[ubuntu-base] [ubuntu-22.04] ssh keys don't work in ubuntu-base image

[brianwatersmanna]

I am creating a simple devcontainer based on the base images stored here.

I have tried two images:

• mcr.microsoft.com/vscode/devcontainers/base:ubuntu-22.04
• mcr.microsoft.com/vscode/devcontainers/base:bullseye

Using the bullseye image, ssh keys are passed from the host automatically.

In the ubuntu-22.04 image, they are not?

I have checked the ubuntu-20.04 image and they work fine also. Seems to be isolated to the 22.04 image?

Hi 👋

Thanks for reporting the issue. Looks like it's similar to the problem mentioned in #650 (comment)

@alexander-smolyakov Can you help investigate this issue? Thank you!

I just hit this same issue. It's very strange since I can see my keys show up in the vs-code terminal when i run ssh-add -l however when I try to do ssh -T git@github.com or any other git operations I get a permission denied (public key) error

Same with debian:bookworm. ssh-add -l correctly returns the identity but authenticating with git or ssh fails with an error message somewhere in the log: get_agent_identities: ssh_fetch_identitylist: communication with agent failed

It seems to be some kind of incompatibility with different OpenSSH versions, see also microsoft/vscode-remote-release#7525

Thanks @Roemer for pointing it out. Closing as this looks like an upstream issue!

Might be worth looking at microsoft/vscode-remote-release#7525 (comment) and upgrading OpenSSH for Windows.
