Trying to access git-bash
prepared git repo with canonical git
, and I’m getting:
$ git pull
fatal: Unsupported SSL backend 'schannel'. Supported SSL backends:
gnutls
Following Using Git Bash under WSL, I’ve done git config http.sslBackend openssl
:
$ git config http.sslBackend
openssl
$ git config --global http.sslBackend
openssl
Following tip from reddit, I’ve done:
sudo apt install -y gnutls-bin
# and here are my installed packages:
ii gnutls-bin amd64 GNU TLS library - commandline utilities
ii libcurl3-gnutls:amd64 amd64 easy-to-use client-side URL transfer library (GnuTLS flavour)
ii libgnutls-dane0:amd64 amd64 GNU TLS library - DANE security support
ii libgnutls30:amd64 amd64 GNU TLS library - main runtime library
What else I’m missing?
$ lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description: Debian GNU/Linux 10 (buster)
Release: 10
Codename: buster
Run within Windows WSL.
PS. After all above tweaking, git-bash
can still pull
this git repo just fine, so I guess the SSL backend 'schannel'
is configured somewhere else in this repo.
PPS. Found that it has nothing to do with "git-bash
prepared git repo", as even cloning a fresh one will give me the exact same error.
Here is my git config --show-origin -l
output, let me know if I need to include more:
$ git config --show-origin -l | grep -E 'ssl|http'
file:/home/me/.gitconfig http.sslbackend=openssl
file:.git/config http.sslverify=false
file:.git/config http.sslbackend=openssl
file:.git/config http.emptyauth=true
file:.git/config remote.origin.url=http://xxx:8080/tfs/DefaultCollection/xxx
file:.git/config lfs.http://xxx:8080/tfs/DefaultCollection/xxx/info/lfs.access=ntlm

In general, the
http.sslBackend
option is only usable on Windows. Most Linux distros don’t offer it as an option, since they don’t compile with multiple TLS libraries.The proper solution is to remove all of the
http.sslBackend
options:If you must use OpenSSL for some reason, you’ll need to compile with it yourself. Most Linux distros are legally prohibited from distributing Git linked to OpenSSL under the GPLv2, so they typically don’t do that.
As the solution provided by @bk2204 didn’t work for me i tried to change it manually to "gnutls" value and it worked.
1- I tried @bk2204 fix but it didn’t work for me.
2- tried to set http.sslBackend to "openssl"
Nope
3- "If the cmd is proposing gnutls, why not use it?
4- Change it manually!
Tadá!
.gitconfig result
Workaround solution that resolved this issue is to remove all the configuratios from –global and –system.
Added required configuration one by one.
