There is no sound in my system speakers.
I tried "inxi -SMA" in my terminal and it showed like this.
It shows two sound devices in the audio in the section, one is Intel and another is Nvidia.

Hello everyone,
I recently did an "apt update" from terminal and afterwards i started receiving these warnings:

W: Skipping acquire of configured file 'contrib/binary-amd64/Packages' as repository 'http://security.ubuntu.com/ubuntu focal-security InRelease' doesn't have the component 'contrib' (component misspelt in sources.list?)
W: Skipping acquire of configured file 'non-free/binary-amd64/Packages' as repository 'http://security.ubuntu.com/ubuntu focal-security InRelease' doesn't have the component 'non-free' (component misspelt in sources.list?)
full log
sources.list

I don't really understand what the issue is and how to get rid of these warning.
Thank you in advance!

EDIT:
To be more specific:
I was trying to install libncurses-dev but for some reason it was not available so i did the following steps:

• Enabled sources on software-properties-gtk
  
• Changed mirror location
  
• Updated from terminal
