others-how to solve git fatal: unable to access: SSL certificate problem: self signed certificate ?

Dec 12, 2020

Problem

When we git clone a repository from our private git server like gitlab or github enterprise , sometimes ,we get this error:

➜   git clone https://10.1.1.1/bswen/testrepo1.git        
Cloning into 'testrepo1'...
fatal: unable to access 'https://10.1.1.1/bswen/testrepo1.git/': SSL certificate problem: self signed certificate

Environment

MacOS git version 2.21.1 (Apple Git-122.3)

Reason

Our git server use a self-signed private ssl certificate, so that’s the problem, git client can not verify this certificate.

Solution

We should disable the git client’s SSL certificate verification as follows:

git config --local http.sslVerify false

Or , if you want to set this configuration globally ,you can set as follows:

git config --global http.sslVerify false

You can verify the settings as follows:

git config --list --local

One more thing

Thanks to this answer about git configurations in stackoverflow:

To understand Git configuration, you should know that:

Git configuration can be stored at three different levels. Each level overrides values at the previous level.

1. System level (applied to every user on the system and all their repositories)

to view, git config --list --system (may need sudo)
to set, git config --system color.ui true
to edit system config file, git config --edit --system

2. Global level (values specific personally to you, the user).

to view, git config --list --global
to set, git config --global user.name xyz
to edit global config file, git config --edit --global

3. Repository level (specific to that single repository)

to view, git config --list --local
to set, git config --local core.ignorecase true (--local optional)
to edit repository config file, git config --edit --local (--local optional)

It works!
