As you can probably tell by the title, I'm a complete novice in Linux environments.

Trying to work out how to install apps using sudo apt-get install. I have been able to install some, but recently it started to fail.

For example I'd like to install elementary-tweaks, but the error message is the same, for all E: Unable to locate package elementary-tweaks

I THINK I understand that if I add a PPA I should access the packages associated with that PPA.

Therefore I have tried removing previous PPAs (as seen on some answers on this site), and add this: https://code.launchpad.net/~versable/+archive/ubuntu/elementary-update followed by a sudo apt-get update.

I have also tried sudo apt-get -f install, PPA purge, etc...

Still, the error message remains.

Error message:

Reading package lists... Done
Building dependency tree        
Reading state information... Done
E: Unable to locate package elementary-tweaks

Could anyone please point it out for me, what am I missing in this? Also that what is a possible resolution to similar cases?

Thanks!

That's should work for any Elementary OS, the proper way to add ppa

sudo apt-add-repository ppa:versable/elementary-update
sudo apt-get update
sudo apt-get install elementary-tweaks

So .. If that not work then update the Q with the Error

  1. Backup your /etc/apt/sources.list file first

    sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup

  2. Edit your /etc/apt/sources.list

    sudo nano /etc/apt/sources.list

  3. Copy/paste the content below and save /etc/apt/sources.list file

  4. Update the apt

    sudo apt update

  5. Try installing your app again. For example:

    sudo apt install snapd

make sure you're in the home directory. just close out the terminal and open a new terminal window.

via https://launchpad.net/elementary-tweaks:

sudo add-apt-repository ppa:mpstark/elementary-tweaks-daily && sudo apt-get update && sudo apt-get install elementary-tweaks
