How do I update a GitHub forked repository to a specific branch/tag?

Question

I want to upgrade a forked repo which I forked 1 year ago to a specific tag. Anyone know how to do this ?

Answer 1

If you did not already do that:

• Clone the forked repository on your machine.
• Add an upstream remote to the original repository ( git remote add upstream <url> )

Then:

• git fetch upstream --tags
• git checkout -b <branchname> <tagname>

After that, you will have a new branch named branchname which is at the same state as the tag. Finally,

• git push origin <branchname>

pushes the new branch to your GitHub fork of the repository.

(I assume this is what you want; if you just want to have the tags in your fork, use git push origin --tags )

Answer 2

我按照以下步骤解决了我的问题：

• git checkout master
• git remote add upstream <origianl_repo_link>
• git fetch upstream
• git rebase --onto tags/<tag_name> upstream/master master
