Can't push all tags

When I try to push all tags, I get this exception:

LibGit2Sharp.LibGit2SharpException: not a valid reference 'refs/tags/*'
   at LibGit2Sharp.Core.Ensure.HandleError(Int32 result)
   at LibGit2Sharp.Core.Proxy.git_remote_push(RemoteHandle remote, IEnumerable`1 refSpecs, GitPushOptions opts)
   at LibGit2Sharp.Network.Push(Remote remote, IEnumerable`1 pushRefSpecs, PushOptions pushOptions)
   at CallSite.Target(Closure , CallSite , Object , Object , Object , Object )

Here's my PowerShell code:

$pushOptions = New-Object -TypeName 'LibGit2Sharp.PushOptions'
$repo = New-Object 'LibGit2Sharp.Repository' ($RepoRoot)
$remote = $repo.Network.Remotes | Where-Object { $_.Name -eq 'origin' }
$repo.Network.Push($remote, 'refs/tags/*', $pushOptions)

I've also tried using refs/tags/*:refs/tags/* as the refspec, but that fails too. I can push individual tags with refspec refs/tags/tag_name.

從 PowerShell 範例和 Repository.Network.Push 進入點開始，比較個別標籤的 refspec 與 issue 中顯示的萬用字元形式。使用 PushOptions 和 refs/tags/* 重現例外，然後追蹤 refspec 的處理方式。當推送所有標籤時不再出現無效參照錯誤並成功完成，即表示完成。
