git gnutls_handshake() failed: Error in the push function

[Peter Parzer]

When using git with https:// behind a corporate proxy it fails often with the error message:

gnutls_handshake() failed: Error in the push function.

For example:

git clone -q --mirror https://github.com/JuliaDiff/DualNumbers.jl.git /home/user/.julia/v0.4/.cache/DualNumbers
fatal: unable to access 'https://github.com/JuliaDiff/DualNumbers.jl.git/': gnutls_handshake() failed: Error in the push function.

After repeating the same command several times it finally works. Sometimes git work even the first time, but this is seldom. Usually it works when I repeat the command 2 or three times.

System: Ubuntu 16.04.2 LTS amd64, kernel 4.4.0-78-generic
git: 1:2.7.4-0ubuntu1.1
curl: 7.47.0-1ubuntu2.2
libcurl3-gnutls: 7.47.0-1ubuntu2.2

Status changed to 'Confirmed' because the bug affects multiple users.

Using git is already the newest version (1:2.7.4-0ubuntu1.3) on arm64, git worked on the 3rd attempt, with 1st and 2nd giving the 'push' error.

we are affected as well.

this is behind a perfectly fine working corporate proxy (and yes in the env http_proxy / https_proxy also uppercase are set)

is there any way to get this solved .. this is (as we sit on docker and build the images automatically a big bummer for us)

[Kenyon Ralph (kralph)]

What fixed it for me was explicitly setting git's http.proxyAuthMethod to basic: git config --global http.proxyAuthMethod basic

If you run your git commands with environment variable GIT_CURL_VERBOSE=1, you might see that the proxy authentication is failing.

This happened for me when I had https_proxy etc set with a https protocol (e.g. set to https://localhost:3128) instead of just http.

Facing same issue after following above comments solution:

unable to access 'https://bitbucket.org/xyz_orgname/productlfs.git/': gnutls_handshake() failed: Error in the push function.

Any other solution exists? Thanks in advance.
