it seems https://docs.joinmastodon.org/administration/installation/#installing-ruby needs be updated to ruby 2.6.5, as next steps fails because the document asks for 2.6.1 but mastodon wants 2.6.5
no way to follow the document, other version errors coming up later, and result is a mess of versions. and errors because this or that is missing or incompatible. End of trying. Delete vm.
Did opened a thread about it in mastodon discourse. ✔️
