git@github.com：来自公共存储库的权限被拒绝（公钥）

Question

I can not clone repositories from github even if there are public:

git clone https://github.com/github/fetch.git
Cloning into 'fetch'...
git@github.com: Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

Everything works if I want to clone from eg bitbucket.

You wrote clone command with https:// URL but Git started to clone with git@ scp-like SSH URL. This means you have url.….insteadOf section(s) in your Git configs that overwrite your URLs on the fly.

Run

git config --list --show-origin | grep -Fi insteadof

to find out where exactly is the problematic configuration and comment out or remove what you do not need now.

Most probably you have a section like this in your global ~/.gitconfig :

[url "git@github.com:"]
    insteadOf = https://github.com/

To remove it:

git config --global --remove-section url.git@github.com:

Or use your editor to inspect and edit the file:

git config --global --edit
