Description

Can't install Craft with existing project config, says No primary site exists - while there is. This happens for me on multiple installations - with one and with multiple sites. But it also succeeds on some installations...

Not able to reproduce this on my end. Can you send your Composer and project config files over to [email protected] so we can test with your setup?

@brandonkelly think I found it already - in migrations/Install.php on line 1063 you are calling ProjectConfigHelper::ensureAllSitesProcessed(). At this point Craft::$app->projectConfig->getIsApplyingYamlChanges() is always false, and thus no sites are processed (changed here: https://github.com/craftcms/cms/commit/6f6ba6241f6f6a67ad479f7a84a5659fb7c55581#diff-100ad843bc151c8d7358da24c6c30545)

Alright, probably just fixed it. Can you update to dev-develop and see if that works for you?

[boboldehampsink]

@brandonkelly thanks, that fixed it :-)

[brandonkelly]

Craft 3.5.13 is out now with that fix.
