So i tried to update my package and here its says that

Err:9 https://download.docker.com/linux/debian hirsute Release 404  Not Found [IP: 108.158.251.124 443]

so what does this problem exactly mean and how to solve this? and i am newbie in linux so please tell me what does this "doesn't have release file mean"?"s not have a Release file. N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details. " and and what does this mean too?

First, you should upgrade to Ubuntu 21.10, since 21.04 is out of support.

Then, your repo string is wrong. The Docker repo for Ubuntu Impish should be: (after you upgrade to a supported release)

deb https://download.docker.com/linux/ubuntu impish stable

So you should edit your sources.list to have the correct string. The source file will most likely be either /etc/apt/sources.list or /etc/apt/sources.list.d/docker.list.
