In the answer to this question I specifically discovered that I could not install the VLC nightlies. It had nothing to do with that answer, which was on a question about which version of VLC was right for that device. But that question was in fact inspired by this problem: I never previously had an APK I couldn't install by merely downloading, when I am in the Android Web Browser, and it downloads the APK, I can click on it in the notification applet at the top. When I do, it says
Can not open file
When I open that file up with the linageosLineageOS Files Manager, com.android.documentsui I get the same error.
Now, I'm wanting to know what specifically is borked about just the VLC packages? Does anyone else get this problem? Why is that pm install ./appname.apk in the shell works, but the GUI doesn't?
I am using the ARMv7 builds, but specifically had failure with 3.0.11 -- it's been failing and giving me problems since at least 3.0.9.
I'm using LineageOS 14.1-20180616, based on Android 7.1.2.
