After manual installation of Cython there is another error

So I had to manually install libssh2-devel and openssl-devel to make it working.

I believe all of this happens because there are no pre-built binaries for Amazon Linux.
So I'm wondering where it's possible to add distributions with pre-built binaries.

Even after successful installation it still doesn't work

@kdart-brt would you be able to take this on and release a new version? Unfortunately, ssh2-python has become stale and we're looking at this fork as a replacement.

The same error at Fedora 39 server

Hi @ZlobinDA I decided to publish a (hopefully) temporary package that works with python 3.12 (linux and mac) if you're interested in using it instead.
