I just installed the version of Pidora today from raspberrypi.org, I believe it was Pidora 20 R3. I'm trying to get JNOS up and running on the OS and it installs fine but when I try and open the program, the logs throw an error "unable to open /dev/net/tun". When I try to figure out why, it looks like /dev/net doesn't even exist in this version. I tried updating to a newer kernel from https://www.dropbox.com/sh/j4m16akm7dev7c6/AbzVVFacDY and when I follow the instructions to untar the file, I get the error "xz: (stdin): File format not recognized".
Can someone help me figure out where I can get the tun module for 20R3?
