远程 SSH：“/bin/bash：没有这样的文件或目录”当尝试连接到远程服务器时
| 软件 | 版本 |
|---|---|
| 客户端计算机操作系统 | Windows 10 x64 |
| 目标计算机操作系统 | Ubuntu 20.04.4 LTS (GNU/Linux 5.4.0-100-generic x86_64) |
| VS Code | 1.65.0 |
| VS Code Remote - SSH（稳定） | 0.76.1 |
我正在尝试使用 VS Code 中的远程 SSH 扩展来编辑远程服务器上的文件。在 C:\Users\me\.ssh\config 中，我配置了以下主机：
Host druid
HostName mydomain.com
Port 22
User myuser
IdentityFile "K:\PathToKey\id_ed25519"
当尝试连接到此目标主机时，系统会提示我输入其操作系统类型，有时还会提示输入密钥的密码，然后它失败了。我得到以下输出：

我相信这些行特别指出了问题的根源：

看起来插件的代码或脚本正在尝试运行 /bin/bash （在客户端计算机上？），但它使用的是 cmd .exe 未能成功执行此操作。我已经尝试了所有能找到的解决方法，但到目前为止没有一个有效。作为参考，我尝试过：
- 在
中的true和false之间切换remote.SSH.useLocalServerC:\Users\me\AppData\Roaming\Code\User\settings.json - 将
"PATH"值指向C:\Program Files\Git\和我的 VS Codeterminal.integrated.shell 中的 usr\bin、C:\Program Files\Git\bin或根本不存在 ("") .windowssettings.json中的terminal.integrated.shell.linux设置，希望它能够拾取bash.exe，或者至少覆盖其他地方设置不正确 - 将默认终端配置文件设置为 Git Bash 或 Ubuntu (WSL)
- 在 Remote.SSH 设置中指定 ssh 可执行文件和配置文件的绝对路径
- 运行
ssh -T -D 65124 druid bash中用于与远程 SSH 输出进行比较的 PowerShell 终端（给出一行：/bin/bash: No such file or directory） - 在两台目标计算机上运行
ldd /bin/bash并在 Ubuntu WSL 终端中比较输出（相同） - 检查主目录中的
.vscode-server目录以删除并重新生成，如建议的此处 - 运行
Remote-SSH ：在客户端计算机上的 VS Code 命令面板中杀死主机上的 VS Code 服务器...，这可能会或可能不会与上面的解决方案执行相同的操作 - 卸载并重新安装远程 SSH VS Code 扩展
我希望我会在写下这一切并回顾我的脚步的过程中弄清楚这一点，但我仍然不知所措。任何建议将不胜感激！

I'm trying to use the Remote SSH extension in VS Code to edit files on a remote server. In C:\Users\me\.ssh\config I have the following host configured:
Host druid
HostName mydomain.com
Port 22
User myuser
IdentityFile "K:\PathToKey\id_ed25519"
When trying to connect to this target host, I'm prompted for its OS type, then sometimes the key's password, then it fails. I get the following output:

I believe these lines in particular point to the root of the problem:
[21:35:07.714] Running script with connection command: ssh -T -D 65124 druid bash
[21:35:07.718] Terminal shell path: C:\Windows\System32\cmd.exe

[21:35:07.956] Got some output, clearing connection timeout

[21:35:10.542] Received install output: ]0;C:\Windows\System32\cmd.exe/bin/bash: No such file or directory
It looks like the code or script of the plugin is trying to run /bin/bash (on the client machine?), but it's using cmd.exe to do so unsuccessfully. I've tried every workaround I could find, but none have worked so far. For reference, I've tried:
- Switching
remote.SSH.useLocalServerbetweentrueandfalseinC:\Users\me\AppData\Roaming\Code\User\settings.json - Pointing a
"PATH"value toC:\Program Files\Git\usr\bin,C:\Program Files\Git\bin, or nothing at all ("") in theterminal.integrated.shell.windowsandterminal.integrated.shell.linuxsettings in my VS Codesettings.json, hoping it would pick upbash.exe, or at least override something incorrectly set elsewhere - Setting the default terminal profile to either Git Bash or Ubuntu (WSL)
- Specifying an absolute path to both the ssh executable and the config file in Remote.SSH settings
- Running
ssh -T -D 65124 druid bashin a PowerShell terminal to compare with Remote SSH output (gives one line:/bin/bash: No such file or directory) - Running
ldd /bin/bashon both the target machine and in an Ubuntu WSL terminal to compare output (identical) - Checking home directories for a
.vscode-serverdirectory to delete and regenerate, as suggested here - Running
Remote-SSH: Kill VS Code Server on Host...in the VS Code Command Palette on client machine, which may or may not do the same thing as the solution above - Uninstalling and reinstalling the Remote SSH VS Code extension
I was hoping that I'd figure it out in the process of writing this all down and retracing my steps, but I'm still at a loss. Any advice would be much appreciated!
