Github convert existing repo to a fork

Question

My organisation has a main repo called org/A.git. I forked it as me/A.git to Github first. My organisation admin made org/A.git privat

Answer 1

I don't think you can. But the four steps you describe probably take less time than the time it took to post here. :-)

For step 4, how about git push --all origin?

Answer 2

This is very, very, very old... However, I recently faced a similar circumstance myself, and contacted GitHub Support. For me, it wasn't that it was a fork originally and then it was broken, but rather I created my own repo manually before understanding what a fork was (still new to Git). GitHub Support confirmed there was no way to do it, unfortunately.

The quote from them:

Thanks for reaching out! Sorry for the trouble, but it isn't possible to attach a repository as a fork of another in this kind of situation -- repositories can't move from one fork network to another, or to a network they were not originally created from.
