If its over SSH, you can use the following:

For a higher debug level for type -vv or -vvv for debug level 2 and 3 respectively:

# Debug level 1
GIT_SSH_COMMAND="ssh -v" git clone 

# Debug level 2
GIT_SSH_COMMAND="ssh -vv" git clone 

# Debug level 3
GIT_SSH_COMMAND="ssh -vvv" git clone 

This is mainly useful to handle public and private key problems with the server. You can use this command for any git command, not only 'git clone'.
