How to unpack packed-refs?

Question

I cloned a project from github with git clone --mirror. That left me with a repository with a packed-refs file, a .pack and an .idx file.

Answer 1

There is a workaround that worked for me and might work for some of you:

Basically, Delete all the tags locally (removes it from packed-refs) and then fetch it again.

git tag | xargs git tag -d && git fetch --tags
