I get this error when I try to update my Ubuntu 16.04.

Error:

W: The repository 'http://ppa.launchpad.net/upubuntu-com/network/ubuntu xenial Release' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
E: Failed to fetch http://ppa.launchpad.net/upubuntu-com/network/ubuntu/dists/xenial/main/binary-amd64/Packages  404  Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.

What is this error and How can I fix it ?

That error will do no harm (at least) but you can remove them manually by doing a sudo nautilus and then navigating to /etc/apt/sources.list and then delete the files not required , probably the files related to the upubuntu.com cause it doesnt have any files for Ubuntu 16.04 .
