Linux Debian 11 bullseye
W: Target Packages (main/binary-amd64/Packages) is configured multiple times in /etc/apt/sources.list.d/google-chrome-beta.list:3 and /etc/apt/sources.list.d/google-chrome.list:3
After Installing google you might begin to get above update error, Either expediently or package you have install have Google Chrome and Google Chrome beta packages or you tried to install both at the same time as it’s mention in the error both files are conflicting with each other
Solution:
Basically /etc/apt/sources.list.d/google-chrome.list and /etc/apt/sources.list.d/google-chrome-beta.list are identical files and trying to run same process at the same time therefore either of them has to stop processing.
Open editor of your choice and edit list.d files in your system. in my case I have decide to remove/disable google-chrome-beta.list as follow:
$ sudo nano /etc/apt/sources.list.d/google-chrome-beta.list
file will open in your nano editor as follow:
Add # to disable line 3 in other word I am disabling automatically configured file you can also navigate to list.d folder and remove this file either way the purpose is served
Press Ctrl + O to save file and Ctrl + X to exit editor
Now test your work by executing apt upgrade and update commands in Terminal window
Try with update command
If there is two files exist in the system and serving the same purpose can conflict with each other. The easiest and only solution in my opinion is to disable one and let other use the resources of your computer. This example can be use for any conflicting file errors.
There may be other ways to resolve this issue but I find this easiest and simple and would really like to know about your experience please use comment box bellow and share your knowledge with us.
