[Remote-SSH Bug]: After update, Remote save file silently fails

[drscotthawley]

Is there an existing issue for this bug?

• I have searched the existing issues

Required Troubleshooting Steps

• I have followed these troubleshooting steps
• I have tried both values of the remote.SSH.useLocalServer setting

Connect Locally

It connects successfully

->

Pressed the button to update VSCode tonight and now remote saving no longer works.

Can read files on remote server but saves never get made. No error message, just silently fails to update the remote file.

Expected Behavior

Pressing Save (Cmd-S) would save the file to the remote server, as has worked fine for a long time, up until applying tonight's VSCode update.

Steps To Reproduce

1. From Mac laptop, use VSCode Remote to connect to remote Ubuntu server
2. Open .py file
3. Make changes to file
4. Press save (Cmd S)
5. Run your code and notice that the changes haven't occured
6. Cat the file in the unix shell, notice that it's still the old version of the file
7. Double check to make sure you have the directories correct
8. Try quitting and restarting VSCode to no effect.
9. Kill the remote server and start anew, no effect.

Anything else?

I will gladly downgrade to previous VSCode if it'll let me somehow.

[drscotthawley]

Update:
Just noticed that LOCAL execution of new VSCode also fails to save changes to files.
This suggests that the problem is not (necessarily) Remote-SSH related.

Downgrading Mac VSCode to March 2024 (version 1.88) did not resolve this issue. Will look for some Settings issue. (note: file/directory write persmission is not the issue.)

Update 2:
Wait, Cmd-S doesn't work, but File > Save does. (??)

[drscotthawley]

Wow, completely deleting VSCode and all user-related settings directories, preferences, and all Extensions --- everything -- and reinstalling from scratch: still no local saves possible.

[drscotthawley]

Okay, reverting to Feb 2024 version of VSCode fixed everything. Remote saves and local saves both work again.

I'll ignore the "Update VSCode" button even more diligently now. ;-)

Closing.

[drscotthawley]

Nope, remote files are not saving again. :-/

trying to close the vscode setting-> remove-ssh:Use Exec Server can solve this problem. I did so.
