@dobey How should i go about determining which apps have a higher probability of working so im not just installing and crossing my fingers?

I tried Okular and gnome-dictionary and neither worked. I did get a calculator called qalculate to work. The docs only talk about installing and managing containers and apps, and search results haven't given me any idea how to go about troubleshooting this.

Nexus 5

Build number: OTA-8
Build Description: armhf (20190220)

Thank You

Did my best to get this post in the proper category. Want to make sure before i make the purchase. On ebay im seeing lots of d820's and some 5X models. Anything i need to stay away from?
