E: The repository 'https://download.docker.com/linux/ubuntu ara Release' does not 
have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled 
bydefault.
N: See apt-secure(8) manpage for repository creation and user configuration details.

Answer 1

Warning: I'm new to Linux so I'm not entirely sure this is correct, but it worked for me.

Someone in another thread mentioned that his ubuntu mint documentation/version(?) didn't assign the right files by default and he had to change it. Then it dawned on me that Parrot OS isn't ubuntu at all. It's debian bullseye.

So it's probably the same mistake only for Parrot.

Then I changed the URL inside of

/etc/apt/sources.list.d/docker.list

to

https://download.docker.com/linux/debian bullseye stable

and it worked!

sudo apt update

stopped throwing errors and the installation finished as expected.
