So some info:
Phone - Samsung Galaxy On5 (T-Mobile)
Computer OS: Arch Linux
SuperSu file used - http://download.chainfire.eu/supersu-stable
TWRP Image used - https://twrp.me/devices/samsunggalaxyon5tmobile.html
Flashing Utility used - Heimdall
So I downloaded both the SuperSu file and the TWRP Image.
Stored the SS file on my sdcard.
Enabled usb debugging.
Used adb to reset my phone into Download Mode.
Then used 'sudo heimdall -detect' to verify that it is visible.
Then used 'sudo heimdall flash --RECOVERY twrp-3.0.2-0-on5ltetmo.img'.
[quantum@quantum Downloads]$ sudo heimdall flash --RECOVERY twrp-3.0.2-0-on5ltetmo.img
Heimdall v1.4.1

It seemed to work. I rebooted my phone and held the home button power button and volume up button to boot in recovery mode.
First I get this 'Insalling system update...'
For about 15 secs
Next I get this screen 'No command...'
For about 2 secs
Then I get this screen
I did both "Apply update from ADB" (by sideloading the ss file) and "Apply update from SD card" and I get the same message:
Finding update package ...

E:failed to verify whole-file signature
E:signature verification failed

No idea what to do from here.
Help please.
