Hello,
I am the main developer of NextCloudPlus. NCP is a community project to make it easier to run and setup a Nextcloud instance in ARM boards, by providing configuration tools and setup wizards for typical management tasks such as backups, SSL certificates and more.
We have just released the first stable version of Armbian based images with NCP for Odroid XU4 / HC1 / HC2.
Check it out at the downloads section. More boards will come soon
