Hi, we got a problem installing the demo env on ubuntu. We already installed docker twice and did all the prerequistes mentioned here: https://docs.spryker.com/docs/scos/dev/setup/installing-spryker-with-docker/docker-in[…]-prerequisites/installing-docker-prerequisites-on-linux.html Nevertheless we get an error at

docker/sdk boot

genrsa: Can't open "/data/deployment/context/ssh/private.key" for writing, Permission denied%

When running it without sudo. When running it with sudo, the boot succeeds, but the

docker/sdk up

fails with:

chmod: changing permissions of '/data/config/Zed/dev_only_private.key': Operation not permitted
chmod: changing permissions of '/data/config/Zed/dev_only_public.key': Operation not permitted

Has anyone an idea, what we could do here?

After doing all the prerequisites, did you restart the host OS? Like after you added docker to the group etc.

Ok, we solved by removing all packages that were remotely connected to docker and reinstalling everything from the scratch.
