git - 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 private, which broke the fork. He then changed settings which would allow forking private repositories. me/A.git is still not a fork but a simple clone. How can I make me/A.git a fork again, without having to:

1. Fork org/A.git again which would result in me/A-1.git.
2. Delete me/A.git.
3. Rename me/A-1.git to me/A.git.
4. Push local changes to the new me/A.git.

I want to avoid the above 4 steps because I have additional contributors as well as branches in the original me/A.git and taking care of all that is just cumbersome for something which seems to be so simple.

Answer 1

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.
