I have been away for 4 months and when I started Ubuntu again there were 0 updates available. That seems very odd to me. I tried several times and always got that the same result: packages are all up to date. How can that be? Any suggestions?

Ubuntu 20.04.3 LTS - 64-bit - Gnome Version 3.36.8

$ sudo apt update

22.04 is around the corner, 4 months with no update is definitely possible. Especially when you seem to have only very few repos enabled. I have security, updates, backports, main, universe in addition to what you have enabled.

Update the local package information with `sudo apt update` then upgrade the packages with `sudo apt upgrade`

Restore default repository, I kinda miss focal-updates and focal-security. https://gist.github.com/ishad0w/788555191c7037e249a439542c53e170

Does this answer your question? [How do I restore the default repositories?](https://askubuntu.com/questions/124017/how-do-i-restore-the-default-repositories)

Your Ubuntu system did not delete the `focal-updates` and `focal-security` sources itself. Whatever reason you had for disabling/deleting those sources, it was unwise. Restore them, and don't do that again.

Thanks emk2203, Mark, nobody, user535733 and specially Someone for the copy-past command line. The update works now and the sources are complete. I don't know how the sources got deleted or disabled, make me worried about the safety of my computer. How can I check if my system got compromised?

@Patrick Awesome! Glad your sources are complete. You can accept my answer by clicking the checkmark button near the votes if you find it useful. I don't think that any application or programme has disabled the sources, it's done by a human being. Maybe you were following some tutorial and blindly ran a few commands in the terminal? Sometimes, while upgrading or updating the repositories are turned off... Are you having the repositories in `sources.list` or did you define a custom path for it? System disables the repositories if they are on custom paths while upgrading certain packages.

Seems like an issue with the repositories. Check if your mirror is up to date. Then follow these steps:

Open Software and Updates app.
```
sudo software-properties-gtk
```
As you want ALL the upgrades, I recommend enabling ALL the repositories:
Then change the mirror to "Main Server".
Update:
```
sudo apt update 
```
Then upgrade:
```
sudo apt upgrade
```

Here is a one line copy-paste friendly command for the above steps:

sudo mkdir ~/answer && cd ~/answer/ && sudo wget https://gist.githubusercontent.com/ishad0w/788555191c7037e249a439542c53e170/raw/3822ba49241e6fd851ca1c1cbcc4d7e87382f484/sources.list && sudo sed -i "s/focal/$(lsb_release -c -s)/" ~/answer/sources.list && sudo mv ~/answer/sources.list /etc/apt/ && sudo apt update && sudo apt upgrade  && sudo rm -rf ~/answer

It indeed may well be that all repositories were turned off for one or another reason.

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.
