Update Issue

Just pick up a Vero 4k I am a noob to OSMC and Kodi.
When I tried updating because it was showing I was on July software 17.3 I think,it said no updates available so I came online and downloaded the newest one and put on a usb and now am on the October 17.5 Kodi.

I then updated again and it had some packages like arm64 etc Debain etc it downloads all this and says updating cache please wait.
After this box disappears nothing happens so I check updates again and it just downloads all these packages again.
what do I need to do to make these packages install properly.

This sounds strange and you should not have needed to do update via USB.
Upload logs via MyOSMC and share the URL so that we can help
