apt package manager constant problems with sources

in flag

I have Ubuntu 20.04 LTS installed, and I am having constant problems with the package manager. Currently the issue is I am trying to install docker and it constantly fails because it cannot install the required packages. When I do apt update I get the following errors:

https://download.docker.com/linux/ubuntu/dists/focal/InRelease: No system certificates available. Try installing ca-certificates.

E: The repository 'https://download.docker.com/linux/ubuntu focal Release' does not have a Release file.

I have tried reinstallng ca-certificates to no avail.

I have had similar issues with the package manager in the past, for example when I tried to do a system update it gave me an error message that the package manager is broken, which was fixed by running

sudo apt install -f

It seems to me something is wrong with how the package manager is set up. What would the course of action be to reset/reinstall the package manager correctly? If this is not possible how would I go about identifying where the problem is?

I read the following at https://docs.docker.com/desktop/install/ubuntu/:

Prerequisites

To install Docker Desktop successfully, you must:

  • Meet the system requirements
  • Have a 64-bit version of either Ubuntu Jammy Jellyfish 22.04 (LTS) or Ubuntu Impish Indri 21.10. Docker Desktop is supported on x86_64 (or amd64) architecture. ...

Note that 20.04 is not mentioned, so I doubt it has anything to do with apt.

Thank you, I updated Ubuntu to 22.04, but I am still getting constant errors with apt. When trying to install docker I get`dpkg: dependency problems prevent configuration of docker-desktop: docker-desktop depends on qemu-system-x86 (>= 5.2.0); however: Package qemu-system-x86 is not installed.` .
I sit in a Tesla and translated this thread with Ai:

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.
