I am trying to download ros package ros-kinetic-desktop using
apt-get. I have set the sources.list and the authentication key as well. However, I am encountering an error that says:
Err:1 http://packages.ros.org/ros/ubuntu xenial/main arm64 ros-kinetic-desktop arm64 1.3.0-0xenial-20170303-020026-0800 404 Not Found [IP: 18.104.22.168 80] W: Can't drop previleges for downloading as file 'home/sam/ros-kinetic-desktop_1.3.0-0xenial-20170303-020026-0800_arm64.deb' couldn't be accessed by user '_apt'. - pkgAcquire::Run(13: Permission) E: Failed to fetch http://packages.ros.org/ros/ubuntu/pool/main/r/ros-kinetic-desktop/ros-kinetic-desktop_1.3.0-0xenial-20170303-020026-0800_arm64.deb 404 Not Found [IP: 22.214.171.124 80]
sudo apt-get download ros-kinetic-desktop is the exact command I'm using.
Can someone please help me to resolve this. Thanks in advance.
EDIT: I am not supposed to use
sudo apt-get update to update my entire cache ( especially the system packages) because the updated packages will crash my proprietary drivers. So, in order to just update the repositories I require, I manually added the ros repository to software and updates applet instead of using
apt-get update. This way I am able to directly install the ros packages using
install but unable to download them and manually install later.
