Hello Kunbus Team,

the docker setup tutorial https://revolutionpi.com/de/tutorial/docker has a flaw, in step 3 there should be no duckfoots at the $VERSION_CODENAME.
-> this would be correct:

Code: Select all

echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/debian $(. /etc/os-release && echo $VERSION_CODENAME) stable" | \sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Hello Benjamin!

Thank you very much for reporting this issue with the Docker tutorial documentation.
You're absolutely correct, the problem is indeed with the quotation marks.
The current documentation shows German-style quotation marks („ and ") around $VERSION_CODENAME, but it should use standard double quotes (") for proper shell syntax.

I'll make sure this gets reported to our documentation team for correction.
Thank you for taking the time to identify and report this!

I have opened a merge request with the correction in our documentation.
This will be updated soon.
Thanks again, Benjamin!
