Upgrade to 2.8 using Ubuntu Server 22.04.4 LTS

[John Coquitlam]

Good afternoon,
We are currently on AtoM 2.6 and would like to upgrade to 2.8
Our server staff asked if we can use Ubuntu Server 22.04.4 LTS.
We have not found any posting discussing this.
Will this still work?

Thank you
John

Hi John, 

It will *probably* work, with a bit of work on your PHP version - but please be aware that AtoM 2.8 has not been tested on an Ubuntu LTS release higher than 20.04. 

Currently the AtoM Maintainer team is working on a 2.9 release that should address a number of dependency upgrades, including: 

• Support for Ubuntu 22.04
• Upgrade to PHP 8.x
• Either upgrading or replacement of the current v5.6 Elasticsearch index
• Final removal of the legacy Bootstrap 2.x theme - with 2.9, only the new BS5 theme will be supported (meaning any users with an older BS2-derived custom AtoM theme will need to upgrade their theme before they can upgrade to 2.9)

There is no firm release date for this yet, but I suspect it will be a while (closer to the end of this year perhaps), given the number of dependency upgrades they hope to undertake.  

AtoM 2.8 will definitely not work with PHP 8.x now, meaning if you choose to try installing with Ubuntu 22.04 now, you will likely need to manually downgrade your version of PHP to 7.4, as I believe the default installation version in 22.04 is higher than that. 

That same caution may need to be applied to any other package installs - you will need to check the versions provided by default in 20.04, and make sure it matches in 22.04, or else manually downgrade if there are any breaking changes between versions. In general, I suspect that PHP is the biggest issue however, so if you downgrade that immediately, there is a chance the rest will work - I just don't know, since we haven't tested it ourselves! 

So: TL;DR: downgrade PHP for sure, otherwise proceed at your own risk, and if you encounter issues, review the installed package versions and dependencies. 

If you do proceed with 22.04, let us know how it goes!

Cheers,
