Failing re-install Zabbix agent

[ZabbixUser2020]

Hi there,

installed Zabbix agent (4.0) on Ubuntu 16.04, but noticed agent is off. Once I enable it, it stays as running for a minute or two and is off again.

Decided uninstall (by this link http://ashoktutorials.blogspot.com/2...om-ubuntu.html) and install again, but now is failing installing back:


what can be done so I could re-install it again?

Look at the first line of messages that systemd has reported from the failed startup of zabbix-agentd. zabbix-agentd is telling you that your agent configuration file is missing required settings. Fix the config file so it's appropriate for your environment, and try again.

I have added necessary value sin config file, same.
So eventually tried one more time to completely remove and install. Now I am failing to install it:
1. This went fine:

wget https://repo.zabbix.com/zabbix/4.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_4.0-2+xenial_all.deb

2. This part is failing now:

dpkg -i zabbix-release_4.0-2+xenial_all.deb

Error:
dpkg-deb: error: 'zabbix-release_4.0-2+xenial_all.deb' is not a debian format archive
dpkg: error processing archive zabbix-release_4.0-2+xenial_all.deb (--install):
subprocess dpkg-deb --control returned error exit status 2
Errors were encountered while processing:
zabbix-release_4.0-2+xenial_all.deb


please help

If you get an error saying that the file is not a debian format, the file may be corrupt. Please download and install again. There is a newer version of the package, so you may want to use it.

$ wget https://repo.zabbix.com/zabbix/4.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_4.0-3+xenial_all.deb
$ sudo dpkg -i zabbix-release_4.0-3+xenial_all.deb
$ sudo apt update
$ sudo apt install zabbix-agent
$ sudo vi /etc/zabbix/zabbix_agentd.conf
$ sudo systemctl start zabbix-agent
