I have installed op25 but I get a no attribute “get gain names” error… I was I guess completely unaware that op25 doesn’t have a gui. What programs can decode p25 phase 2 that can run on a raspberry pi 3 that have a easy to navigate gui? Thank you! Please help

Not many applications will run properly on a RPI3 and decode p25 phase2. If you need a fancy GUI perhaps you should consider obtaining some beefier hardware and looking at SDRTrunk. If you want to continue with the RPI3 you'll find that op25 will do a more than acceptable job of receiving any P25 system using just a single RTL dongle.
The error you are seeing is caused by op25 not being able to connect to the SDR (RTL) device. There are many possibilities, but the most likely is either the dongle is not properly plugged in, or the kernel blacklisting didn't work. Have you rebooted since compiling and installing the op25 sources using the install.sh script? Assuming you did all this, open a terminal and run the "lsusb" command and look for a "Realtek" device. Also look at the /etc/modprobe.d directory for the existence of the file "blacklist-rtl.conf". After that report back with screenshots of the logs etc.
