I've updated the config table to have consolidation/log and psr/log values.

🤔 I added "consolidation/log": ">=3" to my conflict, but then Drupal 10 was downgraded to alpha5.

I forgot about this. consolidation/log removed Consolidation\Log\ConsoleLogLevel in 3.x. Drush needs to stop using it that constant, and define its own success constant instead. I was going to make a PR, but I've been busy.

[mglaman]

I see https://www.drupal.org/project/drupal/releases/10.0.0-alpha6, this bumped to psr/log 3. Only consolidation/log allows 3 of psr/log

[greg-1-anderson]

Yeah, Drush adopted consolidation/log ^3 some time ago, but erroneously kept using the removed constant Consolidation\Log\ConsoleLogLevel. Drupal was holing Drush back to consolidation/log ^2, so no one noticed the mistake.

[greg-1-anderson]

The tests seem to pass despite the error. 🤷

Perfect @greg-1-anderson and @weitzman, Drupal 10 now installs nicely with the new Drush 11.2.0.
