Public bug reported: libcurl supports HTTP/2.0 through libnghttp2, but the package on Ubuntu is not compiled with it.
Alternatively, a libcurl4-(gnutls|openssl)-nghttp2 might be a good idea. See also: https://curl.haxx.se/docs/http2.html curl CLI tool should not need an update, as it already has the commandline switches, but when you use them it comes back with unsupported protocol. drwilco@eris:~$ curl --http2 www.google.com curl: (1) Unsupported protocol drwilco@eris:~$ lsb_release -rd Description: Ubuntu Xenial Xerus (development branch) Release: 16.04 root@eris:~# apt-cache policy libcurl3 libcurl3: Installed: 7.47.0-1ubuntu2 Candidate: 7.47.0-1ubuntu2 Version table: *** 7.47.0-1ubuntu2 500 500 http://us.archive.ubuntu.com/ubuntu xenial/main amd64 Packages 100 /var/lib/dpkg/status ** Affects: curl (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1567697 Title: libcurl is missing http2 support To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/curl/+bug/1567697/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
