git clone always fails with "Failed sending HTTP request"

On one particular host, I cannot git clone any GitHub repo over https:

git clone https://github.com/llvm/llvm-project.git
Cloning into 'llvm-project'...
fatal: unable to access 'https://github.com/llvm/llvm-project.git/': Failed sending HTTP request

Everything similar I've found talks about SSL server cert verification failing (e.,g. here or here). Running the command under strace does indicate the command rifling through all my certs before failing, but the http.sslVerify => false hack has no effect (just like the second question above).

I've reinstalled the git & ca-certificates packages; no effect.

Anyone have any thoughts? Even suggestions as to how to induce git to tell me more about what's going wrong would be appreciated.

github ssl-certificate git

Had the same problem with another solution. I post this answer since this problem smh appeared on all my MX Linux boxes at the same time. In my case it was a mismatched version that could be resolved with the solution from here.

# apt reinstall libcurl3-gnutls/stable did the trick.

It's recommended to have the debian/security apt repos active for this.

If you git version is recent enough, you can use trace2 to display what Git is trying to do:

GIT_TRACE2=1 git clone https://...
GIT_TRACE2_EVENT=1 git clone https://...

I suspect a different (older) libcurl on your host, compared to other ones, which would result in HTTP request being not sent.

You can also, in /usr/bin, check the dynamic library dependencies of git:

ldd git
VonC_63090

Same problem here on Debian Buster!

The problem is reported here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=987187

My computer was like that:

DEBIAN10$ apt policy curl:amd64 libcurl4:amd64 libcurl3-gnutls:amd64

Then, I did the trick!

DEBIAN10$ apt reinstall libcurl3-gnutls/stable

And it is ok now! (thanks @Cobalt)

My config after the change:

Besides, add the content bellow to the /etc/apt/preferences.d/99debian-backports file, in order to avoid returning to the problem in the next upgrade!

/etc/apt/preferences.d/99debian-backports

Pin: release a=buster-backports

Package: libcurl3-gnutls:amd64

For some unknown reason the solution before is not working anymore.
Now, it seams to be fine.

sudo apt-get -t buster reinstall libcurl3-gnutls:amd64=7.64.0-4+deb10u2
sudo apt-mark hold libcurl3-gnutls
