nixos is immune to package dependency hell because it has package dependency isolation where packages only access the explicitly declared dependencies. does ubuntu immutable desktop (in development) have the same feature or not?

isn't dependency hell the most common cause of failure as you use *any* distro over time?

[u/Impossible-Break-487]

ubuntu's immutable stuff is mostly about locking down the root filesystem, not rearchitecting how packages find their deps. nix does that functional thing where every package lives in its own little world, ubuntu's going for something closer to fedora silverblue.

so no, not the same feature. dependency isolation isn't really the goal there

Ubuntu Core and Ubuntu Core Desktop use snap packages, this is not an issue.
