On these days, I’ve been trying to update at least my Firefox or chromium in the Ubuntu 12.04.1 because they work so slowly and everything I found was using terminal command sudo apt-get upgrade or update. I tried that but what my console was showing me has nothing to do with what I saw on a few tutorials, can anyone explain why this is isn’t working?

Pd: I suppose my Ubuntu version is pretty old

Try "sudo bash -l" to check if it is a problem related to the terminal or sudo.

The warnings should only matter in an graphical tool, apt-get shouldn't report these as it's text driven.... So either it's the terminal or sth. very funky.

Though if it's really Ubuntu 12.04… I'd recommend a fresh install, cause currently we're at 22 (LTS)

Are the package repositories even up any more? Maybe they've moved to https://old-releases.ubuntu.com/

I'm not sure why you'd want to run such an old release.

So you actually run a distro from literally a decade ago? Reinstall with something current or do incremental updates till you reach at least current LTS.

@electrineer cuz it was a computer I was given and haven’t used too much, I ve been always a windows lover but recently I decided to give it a chance, just for some programming projects or blender stuff, so I was wondering if I could update my browser.

@Oktokolo @IntrusionCM For now, I was wondering if I could update some programs specifically in order to search some tutorials and learn about it. Thanks for your help. Maybe If I couldn’t,I ll just upgrade it to Ubuntu, linux mint or guadalinex edu next…

@IntrusionCM I tried that but it gives the same result. Thanks for your help anyway

@Alexx16 Why?! You have Internet access. And if you want to learn how to get ancient systems back up to date that is fine.

But start with getting the package manager to work again. Might have to do incremental OS version upgrades because of breking changes preventing a one-step-upgrade. Might need to configure URLs of archived repositories and update public signing keys manually.

Might be a lot of hassle for a skill you hopefully will never need again. I would recommend just installing something fresh (backup your data first).

Yeah, at that point, upgrading everything will be way too much work that might not even be successful in the end. Just back up your data (which you should do anyway) and install a new one.

I can recommend Mint 21 Cinnamon, which is a better Ubuntu 22.04.

@Oktokolo @Fast-Nop thanks for all your help, I will try my best

It is so EOL that apt should not work anymore. The packages are no longer up for grabs. Even with the paid extended support, it ended last year.

You don't have to expose yourself to security risks like that. Ubuntu upgrades are free.
