I can't guess what the keywords sudo apt update, docker and RaspiOS mean, so please give me some more details.
At the very least, I need your purpose and the reference URL of the cause of the error.

Keyword explanation:
"Sudo apt update": Command which is used to download package information from all configured sources
"docker": kind of an Virtual machine
"RaspiOS": Operating System used on the Raspberry Pi 4, in my case it's Raspios bullseye arm64

My Purpose is to install ROS2 on the mentioned RaspberryPi. So i dont understand why a missing ubuntu file is a problem.
Hope this helped you...

Here is debian (arm64) docker installation tutorial.

I checked it on an AWS server, but it probably works on Raspbian as well.

uname -a
> Linux ip-172-31-18-171 5.10.0-14-cloud-arm64 #1 SMP Debian 5.10.113-1 (2022-04-29) aarch64 GNU/Linux
