, hackage-security, unix,
cabal-install:lib
