I\'m getting a strange \"cannot lock ref\" error when trying to pull changes from github. I\'ve tried git gc, and looked around for similar errors but can\'t find a solution.>
error: cannot lock ref 'refs/tags/v2.8': 'refs/tags' exists; cannot create 'refs/tags/v2.8' From github.com:k3it/qsorder
Try deleting your local tag v2.8 and v2.9 then pull again.
$ git tag -d v2.8
$ git tag -d v2.9
$ git pull
If you want to delete all local tags by a command:
$ git tag | xargs git tag -d
