And this is my /etc/apt/sources.list:

Answer 1

main, universe, multiverse, restricted are different components of the Sections portion in a sources.list entry and can not be duplicated for a given entry (same Type (e.g. deb), URI (e.g. http://archive.ubuntu.com/ubuntu/) , Suite (e.g. xenial)).

In your /etc/apt/sources.list, you have duplicate components (main, restricted, universe) in lines 2 and 5:

deb http://archive.ubuntu.com/ubuntu/ xenial main restricted universe
deb http://archive.ubuntu.com/ubuntu/ xenial main restricted universe multiverse

As line 5 is a superset of line 2, you can remove line 2 using your favorite editor or use sed:

sudo sed -i '2d' /etc/apt/sources.list

Or comment out the 2nd line:

sudo sed -i '2 s/^/# /' /etc/apt/sources.list

Answer 2

Reset your repositories like this

1. sudo rm /etc/apt/sources.list
2. sudo software-properties-gtk
3. Pick your options
4. Save

Answer 3

This is issue with Ubuntu 16.04

You can fix it with xenial-backports

sudo apt install appstream/xenial-backports

sudo appstreamcli refresh --force

After the second command you will get

AppStream cache update completed successfully.

Answer 4

I have this problem too,I fix it through the error message:

"W: Target Packages (main/binary-amd64/Packages) is configured multiple 
times in /etc/apt/sources.list:2 and /etc/apt/sources.list:5".

you can sudo vim /etc/apt/sources.list.

then locate the second line, use # comment out the line.

save the file, and sudo apt-get update,the problem will be solved.
