Hello Zabbix TEAM,

I have some servers wants to monitoring in Zabbix-server 3.4, i have install Zabbix-agent 3.4 from this link :
https://www.zabbix.com/documentation/3.4/manual/installation/install_from_packages/debian_ubuntu

There is some week, i greatly installed the agent on different server, but to day, in a new server, i have this mistake when i want to update the repository :
W: Failed to fetch http://repo.zabbix.com/zabbix/3.4/debian/dists/jessie/InRelease Unable to find expected entry 'main/binary-armhf/Packages' in Release file (Wrong sources.list entry or malformed file)

E: Some index files failed to download. They have been ignored, or old ones used instead.

When i uncomment the second lines in zabbix.list files deb-src, the apt update works fine, but i can't find the zabbix-agent package in apt install zabbix-agent.

can you please see this issue and let me know what mistakes in this ?
Thanks !
