Issue after .24 upgrade nextcloud/php issue

roundcube works, but I get the following for /cloud

This version of Nextcloud requires at least PHP 5.6.0
You are currently running 5.5.9-1ubuntu4.22. Please update your PHP version.

~> which php /usr/bin/php ~> /usr/bin/php -v PHP (cli) (built: Sep 28 2017 16:33:02) ( NTS ) Copyright (c) 1997-2017 The PHP Group Zend Engine v3.0.0, Copyright (c) 1998-2017 Zend Technologies with Zend OPcache, Copyright (c) 1999-2017, by Zend Technologies

I’m not sure what to look at next

Try a dist-upgrade on the php package? Or maybe reinstall MIAB?
