I installed Linphone 3.3.2 from F-Droid, because it refused to install the latest version (marked “suggested” in the UI). When I tried to install as per normal, it downloaded, then just quit, with an error message saying “not installed”. Since I installed 3.3.2, the updates tab of F-Droid shows there is an update available for Linphone. But it won’t install. When I click ‘update’, I get the blue bar with “waiting to start download”, then after a few seconds it just quits with the “not installed” error message.
I have an ancient Oppo Android device running ColorOS 2.1, based of Android 4.4.4. I bought it because I thought it would be compatible with LineageOS, but I’ve been advised it’s the Chinese version, which isn’t supported. But incompatible apps are usually marked as such when I search, and I have “include incompatible versions” switched to “off”. So if 4.0.1 is incompatible, I would expect there would be no update notification, and 3.3.2 would be marked as “suggested”. If 4.0.1 is compatible, why won’t it install? I have 32GB of internal storage, and heaps of free space.
