The application fails to open, or can't access a directory?

The quickest thing to do is to run the application in question from the terminal with the immediate error as to why it isn't launching.

So, for Krita just enter krita in Konsole. The error should be immediate and probably short.

OnlyOffice (installer from website+snap)

So both the snap nor either the deb or appimage on their website do not open? OO do not have an "installer"

What does this mean, exactly?
Is flatpak fully set up? Enabled, then adding flathub, *possibly* a reboot,( though I have never had to despite messaging)?

Any errorrs?

As a caution, make sure that your partiton(s) are not full, though that would affect everything

Every application has something different depending on how much it relies on libraries present in the root folder. For example, steam has:

Code:

bin_steam.sh[5441]: Failed to extract /usr/lib/steam/bootstraplinux_ubuntu12_32.tar.xz, aborting installation.

Krita's got:

Code:

Could not prepare delete temporary resources query. QSqlError("", "", "")

Alongside the GUI errors Could not initialize the resource cache database and The resource location at /home/username/snap/krita/109/.local/share/krita/ is not writable
And OnlyOffice spit out:

Code:

Segmentation fault (core dumped)

(By the way. I'm using their provided .deb file. Though i did just notice they have an appimage version, so that should work for my purposes)
The one thing they all have in common? the output logs are full 'permission denied' and 'cannot be opened' errors. krita and onlyoffice opened their 'startup' screen for 5 seconds before closing. And steam doesn't even have the chance to launch a GUI.

I installed flathub via installing the flathub backend to discover and adding the repo. then restarting when it didn't work (pretty dumb, right?).
The way it 'fails' so to speak is that whenever i try to install a flatpak from the website or load a .flatpakref file. discover hangs. then eventually comes up with an error that says flatpak su returned with error.

closest thing i have to that is an external drive i backed my home partition up to. But it still has 150-200GB left on there. far from the size where it should start causing problems.

Interestingly enough i have noticed some preinstalled apps (Gwenview, Spectacle, KDE Partition Manager) display an error upon startup that usually goes Configuration file "/home/iw/iconfig/appnamerc" not writable. please contact your system administrator so i AM wrong in my assessment about it not affecting preinstalled apps. I guess most of them just don't need external files or dependencies.

What's worrying is this and one of the krita errors tells me that my home folder is being affected too. and considering I'm the owner and have set permissions on that folder to be as free as possible (aware of the security risk but i don't give a rat's) This means it isn't just apps not having root access. it means that the apps are treating the filesystem like a read-only drive. Definitely speculating here but still worrying.

(Funnily enough this may explain why my custom SDDM theme, Sugar Candy, is bugging out on me. Again, just speculating but i would make a lot of sense)

Actually, that is quite unrelated.Your Sugar Candy theme is ancient, and for Plasma 5 - it is incompatible with Plasma 6. You will want a fork that is less than two years old (preferably less), and is stated to work with Plasma 6, and is not lying about it (I have seen a few instances of those on other themes in the past). KDE doesn't control the store where these themes are hosted, and they haven't split out the Plasma 6 compatible stuff like they did with Global Themes.

Either you do not have write permissions, not ownership, or there is something wrong with the file system or drive. If it were permissions, you would have different errors here, like permission denied.

Poke around some directories using ls -la

Code:

$ ls -la ~/.config

I have a feeling it isn't the permissions, Hopefully you see a lot of W's in yours.

Still, check out your drive space, using df -h This specific error is a symptom of a full partition as well as the other causes mentioned.

Code:

$ df -h
