You can view here to find latest package:
http://repo.zabbix.com/zabbix/
See here for LifeCycle Policy, as they seem to post guides for installing packages that don't exist yet!

(When I first tried to install Zabbix, I was trying to use a URL from the guide that didn't work, and ended up getting an old version from Ubuntu repo) (3.4)
A Ubuntu Example:
http://repo.zabbix.com/zabbix/3.2/ubuntu/pool/main/z/zabbix-release/
You want the file "zabbix-release_#+{DISTRO}_all.deb"
Eg:
cat << 'EOL' >zabbix_agent_ubuntu14.sh #!/bin/bash #Zabbix Variables zabbixserver=192.168.1.255 hostname={HOSTNAME} #Latest Package URL latest="http://repo.zabbix.com/zabbix/3.2/ubuntu/pool/main/z/zabbix-release/zabbix-release_3.2-1+trusty_all.deb" #Install Zabbix Agent + Server + Pre-Reqs wget $latest dpkg -i zabbix-release*.deb apt-get update apt-get install -y zabbix-agent sed -i "s/127.0.0.1/$zabbixserver/g" /etc/zabbix/zabbix_agentd.conf sed -i 's,^\(Hostname[ ]*=\).*,\1'$hostname',g' /etc/zabbix/zabbix_agentd.conf service zabbix-agent restart EOL chmod +x zabbix_agent_ubuntu14.sh ./zabbix_agent_ubuntu14.sh
