Ignoring Self-Signed SSL Certificate Errors while using Git

How to get Git to play along with self-managed Git servers

When I interact with most code repositories they’re often hosted on Github, or Gitlab, or some other managed Git service. By and large HTTPS support is a foregone conclusion; I never have issues using git commands or GUI clients to interact with those repositories.

Sometimes, though, I find myself working with a repository located in an internal instance of Github Enterprise. When self-managed servers like these have HTTPS support added to them it’s via a self-signed certificate. In these cases I often run up against errors like this after trying to clone a repository or fetch the latest remote changes:

fatal: unable to access ‘': SSL certificate problem: unable to get local issuer certificate

When this happens, I do one of two things:

If I’m initially cloning the repo down to my machine then I add -c http.sslVerify=false to my git command:

git -c http.sslVerify=false clone

Afterwards I open up a cloned repository’s .git/config file and add the following setting:

  sslVerify = true

This eliminates the need for me to add the http.sslVerify flag to subsequent Git commands. Additionally, interactions with the repository via GUI client will also ignore self-signed certificate errors and function as expected.
