尝试更新glibc

参考Visual Studio Code Remote Development Frequently Asked Questions，将glibc更新至2.28（更多细节请参考Linux Prerequisites for Visual Studio Code Remote Development），但重启后问题仍未解决。
尝试删除服务器上的.vscode-server，重新连接VSCode仍然无效。同时，删除客户端.ssh/known_hosts中的相关条目也未产生效果。

问题定位——VSCode1.86不兼容特定旧版本Linux

最终，在搜索关键字"Waiting for server log…“时找到了问题的根本原因，即VSCode 1.86版本不再支持CentOS7（包括Ubuntu18.04等），因此需要手动回退至1.85版本。
首先，使用Ctrl+Shift+P打开用户设置，搜索"update”，将应用程序的更新模式设置为"none"，然后重新启动VSCode。
安装1.85版本的VSCode后，发现SSH Remote选项消失。在搜索插件时，发现先前版本的Remote - SSH插件与1.85版本不兼容。为解决此问题，卸载了Remote - SSH插件，并重新安装。此时，成功连接到远程开发环境。

随后，安装了1.85版本的VSCode，但发现SSH Remote选项不再可见。

在查找插件时，发现先前版本的Remote - SSH插件与1.85版本存在不兼容性。

为了解决这个问题，我卸载了Remote - SSH插件，并进行了重新安装。经过这一步骤后，成功连接到远程开发环境。
