I'm on my phone at this moment, but if I remember correctly we are moving to the maintained fork of paperclip with the next release.

What's the solution if I wanna stay on stable? Downgrade ruby to 2.7.2?

[jarednorman]

Yeah, for now 2.11 doesn't support Ruby 3.0.

Another solution could be switching to ActiveStorage.
If your application is already running on Rails >= 6.1, you can migrate any existing Paperclip uploads with a task like this (_could need some updates for Rails 6.1_) and change AppConfiguration#image_attachment_module and AppConfiguration#taxon_attachment_module settings.

An alternative but much more complex approach would be writing and registering your own image_attachment and taxon_attachment modules, with your custom attachment management implementation.
