I typically use vscode-remote to use vscode on a linux server over ssh. When I got the July 2024 release today, I started getting errors connecting to the server.

Looking at the output (included below) it seems like there were errors during server installation that resulted in crashes on startup due to missing javascript modules.

Workaround was to rm -rf ~/.vscode-server from my ssh server.

A handful of my colleagues also experienced similar issues. We seem to have these kinds of issues every time a new update gets released.

Expected Behavior

When updates roll out, it doesn't result in javascript errors that crash the app.

Steps To Reproduce

Wait for an automated upgrade to be rolled out

Remote-SSH Log

logs here (too big to attach) https://gist.github.com/Hnasar/4b295e51f2fc255ccbfc1dee3d4f9248

Anything else?

The home directory on the linux server is mounted with NFS, if that matters.

The text was updated successfully, but these errors were encountered:

Facing the same issue since today morning. Downgrading to 1.91

Terrible instability for me in the last 2 weeks for remote tunnels.

Hnasar · 2024-09-05T19:39:45Z

Once again, after another update, 1.93 and we're seeing reports of failed connections. One user reported deleting ~/.vscode-server on the remote machine fixed vscode being unable to connect over ssh.

(e.g. here's another bug filed #10229 )

One error I saw today in the macOS logs on the local side:

@bamurtaugh I'm wondering if you're the right person to help with this severe issue. Every time there's a vscode upgrade, it breaks for the remote-ssh extension for a percentage of our team members. This is extremely disruptive.

I support our team's usage of vscode and our workflow relies on using remote linux servers for development. Team members report inability to connect, missing extensions, crashes, etc, and this requires they manually rm -rf ~/.vscode-server.

For example, today after one team member was unable to reconnect using remote-ssh after the upgrade rolled out, we were able to see these logs on their local macbook:

Using vscode reminds me of when I used to flash ROMs on my phone because I got pretty good at reinstalling all of the apps.

This issue has been plaguing us for months and is driving users to use pycharm. I'm wondering if we should firewall off the vscode upgrade domain due to this issue. I'm happy to schedule a debugging call or provide any other information needed. Thank you for your work — otherwise, I'm a big fan of this extension!

bamurtaugh · 2024-09-13T16:47:33Z

Thanks for looping me in, and sorry to hear about the trouble. Looping in @joshspicer for his insights too!

joshspicer · 2024-09-13T17:40:43Z

Thanks for the logs @Hnasar. Specifically for what you've shared above, does this connection issue reproduce on the previous release version (0.113.1)?

I see /mnt/nfs_fs_1/... in that stack trace. Is the remote machine mounting in the user's home folder from elsewhere? Could you please share a bit more about the configuration of the remote system?

The nfs is raising flags for me. One thing we can try is setting the serverInstallPath to a path on the remote that isn't mounted in from elsewhere:

We also have this setting that was introduced specifically for (seemingly) this kind of setup:

If you decide to give this a go, please use the latest pre-release build of the extension. Changing channels can be done easily in the extension UI:

joshspicer · 2024-09-13T17:42:29Z

As an aside

We're investing this iteration (and likely the next one or two after) on improvements on how we define a baseline reliability metric for this extension (to prevent these unnecessary regressions). Some details are published publicly on our iteration plan and other ideas are under discussion. Please let me know if you have any other feedback you think would be valuable for me to incorporate.
