Ionic Migration "git push ionic master"

Hi !

I already have an app and I migrated to Ionic Pro.

The problem is that I want to push to dashboard.

I did : git push ionic master

and it ask me the passphrase key and I fill it

and it returns me :
error: update_ref failed for ref ‘refs/remotes/ionic/master’: cannot update the ref ‘refs/remotes/ionic/master’: unable to create directory for ‘.git/logs/refs/remotes/ionic/master’: Permission denied

I really don’t know what to do.
