unsnap VS nix-bubblewrap

Might I suggest unsnap?

This seems very similar to Alan Pope's unsnap project - Is there anything you're doing differently? https://github.com/popey/unsnap

If you are referring to this project, then I'm sorry to tell you that you got it wrong.

Reminder that if you don't like snaps, it's pretty easy to migrate away using: https://github.com/popey/unsnap

Might check out https://github.com/popey/unsnap

You can just use this to remove snap tho: https://github.com/popey/unsnap

How? Should I follow these instructions? https://github.com/popey/unsnap

The best Debian/Ubuntu-based distro that uses Plasma would probably be Kubuntu with unsnap if you're not a snap fan.

If snaps are your only issue, don't leave Ubuntu. Look into unsnap (https://github.com/popey/unsnap). Determine if your lag is snap related.

Snaps are so bad that one of Canonical's star employees left and tweeted about snap issues saying that "They get ignored or dismissed. The CTO flat doesn't believe there's a problem. The team is understanffed and there is no motivation from IoT and enterprise focused people to fix desktop problems. Been trying from the inside for years. I gave up hope and left.". Same guy later went on to create the unsnap repo on github which helps users find replacements for their snap packages among flatpaks etc - and this wasn't a "jaded employee" thing so much as him trying to look out for users' best interests. Good on him.

Looking things up, someone has linked the Flatpak containerisation tech (bubblewrap) into the Nix store: https://github.com/fgaz/nix-bubblewrap

It looks... somewhat abandoned, but I'd wager it still works today. Failing that, setting up a shell alias to launch a regular binary in bubblewrap isn't too hard either.
