Installed from Armbian_5.65_Odroidxu4_Debian_stretch_next_4.14.78.

Used Armbian-Config to install ISPConfig

Used ISPConfig to install Joomla

Joomla control panel states version is 7.0xxx but requires 7.1 or later - 

We have detected that your server is using PHP 7.0.30-0+deb9u1 which is obsolete and no longer receives official security updates by its developers. The Joomla! Project recommends upgrading your site to PHP 7.1 or later which will receive security updates at least until 2019-12-01. 

apt update apt upgrade shows all packages up to date

 

Is there a way to upgrade to 7.1 in this config? all the help I find online is oriented toward x86 hardware.

Ignore warning? appears to be working but the security warning bothers me.

Which you can use until they provide ARM binaries. This goes on the advanced level, far away from Armbian. Check this: https://www.howtoforge.com/tutorial/how-to-install-php-7-on-debian/

I am not sure anyone can help you here. Better try here: https://www.ispconfig.org/support/

For better support of PHP please install  Armbian_5 65_Odroidxu4_Ubuntu_bionic - new PHP packages are in Ubuntu!

OK cool thanks I was using Stretch.
