Upgrade ubuntu 18.04 to 20.04 without breaking Zabbix

[cnapan]

Does anyone know if I can do a release upgrade of Ubuntu 18.04 to 20.04 and my Zabbix 5.4 will still be working, or the upgrade will break something?

Later, I am planning to upgrade zabbix to 6.0, but need to know if Ubuntu upgrading itself won't damage anything.

First, I'd stop zabbix processes. Then you can try installing zabbix-release for ubuntu 20 from

https://repo.zabbix.com/zabbix/5.4/ubuntu/pool/main/z/zabbix-release/

"apt update" and then perform the upgrade. I have never tried it but I think it shouldn't break anything.
