"sudo apt update" and all I get is (target content is configured multiple times), (the repository does not have a Release file), (404 not found)

Question

this is my first time to install linux on my system, I think there is a lot of mess here and I feel helpless from too many errors I got when trying to update my system, when use terminal with this command:

sudo apt update

I got many errors specially from these 3 types:

1. (target content is configured multiple times)
2. (the repository does not have a Release file)
3. (Err 404 not found)

knowing that I searched many topics and couldn't solve the problem with my system.

Here's the output I got after writing "sudo apt update"

Solution 1

The error/warning output of repository update command is related to your repository settings. The settings reside inside /etc/apt/sources.list.d/<file> and /etc/apt/sources.list.

First of all you should comment out all repositories located at cdrom since you really don't want to use packages out of your CD-ROM installation media...

The rest of errors is related to either unsecure connection (plain HTTP) or just the repository being dead (404, Release file). You should probably do the same as with the cdrom ones - comment them out.

Solution 2

The output is simply a warning that you have the same entry in the main sources.list file and in a special file named google-chrome.list. You can live with it or remove the file, as it is unneeded.

To do so, open a terminal and run

sudo rm /etc/apt/sources.list.d/google-chrome.list

then run

sudo apt-get update

then run

sudo apt-get upgrade

Hope it's help you.

Solution 3

I had a similar issue, and here's the error that was been displayed multiple times

W: Target Packages (non-free/binary-amd64/Packages)
is configured multiple times in /etc/apt/sources.list:51 
and /etc/apt/sources.list.d/opera-stable.list:4

I fixed it this way

1. Enter the command below in your terminal

   sudo nano /etc/apt/sources.list

2. Comment out the line that is causing the issue.

3. Save your changes.

thanks my friend, but excuse me I'm still new with linux, how to comment out repositories located at cdrom

[Yuri]

Open and edit the repository settings files. Disable all repositories pointing to the cdrom by prepending a comment mark. The comment mark is # as stated in the docs linux.die.net/man/5/sources.list.

What makes you think that a 404 and missing Release files on a repo is caused by a VPN?
