You issued the wrong command here. Debian package manager works like this:
first, you update the list of packages with
apt-get update. This downloads a list of packages which a server currently has to a local file in
second, you install/upgrade packages from that list, using
apt-get install package_nameor
apt-get upgrade, respectively.
Your command jumps to step 2 right away and tries to install a software called
update which presumably doesn't exist.
