vscode 远程卡在获取锁上

Question

我正在使用 vscode 在服务器上进行远程开发。虽然我的本地 ssh 工作完美，并且 vscode 也能够连接，但我无法理解为什么它在获取锁方面遇到困难：

这个问题在vscode 的 github 页面上提供，但在没有解决方案的情况下被关闭。

我按照威胁中的建议尝试了设置remote.SSH.useFlocktofalse和remote.SSH.lockfilesInTmpto true，但没有解决问题。要么 vscode 陷入尝试连接 ssh 的循环，要么同样的问题仍然存在（与威胁中的相同）。

有谁知道问题可能出在哪里？提前致谢。

更新： 我按照下面答案中的建议尝试了群体测试。锁无法解开，永久卡住。因此，我认为flock确实是问题所在。flock如前所述，远离也没有解决问题。

Answer 1

您是否尝试过使用 shell 并手动运行集群？

这是一个简单的示例脚本，您可以使用它来测试集群是否正常工作。
