How do you remove a git tag that has already been pushed? Delete all git remote (origin) tags and Delete all git local tags.
git tag -d $(git tag -l)
git fetch
git push origin --delete $(git tag -l) # Pushing once should be faster than multiple times
git tag -d $(git tag -l)
For windows using command prompt:
Deleting local tags:
for /f "tokens=* delims=" %a in ('git tag -l') do git tag -d %a
Deleting remote tags:
for /f "tokens=* delims=" %a in ('git tag -l') do git push --delete origin %a
