How can i upgrade the Apache version 2.4.6 to a newer version so it can support HTTP/2 ?
Beginning in Apache 2.4.17, there is an experimental module that supports http/2:
There unfortunately aren't any packages that we can officially support or recommend. You'd likely need to look into a third party repository for that, which means it's not something we've done any testing with. That's normally something we'd recommend against.
However, if you have a test server, and you really want http/2, you could always try out packages from a third party repository on your test server.
