I cannot install some packages. So, I have tried "sudo apt-get update" and "sudo apt-get upgrade". These commands do not work, I get "IP not found":

I have read it can be something with the Ubuntu version. I don't want to upgrade to 22.04 if that means loosing all my files and configurations.

Ubuntu 21.10 (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/2022/07/19/ubuntu-21-10-impish-indri-end-of-life-reached-on-july-14-2022/ https://help.ubuntu.com/community/EOLUpgrades *Your issue relates to the release being EOL*

Once a release goes EOL, mirrors & 3rd party providers of packagers are free to *drop* support for it, so you've got whatever packages you had & made allowance for before the EOL date (*which was published at release time so you had warning*). The main Ubuntu repository just gets moved (see first comment), however country mirrors are *dropped*.

You've not said if you're talking about a Desktop or Server install, but the *release-upgrade* process does **not** erase your configs or data, and if a desktop system - you can re-install Ubuntu Desktop without loss of files too (ie. config changes you made survive, further *manually installed* packages from official Ubuntu repositories get auto-reinstalled too so you don't need to re-install those for Desktop installs).

It's a server install. I don't have any Desktop. So, the solution would be to upgrade to Ubuntu 22.00 by a release-upgrade process without losing any data, right? This would solve this problem? How can I do that?

Ubuntu releases are *year.month* in format, so 22.00 makes no sense. Refer to the standard upgrade instructions for 22.04 *jammyupgrades* doco (https://help.ubuntu.com/community/JammyUpgrades) and the EOLUpgrades I provided in my first link (or installing software from an unsupported release on this site)

@guiverc could you publish an answer so I can select it as correct one?

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.
