Debian/Ubuntu packages doesn't have 10/11

At the moment there aren’t packages up for llvm 10/11 despite saying there are. There also aren’t releases for these version at There are releases for version 10 up on the github.

Is this intentional?

Depends on the version of the distro (Ubuntu xenial should have it for example). supports the last three versions of llvm (currently: 12, 13 & 14).

I leave 10 or 11 for the distro supported when they were published.

I hope it is clear!
