Dssl2 Installation Issues

raco pkg install dssl2

I've recently updated racket from 7.8.2 to 7.9.1 when updating my system. Upon running any dssl2 script, I get:

standard-module-name-resolver: collection not found
  for module path: dssl2/lang/reader
  collection: "dssl2/lang"
  in collection directories:
   /home/marko/.racket/7.9/collects
   /usr/share/racket/collects
   ... [161 additional linked and package directories]

I've tried running raco pkg install dssl2, which threw:

Resolving "dssl2" via https://download.racket-lang.org/releases/7.9/catalog/
raco pkg install: cannot find package on catalogs
  package: dssl2

curl https://download.racket-lang.org/releases/7.9/catalog/ gives a text/html 404.

This might be a racket catalog issue, but I've skimmed their package catalog on GitHub (not sure if this is the right place), without any results. I've tried running:

grep -r -i dssl2 .
grep -r -i "jesse\.tov" .
grep -r -i northwestern .

where cwd is the master branch of the release catalog, commit adadb82, with no matches.

raco pkg install -t github tov/dssl2

raco pkg install -t github tov/dssl2 and raco pkg install https://github.com/tov/dssl2.git also don't work, being unhappy with the master branch name change to main. The error thrown is:

Querying Git references for dssl2 at git://github.com/tov/dssl2

I did get things to work by manually cloning dssl2 manually and manually installing it with raco, but, more importantly I checked whether DrRacket would install dssl2 well (as most people wouldn't probably know how to manually clone repos and would just follow the guide off the README) and it didn't, throwing the same error.

I suggest leaving the master branch name as a secondary branch until racket fixes their master-referring code.
