XF 2.2 upgrade from 2.1 to 2.2 beta 4 commandline errors

[Marcel Broekema]

Got an error trying to upgrade from 2.1 to 2.2 beta4:

Running upgrade to 2.2.0 Alpha, step 29... done.
All upgrade steps run up to version 2.2.0 Beta 4.

In Xml.php line 31:

Class DOMDocument not found

In Xml.php line 31:

Class DOMDocument not found

xf:upgrade [--skip-statistics]

site unavailable after that. Did the same upgrade from 2.1 to 2.2 beta1 without this issue.
Any clue's here?

i guess problem solved, found out php-xml was not installed...

Presumably the PHP version on the server has been upgraded in the interim and that module was not installed by default.

You may want to check other functions which XF requires are also available (although there would likely be errors if they weren't).

You can use this script: https://xenforo.com/purchase/requirements-zip

Thx Brogan for your input, error has gone after installing php-xml, result was: Your server meets all of XenForo's PHP requirements.
So thats ok, using MariaDb 10.x
