I'm getting the same error when trying to connect to a Debian 9 server.

Local PC SSH version: OpenSSH_8.0p1, OpenSSL 1.1.1c 28 May 2019

Remote system SSH version: OpenSSH_7.4p1 Debian-10+deb9u5, OpenSSL 1.0.2q 20 Nov 2018

Does this extension require the local PC and remote to be running the same version of SSH?

EDIT: I installed the official version of VSCode from AUR, rather than the open source version provided by the Arch community package repository, and it works now...

$ yay -S visual-studio-code-bin

The same as above, this extension does not work with vscode-oss version in Arch repositories. Official binary does.

Hi, the same happens here as well.

I just want to point out, this is not a WSL issue, but SSH issue. I do understand, that ArchLinux build is officially unsupported, but it would be nice to be able to use this extension anyway

[Sun1ive]

+1 running this issue as well
OS: Arch Linux x86_64

[BrutalBirdie]

Same here.

4.19.84-1-MANJARO

Installed visual-studio-code-bin 1.40.1-1 from AUR and now it's working.
https://aur.archlinux.org/packages/visual-studio-code-bin

[sizzlorox]

Can confirm installing via AUR solved this issue for me.
$ yay -S visual-studio-code-bin

4.19.85-1-MANJARO

[madewild]

Same for me on Arch

5.3.11-arch1-1

[roblourens]

It sounds like this has been resolved? Someone please let me know if not. That error can also be seen when the remote doesn't meet the linux prereqs: https://code.visualstudio.com/docs/remote/linux#_remote-host-container-wsl-linux-prerequisites

Still exist when using vscode-oss

[roblourens]

It's not possible to use remote with vscode-oss, since remote relies on non-oss components.

[Hubro]

It's not possible to use remote with vscode-oss, since remote relies on non-oss components.

That's fine, but the current error message is still not acceptable. At the very least there should be a proper error message that explains that the plugin doesn't work on the OSS version.

[kido5217]

It's not possible to use remote with vscode-oss, since remote relies on non-oss components.

Can you please clarify what are those components?
