I think that's an artifact from running just the liveimage and not installing it fully to the VM. I'm 99% certain Ark is included in a default Cachy/KDE install.
Anyhow.. "You can open a terminal and type".. yeah, no. This is exactly what I or any other Windows/desktop user does not want to be doing on a desktop computer. Linux always promised to get rid of this "just use terminal bro", which is what being a desktop OS is all about, but it never got there..it seems.
The premise of my test was to see whether the OS is ready out of the box(the main point of a linux distribution, after all). But neither was. Again, I am not saying it is not usable. I am just saying it requires more work to be put into it from the get-go than I am willing to put in, despite having the skill and knowledge to do so.
Then stay on windows. You'll have the same issues with MacOS from time to time.
If you're willing to learn things you have plenty of options. If not? You'll be limited. Tradeoffs.
