gitlib configures ssh keys and then pulls the report Could not read from remote repository in Sourcetree
Solution: delete the current key, then regenerate the key,
ssh-keygen -t rsa -C '***********@xxxx.com'
A folder will be generated locally in C:\Users\your username.ssh, which contains two files, id_rsa and id_rsa.pub,
and then copy the contents of the id_rsa.pub file to https://github.com/settings/keys create a new one,
