Trying to install OMV on Helios4 with armbian stretch.
First I try to install it from raspi-config, but it fails, then I try manualy — same results:
Source of problem was I install via armbian-config both OMV and nextcloud.
Nextcloud pull incompatible with OMV PHP version.
Solution — clean install, no nextcloud package in base system, use another host or docker for nextcloud.
