Hi! I was trying to install ERPnext by setting up frappe bench but was
unable to do so. I tried the Easy way and got the following error
W: Failed to fetch http://ppa.launchpad.net/libv4l/ppa/ubuntu/dists/trusty/main/binary-i386/Packages 404 Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.
Output of cat /etc/lsb-release is
