AFAICT http2 support is currently intentionally dropped from curl because the dependency nghttp2-dev is not in the 'main' archive, but in the community supported 'universe' archive.
Quoting the curl package changelog: curl (7.52.1-4ubuntu1) zesty; urgency=low * Merge from Debian unstable. Remaining changes: - Drop dependencies not in main: + Build-Depends: Drop libssh2-1-dev, and libnghttp2-dev. + Drop libssh2-1-dev from binary package Depends. + debian/control: drop --with-nghttp2 -- Gianfranco Costamagna <locutusofb...@debian.org> Sun, 09 Apr 2017 13:07:51 +0200 https://launchpad.net/ubuntu/+source/curl/+changelog#detail_curl_7.52.1-4ubuntu1 So, to resolve this issue it would seem that Canonical first must be convinced to take on official support for the nghttp2 package. Not sure how we're supposed to do that? Cheering from the sideline has obviously not worked very well for this issue so far. :) -- 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
