Hello - I saw your bug report by searching GitHub for people running into trouble with pip 20.3, and figured I could mention here a useful troubleshooting and workaround tip from the documentation: If you need a workaround while you’re fixing the root cause of this problem, you can choose the old resolver behavior using the flag --use-deprecated=legacy-resolver. This will work until we release pip 21.0 (see Deprecation timeline).

Any update on fixing the metadata?? Seems like this would be an easy fix. All of the packages above 1.1.4 are messed up.
