For reference, I'm running kubuntu 26.04.

So I made another post asking how to disable plasma updates, but I think I may be misunderstanding something, and I want to see what, if any, of my prior knowledge/assumptions are incorrect. I have some things I want to have help clarifying, and I would greatly appreciate any help.

Questions:

1- Will running \`sudo apt-get update && sudo apt-get -y upgrade\` update my plasma version, and in what way. Using semantic versioning X is a major update, Y is a minor update, and Z is a patch/bugfix (X.Y.Z) Would it upgrade all 3, would it only update Y & Z, or would it only update Z?

2- what does the backport repo do, and how does it differ from.. idk I guess the 'normal' repo? Also what would be considered the "normal" repo.

3- do Y & Z updates change UI elements. And if so, do Z updates also modify UI elements? If so, is there a way to only get security and bug fixes without having any UI updates/changes?

4- will the "update all" button in discover update my plasma version in a way that would change my UI?

5- based on the above questions, is there anything else you think I might not be understanding? And additionally, is there somewhere that I could RTFM? I've found some stuff detailing \*how\* to update, and what changes were made in specific version updates, but I haven't found anything that meaningfully/adequately answers my questions.

Like the title says, I would like to ensure that the desktop environment cannot update.

I would like to be able to update all the other packages (either via apt-get update/upgrade or via the discover store) as usual. My main concern is that I have a lot of system files modified that aren't designed to be modified, and I don't want to risk certain system files being updated to a pre-compiled version. I want to make sure that plasma cannot auto update, and that I cannot update plasma by accident.

I'm using kubuntu 26.04

Edit: I'm well aware of holding apt packages. I was hoping there was some way to ensure that plasma can't update to 6.7, 6.8, 6.9(nice), etc. unfortunately it's looking like this isn't possible without holding back a bunch of packages which I'm already aware is a bad idea (specifically holding back system packages)
