Getting 2 different version from APT repository

I have a desktop and raspberry pi both running ubuntu. The desktop has an x86 chip and the pi has an arm chip.

I’ve installed syncthing on both of them but the version for the desktop is 0.11.26 and the version I’m getting on the pi is 0.12.4 and they won’t talk to each other.

I realize I could manually install syncthing on my desktop but I want the updates to be managed through apt.

Anyone know why the versions are different, or what I could do?

apt-get update

Oh I figured it out, I forgot to add the correct release channel to my apt sources list. Don’t know where I was getting it from before
