How To Delete Tags On Remote Repos
what i learned
you can delete remote tags from your github repository using git push --delete origin <TAG NAME>
or you can delete locally and then push those changes to your remote repo
how i learned
recently someone became the very first contributor to pypums
and when i merged their contribution and tried to automatically build and publish the package to PyPI i found myself making an error. at first i tried to create a release on github then i realized i had not changed the versions accordingly in setup.py and the other files. i had already tagged it as 0.0.7, however, so i had to delete the tag, fix the versions, tag it again.
i had done this before a few times but this time i found this very quick and easy explanatory post: how to delete local and remote tags on git
