Summary

Hi guys,

I have fresh installed VS Code and try to install the Powershell extension from MS. Unfortunatelly there is just an error, that the downloaded Zip is corrupted. No infromation about which URL was accessed, nor where to find the corrupted Zip File... Any ideas? Other extensions, like the "poweshellprotools" installs with not problems.

I would try restarting VS Code, clearing any cache it has if possible, and trying again. My guess is it just got corrupted when downloading (like a transient network or disk issue), as I haven't otherwise heard of this being an issue (and I would expect to given the amount of users it has).

[dramerus]

I also have this issue, with both my local and portable installs. The only resolution that seemed to work was manually downloading the .vsix file and installing it that way.

Waiting to see if it will upgrade with the next release or if I'll need to manually upgrade moving forward.

[Mehdi-Dehghan]

I've been having the same issue with any extension and I tried to use downloaded .vsix files. but the vscode showed "end of central directory record signature not found"!

[andyleejordan]

Interesting...I'm trying to get a new pre-release out today for you guys to try. I wonder if just a bad upload happened.

[andyleejordan]

Hey all, a new pre-release is available. Can you try again?

Thanks!

[andyleejordan]

Since this recently changed (the separate "Preview" extension is no more) that means going to the "PowerShell" extension in the marketplace within VS Code and clicking this "Switch to Pre-Release Version" button:

[alexanderarnst]

Hi guys, thanks a lot for your help. Unfortunatelly there is still the same error, installing the „Pre-Release“ Version. ***@***.*** Any idea? Thanks a lot again to you all and Andy! ☺

[andyleejordan]

Hm...what happens if you download the VSIX file from here: https://github.com/PowerShell/vscode-powershell/releases/tag/v2023.3.2-preview

and install it "manually" that is in the VS Code Command picker, choose "Extensions: Install from VSIX" and then point it to the downloaded VSIX.

[andyleejordan]

So this looks eerily similar to issues reported with the Python extension here microsoft/vscode-python#17491 and upstream here microsoft/vscode#131022. The only extension dependency we have is the built-in "powershell" extension (that just installs a basic grammar, and is part of VS Code). I'd like to follow their guess about corrupted downloads in VS Code's user data folder.

So a way to test this would be to open Code from the command line with a flag like this: code --user-data-dir <some random test folder> so that Code opens with a fresh (and empty) user data directory.

[alexanderarnst]

Hmm, the VSIX file remains 0 byte of size. Probably there is some restriction in our company network? Best regards,, Alexander Von: Andy Jordan ***@***.***> Gesendet: Dienstag, 28.

[andyleejordan]

Ahh, interesting. I'm sorry about that! I can't think of a good workaround other than contacting your IT department and explaining you need to download VSIX packages as part of your workflow.

[dramerus]

I ran into two issues here:

The only way this worked for me was using both the powershell-2023.3.2.vsix and bypassing the existing user data folder as @andschwa suggested.

Assuming the issue is in my VS Code User Data folder, does this mean I will have to download all my extensions again to a fresh folder?

[andyleejordan]

@dramerus if you're at least able to download the VSIX, then I think your issue is just a corrupted download in your existing user data folder. I'm...not sure how to fix that. Theoretically you could clear VS Code's cache? I'd try checking its user data folder for anything mentioning "extensions," deleting them, and then reinstalling them (you could be extra careful and just try to delete the PowerShell extensions). Hope that works! Fortunately it's not a huge deal to re-download extensions, as their settings are saved separately (in your user settings.json file).

[MarkoCharqueno]

I was able to work around this issue by deleting the following folders .
C:\Users\UserName\AppData\Roaming\Code\CachedExtensionVSIXs
C:\Users\UserName\AppData\Roaming\Code\CachedData

Attempting to download and install the VSIX directly produced the same error, so I assume vscode ignores the download if there is already a VSIX cached.

I am building out a new system, clean install of everything, and am running into the same issues with trying to install the PowerShell module in VSCode. Trying all of the suggestions above, I am continually getting the "Corupt ZIP: end of central directory record signature not found" error.

I am able to download the VSIX clean (I think) but even the manual install of it does not work, even after uninstalling all other extensions (Git Graph was the only other installed so far) and deleting anything that looked like cache in the AppData\Roaming\Code folder. Even starting with code --user-data-dir <some random test folder> made no difference.

On my old system, about a month ago I noticed the PowerShell extension needed an update, and I have not been able to get it to install on that system either. I was expecting a clean install to work, but is seems to be something with VSCode or the PowerShell extension file.

Any help would be seriously appreciated.

Can you verify the contents of the VSIX? You can view the size it ought to be here: https://github.com/PowerShell/vscode-powershell/releases/tag/v2023.3.3

Seems like this issue is mostly related to firewalls causing the VSIX not do download fully.

[JamesAMartin]

andschwa,

You are spot on with your suggestion. I should have checked file size on the download, but as everything appeared to work properly, I did not suspect an issue. It turns out that our firewalls were updated to protect against a vulnerability from a few months ago, and that has not been lifted yet. It specifically targeted the PowerShell VSIX, but the firewalls were not updated after the vulnerability was fixed. I've got network guys looking at it now.

Why the firewalls would allow any part of the file to download and not throw an exception to the user is a different question...

Thanks for the quick and excellent assistance!

[andyleejordan]

And I sure am curious why they specifically blocked the PowerShell VSIX...I don't have any reports about vulnerabilities.

[JamesAMartin]

I have gotten a little more detail from our network guys...

We are using Palo Alto firewalls, and it appears they setup the initial restriction to help protect our systems. Details of the vulnerability can be found at GHSA-pw56-c55x-cm9m.

Summary is below:

Oh, I see. So it's a blanket ban on allowing VS Code to download VSIXs (meaning it breaks ours and all other non-built-in extensions). Fortunately, according to that CVE it was patched back in October 2022. As long as your VS Code version v1.73.1 or above it's no longer a threat. Since VS Code auto-updates, and you're likely already on the latest (1.77.3), your IT team can probably be convinced to allow VSIX downloads again (and thus allow marketplace extensions to be installed).

Affected versions
v1.4.0 - v1.71.1
Patched versions
v1.73.1

The only thing I don't get is why they blocked VSIX downloads...like, it doesn't have anything to do with the CVE as far as I can tell. That vulnerability existed in VS Code's built-in Jypiter Notebook's feature code.

[JamesAMartin]

The strange thing from my perspective, is that only the PowerShell extension seemed to be affected. All of the others I tried installed with no problem. Hopefully this will help someone else that has been bit by the same issue.

[andyleejordan]

That's so weird...once upon a time the PowerShell extension shipped some Jypiter Notebook code too, but it was removed over a year ago. Maybe it's just because it contains PowerShell scripts and modules? Palo Alto is being a bit too "helpful" I think.

[MarkoCharqueno]

I experienced this issue with the C# extension as well, but no other extensions. So not entirely isolated to just the PowerShell extension.

Same issue here just the powershell extension so far, with vpn off I am good.

This issue has been marked as external. It has been automatically closed for housekeeping purposes.

I've had the same issue with any extension and tried to use downloaded .vsix files. But the vs. code showed "end of central directory record signature not found"!
And that happens with any extension. Could it be a problem with my proxy?

code --version
1.80.1
74f6148eb9ea00507ec113ec51c489d6ffb4b771
x64

[andyleejordan]

Yes, it is most likely a problem with your proxy.

[afsneto]

I was able to work around this issue by deleting the following folders . C:\Users\UserName\AppData\Roaming\Code\CachedExtensionVSIXs C:\Users\UserName\AppData\Roaming\Code\CachedData

Attempting to download and install the VSIX directly produced the same error, so I assume vscode ignores the download if there is already a VSIX cached.

Thank you so much, that worked! Finally, I can update/install extensions!

This was an issue with the proxy on my end as well. Make sure you can connect to all (relevant) domains on this page.
