Just a quick status update. We are still working on this, support of PHP8 appeared to be much more complex than initially thought. No ETA yet.

Hello,
Please advice when approximately users will be able to install Zabbix 6.0 LTS on new Ubuntu 22.04 LTS release?
Thank you beforehand

I already upgraded to  Ubuntu 22.  It has PHP 8.1.  Now the web frontend for zabbix doesn't work.  Oops.  Should have checked more carefully.

No ETA yet.

Here we are nearly 3 weeks after saying No ETA. Is there any ballpark ETA now?

This is what I am currently getting from the 8.1 version of php-fpm being called by Apache 2.4.  This is after logging in, which SEEMS to work.  My zabbix version is "1:6.2.0~alpha2-1+ubuntu20.04" installed from the zabbix APT repository.

Is there some kind of fundamental difference in how PHP 8.1 handles includes compared to older version?  The CMessageHelper class file appears to be there.

elyograg, indeed PHP 8.x is fundamentally different comparing to previous releases. We want to keep our  code as strict and safe as possible, this requires manual review and additional testing. Some things cannot be automated unfortunately. I will try to update on ETA later today.

6.2.0~beta1 dropped on the ubuntu repo, and now my zabbix frontend works again.  Thanks for your efforts!

Let me note my observation:
on PHP8.0  zabbix 6.0 mostly worked. I could spot that IT services have some issues and global server status did not work, but most of the things worked.
But PHP 8.1 is different - any frontend page generates a lot of errors.

Some Zabbix docker images are prepared to use PHP 8. I recommend do not use "latest" tag, use specific version instead. When 6.0.5 will be released Zabbix will be ready for PHP 8.0+.

Hello,
Please advice when approximately users will be able to install Zabbix 6.0 LTS (server + front-end)  on new Ubuntu 22.04 LTS release?
Thank you beforehand 

Documentation updated:

• Requirements page for versions 6.0, 6.2 and 6.4.
• What's new in 6.0.6

Is this only about PHP 8.0 support, or about the JIT too?  

I don't see anything in the "updated¨ documentation about JIT
