ssh agent forwarding faulty

[0x7231636b]

Trying to use git with ssh keys within the devcontainer (git extension or terminal) does not work.

In a terminal in VSCodium connected to a devpod container typing ssh-add -l should show the list of my loaded ssh keys passed through from my host machine. But it is not able to show anything, it seems that there is a local ssh agent running instead of the forwarding to the host machine.

Further investigation was even more irritating, when investigating the devpod with ssh project.devpod and then typing ssh-add -l (within the container terminal) I was able to verify that in fact the devpod itself forwards the ssh related stuff from my host machine.

This left me confused since I assumed that I only connect to the container itself and all things in VSCodium from then on are executed directly within the container (like I did with connecting manually into the container while troubleshooting).

tl;dr

ssh-add -l shows different results depending on the way I am connected to the DevPod container.

machine	command	result
host	ssh-add -l	Key ABC
devpod container (connected via ssh shell)	ssh-add -l	Key ABC
VSCodium devpod container session terminal	ssh-add -l	Error connecting to agent: No such file or directory

The user within the container is root, and it is in fact the same (and only) container I can connect to, so I expected the same resuts.
