解决方案:

push failed for branch (n/a (unpacker error))

This is a bug in JGit (issue 408). TLDR: Newer git clients are optimized to send less data on the wire. JGit expects complete data to be sent, but there are scenarios where native git can optimize-out sending objects. By default, JGit requires everything sent be complete and referenceable.

If you experience this, the workaround is to temporarily disable the reachable check for the receive pack, push, and then re-enable the setting.

git.checkReferencedObjectsAreReachable = false

在GitBlit的服务端配置中添加上面的代码，就可以确保push成功。等到push成功之后，再删除这段配置。
