I don't think so, because I don't know what permission(s) is lacking. I couldn't finish the terminal command without knowing what the problem is. I reiterate that everything was fine until the Vanced Manager updated, and now it won't update the corresponding apps. Only thing I can think of is that you have to go to system settings and manually set the Manager to allow installation of unknown apps, which I did long before the Manager updated. I've uninstalled and repeated the same process, with no luck. It's just very strange to me that this is the only device that I'm having this issue with. I do appreciate the response and the time you took to try to help me resolve it, but my other device with LOS 17.1 asks for no permission other than to allow the installation from unknown apps. There's a bug somewhere with the ROM, or more likely the application for this ROM. Thanks again for the response.
