ERROR: Unpacking failed: Files expected: 2399, is 2400

[niklaskorz]

Every time VS Code Server updates, it fails with the following error:

Updating VS Code Server to version ee2b180d582a7f601fa6ecfdad8d9fd269ab1884
Removing previous installation...
Installing VS Code Server for x64 (ee2b180d582a7f601fa6ecfdad8d9fd269ab1884)
Downloading: 100%
Unpacking: 100%
ERROR: Unpacking failed: Files expected: 2399, is 2400

The only explanation I can think of is that the auto-fix-vscode-server service runs too fast, i.e. between the unpacking and the checking of the unpacked files. Stopping the service before updating and starting it again after successfully updating works around this.

This error has occured every time VS Code Server tried to update in the past two months (so far, that's been ~5 times).

Thanks for letting me know! Sounds like a pain, I will see if I can fix it. I haven't been able to reproduce the error. In what environment are you running this? I could probably try keeping the expected files the same, or find a better moment to change the files, or in the worst case just add a timeout (not a fan).

Same problem here, may I attach some logs here in case it helps:

My observation is VSCode will attach an epoch before the update completes (refer to the path above, ending with a80e2d21-1680770145), may this can be utilized?

Before enabling the auto-fix-vscode-server.service try running vscode. This will fail as expected but after that you can run the auto-fix-vs-code-server-service.

Hope this fixes the issue for anyone going through it.

I moved the extra files that were added to the root of the install path, similar to what it itself does for the log and token file already. It might still fail due to me changing node, but if it doesn't, this hopefully fixes the issue.

@niklaskorz @ykis-0-0 @Jumail Can any of you verify whether it now works for you without it first failing like @Jumail mentioned?

[niklaskorz]

So this issue seems fixed now (thanks a lot!), but somehow VS Code can't connect to the remote server now... This might be more related to NixOS WSL though instead of this repo, I will dig some more to see what causes this.

Edit: Everything works! Thanks sooooo much. The last issue was a fault in my own NixOS config, so never mind that.

Thank you for getting back at me, I am glad it now works for you too!
