How To Fix Duplicate sources.list entry

if the following error occurs..

Duplicate sources.list entry http://dl.google.com/linux/chrome-remote-desktop/deb/ stable/main i386 Packages (/var/lib/apt/lists/dl.google.com_linux_chrome-remote-desktop_deb_dists_stable_main_binary-i386_Packages

change the name one of your sources list by doing the following commands...

cd /etc/apt/sources.list.d


ls


in my case it displayed this lists


chromeos.list chrome-remote-desktop.list dropbox.list google-chrome.list google-chrome.list~


rename the chrome-remote-desktop..


sudo mv chrome-remote-desktop.list /etc/apt/sources.list.d/chrome-remote-desktop.list.bak


run ls to check if you renamed it successfully

 ls
chromeos.list chrome-remote-desktop.list.bak dropbox.list google-chrome.list google-chrome.list~


then run...

sudo reboot
