problem while updating package

in flag

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?

Ubuntu 21.04 (along with all flavors) is *End-of-Life* and thus unsupported on this site (https://askubuntu.com/help/on-topic), and many other Ubuntu sites, unless your question is specific to moving to a supported release of Ubuntu. https://fridge.ubuntu.com/2022/01/21/ubuntu-21-04-hirsute-hippo-end-of-life-reached-on-january-20-2022/ https://help.ubuntu.com/community/EOLUpgrades

That source provides support for Debian releases only if you look, open the link up with a browser & peek in the dists/ folder for supported releases. You'll quickly note **no** Ubuntu support is provided there, but I hope your box is offline given some patches for *hirsute* were dropped as it reached EOL prior to their time required to be in -proposed was completed; users having got their patches post-upgrade to 21.10 or *impish*.

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.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
