Debian 13:

$ uname -r
6.12.88+deb13-amd64

$ snap debug sandbox-features|grep confinement
confinement-options:  classic devmode

$ snap debug confinement
partial

$ aa-enabled
Yes

Ubuntu (24.04):

$ uname -r
6.8.0-117-generic

$ snap debug sandbox-features|grep confinement
confinement-options:  classic devmode strict

$ snap debug confinement
strict

$ aa-enabled
Yes

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?

    Companies are more likely to use Ubuntu instead of plain Debian or another Debian-based distro on their workstations. No one in this chain aims to bring snap packages to other distros and ensure that they work properly there.
