@Lakotaubp I did, yes. the cable and usb port is the same as i have used many times before with that phone, and has worked fine, so i dont believe that is the problem. the device has stock android on it atm.

@Edward-Wilhelm I installed it from the debian package, i will try the snap package.

@Emphrath Which i did, as shown in the terminal in the background of the screenshot.

I decided to try ubports on my old nexus 4 yesterday, so downloaded the latest installer, checked my computer could see my nexus 4 both with adb and fastboot, fired up the installer it started that download as shown in the screenshot as it was taking a while i went to bed, got up around 7 hours later and it was stuck in the same place, can anyone advise please as to where the possible issue is please and what is going on.
