@aimorris Not sure I can help. I am not really good analyzing logs but I could see this
ssh_askpass: exec(/usr/bin/ssh-askpass): No such file or directory
Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists
Are you trying to start MM remotely? Does MM require root (sudo)? If you start it remotely, have you tried to start it locally?
