How to "reinitialize" git after changing ssh key?

Question

git

Hi
I changed my ssh key.
In an old bitbucket project, git pull stopped working:

Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
fatal: Could not read from remote repository.

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

git clone works. The key is registered.
What should be done?

Answer 1

eval `ssh-agent -s`
ssh-add /path/to/key/file
git pull
