[Remote-SSH Bug]: The defaultExtensions setting does not respect the "remote.downloadExtensionsLocally" setting

Expected Behavior

When having the following settings on the client side:

    "remote.downloadExtensionsLocally": true,
    "remote.SSH.localServerDownload": "always",
    "remote.SSH.defaultExtensions": ["extension"],

And connecting to a server that does not have access to the marketplace, the extension should be downloaded from the client and then installed on the remote host.

Instead, it attempts to connect to the marketplace on the remote side and throws an error. Having "remote.downloadExtensionsLocally": true also set in the remote settings does not help.

Steps To Reproduce

1. On an internet/marketplace enabled client, set the local settings

    "remote.downloadExtensionsLocally": true,
    "remote.SSH.defaultExtensions": ["extension"],
    "remote.SSH.localServerDownload": "always",

2. Connect to a remote host that does not have internet/marketplace access
3. Expect "extension" to be installed correctly
4. See the error

Happy Coding!

That's the way the feature is implemented currently- it tries to install the extensions before connecting to your remote, so you don't have to do a reload, but then it can't yet do the download locally

I see, thanks. I wish I could contribute a setting to override this but sadly the extension isn't open source

[HunterDG]

+1 - current implementation kinda defeats the purpose of/negates the remote.downloadExtensionsLocally setting

[flying-sheep]

How do I circumvent this bug? Can I copy/extract extensions to some directory on the remote to install them?

[joshspicer]

@flying-sheep you could use the command shown below to manually install an extension you've copied to your remote machine

On a host that can download extension, you'd find them by default in $HOME/.vscode-server/extensions. Extensions in that form on disk can be installed with the command regardless of internet connectivity

There is a download button for extensions on the marketplace website,or you can take the copy from your local VS Code instance.

[jzyrobert]

@joshspicer In the latest pre-release Remote-SSH extension it now adds a setting called remote.SSH.defaultExtensionsIfInstalledLocally which is non-empty by default:

This then causes connection attempts to remote hosts without Internet access to fail due to the issue raised here. Could you please ship this setting to be empty by default, or at least allow for a fallback if marketplace.visualstudio.com cannot be reached rather than failing the connection and having to remove the entries manually?

Thanks

[joshspicer]

Thanks for the feedback @jzyrobert, I will remove the defaults.

The latest insiders will automatically do what 'downloadExtensionsLocally' does for 'defaultExtensions' (if they first fail to be installed on the remote)

[joshspicer]

Testing steps:

• Set up a remote host that does not have access to the internet. The remote needs to fail to download extensions from the internet to trigger this fallback. - Option 1: Here's a docker configuration that should work as your "remote" machine that you SSH to. - Option 2: Easy way to do this on a linux box is install ufw (uncomplicated firewall) and run the commands:

sudo apt install ufw   # or similar for your distro
sudo ufw status allow 22
sudo ufw default deny outgoing
sudo ufw status verbose # check your firewall rules (make sure you don't block inbound ssh!)

sudo ufw enable

• Ensure you don't have any extensions cached on your remote by deleting ~/.vscode-server-insiders on your remote machine
• Add some marketplace extensions to the remote.SSH.defaultExtensions setting
• Connect to the host with Remote - SSH.
• Confirm that the extensions eventually appear installed

You'll see similar messages in the window log (please share verbose window log if any issues arise!)
