Kodi 17.0 upgrade doesn’t work.

I am running Linux Mint 18 on my HP Laptop. I was running kodi Jarvis 16.1, this worked fine. Then my update manager posted a list of updates, one of which was Kodi update to 17.0.
This was a total disaster half of my addons didn’t work – when I tried to downgrade back to Jarvis, I had all sorts of errors, with broken files.
So at the moment I have Kodi Isengard from the Mint Synaptic repo, but wan’t to restore to Jarvis.
Can anyone guide me as to how I can upgrade my Kodi 15 Isengard, back to 16.1 Jarvis.
I DON’T WANT ANYTHING TO DO WITH KODI 17 KRYPTON.
