master: cabal install from hackage broken? #9715
Description
Just built cabal from master 3d3622f and tried in my home directory:
$ cabal v2-install cabal-install-3.10.2.1 --program-suffix=-3.10.2.1
Warning: this is a debug build of cabal-install with assertions enabled.
No cabal.project file or cabal file matching the default glob './*.cabal' was found.
Please create a package description file <pkgname>.cabal or a cabal.project file referencing the packages you want to build.
Looks like installation from hackage is broken in general, e.g. cabal install hangman also fails.
The docs say it should work: https://cabal.readthedocs.io/en/latest/cabal-commands.html#cabal-install
