Cannot install any app

Question

I am a new Elementary OS User, and I have a problem.

I could install apps before, but since I tried to install Spotify following this tutorial, I am getting an error message each time I try to install any app. Here's a picture of the error message:

Any way to fix this?

Thanks.

EDIT: The result of the cat command is two lines of text, and both say "sudo apt-get update".

Answer 1

I'm nearly sure you didn't install Spotify correctly. At least that spotify.list file isn't correct so you need to remove it in order to install any other thing.

sudo rm /etc/apt/sources.list.d/spotify.list

Then update your package list to make sure it works again:

sudo apt update  

Answer 2

please can you give us more and better details:

• provide the link of the tutorial you followed (the link is a downsized image - thumbnail)

• open a terminal and write the following command and then show us what it says

  sudo apt update & sudo apt upgrade

• again, open a terminal and write the following command and then show us what it says

  cat /etc/apt/sources.list.d/spotify.list

it looks like you have a failed gimp installation and that image isn't showing us all what's happening sometimes a previous faulty installation does not allow another one until it's fixed, but the image showed us that you have the command sudo in a sources.list file, that's wrong and you should fix that

you can install the latest spotify using snapd https://snapcraft.io/spotify

Use this command, you did something wrong following the tutorial and the file is wrong

sudo rm -fr /etc/apt/sources.list.d/spotify.list

If you want to install spotify, use snap https://snapcraft.io/spotify If you don't have it (snapd) follow the link https://docs.snapcraft.io/core/install-elementary-os
