Question

Body

In a private repository, I viewed a pull request at a certain commit. A co-worker force-pushed the whole branch.

I still have the link to the commit on github, it says:

This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.

I want to check out that commit, but I don't know how to access it.

I am not interested in a solution from the co-workers local clone to checkout the commit. I also do not have this commit locally.

• I only have access to github
• I see the commit in the URL https://github.com/user/repo/commit/hash
• how to check out this specific commit

?

I tried git checkout origin/hash or similar ideas, but that does not work.
