GhostCloud workaround for PinePhone

[mark1250]

So, due to some missing parts between UBports and Wayland you cannot setup online accounts on the PinePhone. Bug and Bug.

Here is a way to make it work until the bugs get addressed.

• We need to build a click package of GhostCloud. I setup a minimal Ubuntu 20.04 virtual machine as I use openSUSE and didn't want to try installing the click build environment on it. Then I setup the click build environment as described here. - I used the PIP method.
  
• Then following fredldotme's instructions, I built a click package of GhostCloud version 0.9.6 which does not use UBports online account mechanism.
  
• I transferred the click package to my PinePhone, and then using the UT Tweak Tool available in the Open Store installed GhostCloud.
  
• I was able to enter the URL, username, and password for my NextCloud instance. I now have access to files on my NextCloud server.
  
• For Calendar and Contacts, I setup syncevolution following the instructions on this github page.
  

I hope this will help others.
