Description

In my network environment, it is very unstable to migrate github repo with https protocol(git clone https://github.com/ownxxx/repoxxx.git), so I have to use ssh protocol(git clone [email protected]:ownxxx/repoxxx.git) to migrate github repo.
when i use the migrate feature of gitea to mirror github repo, and type the ssh url([email protected]:ownxxx/repoxxx.git), it will show the invalid URL message: "is not a valid URL."
does gitea really support migrate github repo with ssh protocol now? or it's my migrate method is wrong?

BTW: i have make and setup the pair of RSA ssh key for github, and can clone the repo successfully with raw command method on the terminal.

thanks a lot!
