Error: object not found when git pull origin refs/tags/mytag

[miltalex]

Hi,

I get the Error: object not found when I try to git pull from a tag:

err = w.Pull(&git.PullOptions{
		RemoteName:    "origin",
		ReferenceName: plumbing.ReferenceName("/refs/tags/mytag"),
	})

Any help appreciated.

Are you using a shallow clone? If so shallow clones are broken (#1143). Even without shallow cloning, this can still happen on occasion. This appears related to #1151. Here's my error handling:

// plumbing.ErrObjectNotFound is a work around for https://github.com/src-d/go-git/issues/1151
if err != nil && err != git.NoErrAlreadyUpToDate && err != plumbing.ErrObjectNotFound {
  return err
}

I hope this helps.
