Where to start debugging APK problems? [answered]
Am using an original Jolla, updated to 2.1, build 2.1.0.11
Have tried apk files for SolCalendar, Firefox (latest beta and last stable version) along with a Wi-Fi analyser, and none of them would install. No errors, just the "if nothing happens, then the package is probably faulty."
Firefox previously installed on Sailfish 1, so I have no clue about how to troubleshoot this. What files do I check, where, to find the reason for the install failures please?
