This thing is great. With the help of this video, the UBOSbox was easy to put together. After that, you follow some instructions on how to use the usb stick to boot up the system with Nextcloud for the first time.
So far, I have been using the NextCloud android app to sync photos from my mobile device to my UBOSbox. For now, I’m not yet giving my UBOSbox a public web address but I’m keeping in mind that there’s lots of potential as there are many open source apps like wordpress to choose from. You can make a request to add support for an app as well. And as Eben Moglen would say, I get to own and keep my logs.
