What does this mean, you ask? Well, basically every Snap package you thought was running isolated in it’s own little sandbox were running unconfined the whole time. The prorpietary app you removed the :home connection from, so it wouldn’t be able to access your home directory? Well, it could have exfiltrated all our private files in the meantime.
How is this not a bigger deal and how are Snaps ever to become mainstream when even today, more than 10 years after the introduction of snaps, you can’t run them sandboxed on a huge portion of Linux distros?
Hardly anyone but Ubuntu users use snap, because snap was created by Ubuntu, and their efforts to get other distros to adopt it never gained traction. Debian users are especially uninterested in using snap, and some people on Debian are ex-Ubuntu users who switched because they didn’t like snap.
Yeah, that tracks - I came back to Debian after a few years on Ubuntu, and even before I returned, I removed snap from my Ubuntu system.
It’s not a big deal because the answer to the problem is “don’t run snaps”.
Thank the gods. Nobody wants that proprietary walled garden in Debian.
It’s just a tool for Ubuntu to control, and maybe even sell itself one day to Goog’s or MS or similar.
Don’t want it in Debian.
It’s not proprietary, though.
I mean I get the concern but I’d be surprised if even 1% of Debian users had any interest in running snaps
Snaps is something you drink.
AFAIK only users who have it shoved down their throat by Ubuntu use snap packages.
Because snaps is a Ubuntu thing, and not particularly widely used on Debian.

I actually don’t understand what use case snapd on Debian covers better than docker on Debian or snapd on ubuntu
Who TF cares? If you want containerized apps, run Flatpak. There is no application packaged for Snap that I’ve not seen packaged for Flatpak, too. And Flatpak is better in basically every way.
Except malware. No one repackaged the snap malware for flatpak 😭
have you actually looked at a snap’s status?
