dpkg error with Linux Kernel 5.4.179 Oxnas (OX820) Pogo V3 package (2 replies)

Hey, I'm really happy to see continued development for these awesome little devices. I first learned about this place about 7 years ago and enjoyed setting up a couple of Pogoplugs as network shares. Then life happened and they were eventually boxed up and shelved for a few years.

I dusted one of them off today and it started up as if they were online just yesterday! I ended up needing to update the uBoot because I wanted netconsole and that worked out well as far as I can tell.

Now, I'm trying to update the kernel but I'm stuck at step 4:

Linux Black 4.4.38-oxnas-tld-5 #1 SMP PREEMPT Sun Dec 11 17:32:48 PST 2016 armv6l

Am I missing something obvious here? I feel like I am.
