Error: process_cmd failed: invalid command name "::registry::entry976"

When upgrading outdated ports after upgrading from High Sierra to Catalina (without performing the complete uninstall and reinstall dance of wiki:Migration), I am seeing errors like this:

This seems to happen only for those ports whose version, revision and variants exactly matched the previously installed one. It didn't happen, for example, for findutils, which had been installed with universal before but not now (since universal isn't possible on Catalina).

In 85fd4d52b878a1ebc3f85649ebc894a65bbaf97d/macports-base (master):

Don't close registry ref in portinstall

The way we use the registry, this just isn't safe without ref counting.

See: #64028

[jmroot (Joshua Root)]

Try with that.

Thanks for looking into it! But that doesn't appear to have fixed it:

Perhaps some output from debug mode helps narrow this down:

Try now, I think this was specific to using -u.

[ryandesign (Ryan Carsten Schmidt)]

I think this works! Thanks so much. I would never have found that.
