Ok, I understand what you meant, thanks.

Basically, after I’ve read all of that, it’s clear as day that security is not a priority on Testing. And while band-aid solutions do exist, it’s simply not designed to be secure.

Yeah, I wouldn’t run it in a production environment.

Sure, but even in those “few cases” Testing will get them soon.

I did read at some point that Testing may receive security updates later than stable, might be in those cases in which backports come straight from unstable.

I don’t recommend going for (Debian’s/Devuan’s) testing (branch) as it targets a peculiar niche that I fail to understand; e.g. it doesn’t receive the security backports like Stable does nor does it receive them as soon as Unstable/Sid does. Unstable/Sid could work, but I would definitely setup (GRUB-)Btrfs + Timeshift/Snapper to retain my sanity.

From https://backports.debian.org/ :

Backports are packages taken from the next Debian release (called “testing”), adjusted and recompiled for usage on Debian stable

So by definition, security backports in stable are present in Testing in the form of regular packages, right?

I remember having some issue like that, but I’m not sure if this was the fix.

Try unchecking “Show desktop notifications when the song changes” on Spotify’s settings (right now it’s under the Display section).

Makes sense, thanks.

New to Linux: in which case would you stick with an “old-old-stable” release?

Software incompatibility?
