Git 将现有仓库推送到新远程：远程主机关闭与 github.com 的连接

Question

我有一个想要推送到新网址的现有仓库。我尝试了以下方法。

$ git remote set-url origin git@github.com:user/new-repo.git
$ git config --global http.postBuffer 1048576000
$ git config --global ssh.postBuffer 1048576000
$ git push --verbose

To github.com:user/new-repo.git
! [remote rejected] master -> master (failed)

在单独的 repo 副本中：

$ git remote set-url origin https://github.com/user/new-repo.git
$ git remote -v
origin  https://github.com/user/new-repo.git (fetch)
origin  https://github.com/user/new-repo.git (push)

$ git push

error: RPC failed; curl 18 transfer closed with outstanding read data remaining

Everything up-to-date

原始 repo 托管在 gitlab 上。使用 github 的导入功能也会失败，没有描述性消息。 Gitlab 显示 repo 为 3.7GB，并且没有非常大的单个文件。

任何调试想法？谢谢。

Answer 1

检查问题是否仍然存在：

• 使用最新的 Git 2.28
• 使用 https URL（用于测试）：git remote set-url origin https://github.com/user/new-repo.git
• 使用新存储库中的小内容（同样，用于测试：第一次提交时只有几个小文件）

最后一点似乎很中肯：

remote: fatal: pack exceeds maximum allowed size

尝试并确保您的第一次提交不会“太大”，以至于 GitHub 推送无法处理。
