"ExtensionHostConnection#buildUserEnvironment resolving shell environment failed Error: Unable to resolve your shell environment in a reasonable time. Please review your shell configuration." in linux remote ssh #6109

Closed SamKiley closed 2 years ago

SamKiley commented 2 years ago

Issue Type: Bug

On windows 10, using vscode remote ssh to connect to ubuntu 16.04 linux machine. I have issues with connecting to this ssh remote on the first attempt. In the log file in .vscode-server, the error "ExtensionHostConnection#buildUserEnvironment resolving shell environment failed Error: Unable to resolve your shell environment in a reasonable time. Please review your shell configuration." is encountered many times, until it eventually stops getting the error. I often have to attempt to reconnect 5 or so times before it stays connected and doesn't give an error prompt. It eventually works, but it really annoying and sometimes "connects" but there is an issue with the extension host and the search or my extensions doesn't work at all

Is there anything overly time consuming in your ubuntu's shell setup/configuration?

Could I also see your Remote-SSH logs from the Output tab on a failed connection?

tanhakabir commented 2 years ago

You could look here for tips: https://code.visualstudio.com/Docs/supporting/FAQ#_resolving-shell-environment-fails

SamKiley commented 2 years ago

I have looked at that guide before and it doesn't really mention anything other than the time consuming .bashrc stuff. I timed the .bashrc execution and it takes around 0.4 seconds, so definitely not the 10 seconds that it says would be an issue. There are other issues somewhere I believe where people get this error and don't have slow .bashrc, but those issues are never resolved.

Also, my issue is potentially similar to https://github.com/microsoft/vscode-remote-release/issues/6107 that I think you are also working on. (minus the thing from waltoncade, I think they just need to delete .vscode-server and rerun)

Remote-ssh logs where I get a "Could not fetch remote environment" and "Failed to connect to remote extension host server :Error: Time limit reached" pop ups.

Even more confusing, when I just tried to open vscode to provide those logs, the .vscode-server log file did not have that original error about not resolving the shell. After it failed and provided the errors above I simple closed vscode and tried again. Like typical, it opened fine then. Below is the .vscode-server log for the failure and the successful connection: (Usually this is where the resolving failure error shows up)

Sorry about the delayed response. @Tyriar I'm not sure how we resolve shells in remote windows. Do you have an idea why there'd be a discrepancy between opening a shell in vscode in a remote window and the actual time it takes to resolve .bashrc?

SamKiley commented 2 years ago

Also I did have a "bash" in my .profile.local. I removed it, but that did not end up helping at all. And to reiterate, I am using windows 10 vscode and remote ssh into a linux machine with a .vscode server. Your statement of "resolve shells in remote windows" confused me. Sometimes when I try to open the remote ssh it fails, but does not give the resolving shell error, others times it does.

tanhakabir commented 2 years ago

"remote windows" I mean remote vscode windows. Not Windows as in the OS.

I'm sorry I don't know what could be the issue here but @Tyriar or @meganrogge might know?

meganrogge commented 2 years ago

when VS Code launches, we source a "dev environment" by running your default shell. When this fails we show the error message that your shell returned. Thus, you have some issue in your shell init files that's causing that error. You need to investigate on your end as it's a problem with your environment, not with VS Code.

We do this before showing that error:

https://github.com/microsoft/vscode/blob/87b365f433427f0b936b02382b177abebc7c6369/src/vs/platform/environment/node/shellEnv.ts#L126-L151

Tyriar commented 2 years ago

The remote case is a little different, but it still does essentially the same thing:

https://github.com/microsoft/vscode/blob/ef8700e85e8bacf471a60a44fcd72a0781258569/src/vs/server/node/extensionHostConnection.ts#L28-L35

That error displays when your shell takes over 10 seconds to start up:

https://github.com/microsoft/vscode/blob/1ab07c536abfb7ac05e57728ab1fb1e1d40190e8/src/vs/platform/environment/node/shellEnv.ts#L75-L79

I agree the issue is with your environment.
