I highly discourage anyone to use Ubuntu Core as part of their solution.

I like Ubuntu, and looked into using Ubuntu Core for an IoT architecture a few years ago - but the "brand store", which IIRC is mandatory for private deployments, are complete madness.

Plus, while the concept behind Snaps is interesting, in practice they seem to be nearly universally reviled.

Completely unrelated but the exactness of this turn of phrase here delighted me so much and without your permission I’d like to steal it for my own use in my daily conversations (without credit).

It's an adaptation of Doofenshmirtz's line from Phineas and Ferb:

It looks like Ubuntu Core lets you disable automatic updates for snaps: https://ubuntu.com/core/docs/refresh-control.

That is really ridiculous. I'm sure some companies out there will pay it without blinking, but how are the little people supposed to evaluate things, heck a former boss at a Fortune 500 I know for a fact will say no thank you, and move on. I would just use DEB packages and setup a package repository myself, what does snap bring that regular debian packaging does not?

We are talking about IoT devices where (hopefully) the company knows exactly what is installed and what not, so I don't think it is a big issue. There may still be conflicts to solve, but you can manage them when you prepare the deb package, not when you install it

Installation Step 1: An Ubuntu SSO account is required to create the first user on an Ubuntu Core installation. Yeah... no.

Is Ubuntu Core closed source? If not, can't someone fork it and remove this requirement?

Been a huge fanboy since Warthog, but as of 20.04 I've sought refuge elsewhere. Turns out, Ubuntu isn't nearly as user friendly as it was back then, in fact, it's one of the least user friendly distros these days! Everybody progressed and you deserve t check it out yourself!

What’s your new distro of choice?

Not the one you're replying to, but started my Linux experience with Ubuntu 6.10, was using it all the way up to ~17, and started using Arch Linux after that since during my time of using Ubuntu, I learnt enough Linux that I could setup my own system (and of course, with the help of the awesome Arch Wiki).

I completely sprinting away with anything canonical. SUSE/openSUSE/Micro RHEL/Fedora/CoreOS nothing else...no more canonical, too many disappointments and trickery into pay massive at the end of the day.

What is Micro RHEL?

Or the ability to make your own snap store.

Buying a Brand Store is also the only official way to have full control of snap updates. Someone at Canonical must have been taking notes from Microsoft -- take away control from users and sell it back in an "enterprise edition".
