Two users SSH remove Ubuntu, one will fail

[jllixiao]

Type: Bug

I have 2 users A and B use SSH remote to Ubuntu to do development work.
If A's vscode works fine, then B's will not work. By not working, the code intellisense, project loading all failed.

Reinstall DevKit is not helping. But if B removes /tmp/csdevkit folder, then restart vscode, B's vscode will work well. But A will fail.

Steps to Reproduce

A starts vscode, then B starts.

Expected Behavior

Both A and B can work well.

Actual Behavior

B will fail.

Starting with @dibarbet for the call stack with CA in specific.

But the insight around reuse of /tmp/csdevkit could be something for us to chase down. @AArnott would you know what other teams are involved with that?

[dibarbet]

@jonathanjyi this looks similar to #1354 but perhaps with a different cause. Would you mind taking a look?

[jonathanjyi]

Hi @jllixiao thanks for reporting this issue and pasting the Log. I'll take a look to see what's going on. In the mean time, could you elaborate a bit more on the setup?

1. Are the Windows users using the same SSH credentials to login to the Ubuntu box?
2. Since you mentioned SSH, I assume that the users are starting VS Code on the Windows side, and using a remote connection login to connect through SSH to the Linux side?
3. Can both Windows users start C# Dev Kit Extension on their Windows machines without logging in to the remote Ubuntu box successfully with no crashes or errors?
4. Are both users opening the same project?

Adding @webreidi as owner to comment on scenario support after we understand scope of break.

Hi @jonathanjyi ,

1. No, we use different credentials to ssh to the Ubuntu server.
2. Yes, we both use VSCode on Windows to remote to the Ubuntu server. One is Windows 10 Enterprise, the other is Windows 11 pro.
3. Yes, it works well on our own Windows system.
4. No, we open different project.

Hope this helps,

Thanks a lot,

@jonathanjyi, the 'needs-more-info' label has been removed upon receiving further response from the original bug filer.

[jonathanjyi]

@jllixiao, apologies on the delay. I was able to repro this issue locally and know what the issue is.

Using your example of Users A and B, what is happening here is that User A is the first open and start the C# Dev Kit extension. That means User A also creates the /tmp/csdevkit folder with their permissions, thus preventing User B from writing to that directory.
Example: drwxrwxr-x User_A User_A csdevkit

I'm investigating a solution internally and will update here.

[jonathanjyi]

Also, @jllixiao I wanted to add that to unblock your users until we get a fix out, you can set the /tmp/csdevkit folder to world write (777) at the folder level.

sudo chmod 777 /tmp/csdevkit should do it. Let me know if this doesn't work for you.
