Question

Is it possible to untag a revision that has been push upstream using git.

This is what has happened:

git tag 1.1
git push --tags origin master

Doh! That was meant to be version 1.1beta

Can you rebase and repush upstream. No other member of my team has pulled from origin yet.

Answer 1

You can delete a remote tag the same way that you delete a remote branch.

git push origin :1.1

And delete your local tag with:

git tag -d 1.1
