Accidentally screwed flatpak up through override commands, how do I fix?
-
Try “flatpak override —user —reset” and “flatpak override —system —reset”.

Linux causal here.
Long story short: I've been trying to fiddle with scaling on Kubuntu 24.04 after fixing a broken install, all the flatpak apps suddenly got stuck on x11 mode and refused to use anything else and wouldn't scale at all, tried following some guides online and everything got screwed up, nothing will launch anymore.
I used
sudo flatpak override --system
followed by some other stuff, no idea if that was a major mistake or not but that's what the search results recommended.Tried reinstalling flatpak, tried reinstalling an app to see if that fixed anything (it didn't), tried to reverse the overrides through other commands (didn't do anything), took a peek at some folders to see if I could delete some configs or something and reset flatpaks settings (couldn't find anything), and a bunch of other stuff, literally nothing works man, no idea what's going on... System apps launch fine, deb apps too, so the system is fine I think, scaling on system apps works, but flatpak and it's apps is completely screwed, won't scale, and now just won't launch whatsoever, help?
man 1 flatpak-override
Overrides the application specified runtime requirements. This can be
used to grant a sandboxed application more or less resources than it
requested.By default the application gets access to the resources it requested
when it is started. But the user can override it on a particular
instance by specifying extra arguments to flatpak run, or every time
by using flatpak override.The application overrides are saved in text files residing in
$XDG_DATA_HOME/flatpak/overrides in user mode.Scroll down, you will see the
--reset
option to remove the overrides.I noticed you used
sudo
to run the command, so I think the override files are stored in/var/lib/flatpak/overrides/
. To get everything back to normal, try deleting everything inside that directory.If you want to override the system-wide settings, you can create files in the same format as the ones in
/var/lib/flatpak/overrides/
, but put them in/home/your_username/.local/share/flatpak/overrides/
.To generate the pre-config settings for a flatpak, you can use the
flatpak -m info app_id
command. This will show you some info about the flatpak, and the-m
option will print out the metadata. You can also save this info to a file by runningflatpak -m info app_id > ~/.local/share/flatpak/overrides/app_id
.When you edit the file, pay attention to the
Context
,System Bus Policy
, andSession Bus Policy
sections and delete everything else. By default, flatpak is set to share some resources, but you can deny access by adding an exclamation mark before the resource, for example, you could changeshared=network
toshared=!network
.If you're looking for a user-friendly way to manage flatpak permissions, I recommend checking out
flatseal
. It's a great GUI tool that can make it easier for you in this case.That being said, it's always a good idea to be cautious when using commands posted online. Make sure you understand what you're doing before copying and pasting anything into your terminal. And if you're ever unsure about something, there are some great resources available to help you out.
One of the best places to start is the Arch wiki, and I think,

man
is a friend everybody needs!That's definitely handy, gonna bookmark that stuff somewhere for later on, thx! Though I'm not the best with technical stuff or big ol' manuals, and right now I sorta don't have the time or energy to sift through all of it, just wanna fix this issue real quick if possible so I can continue with my day.
I did check the var lib override folder, nothings there strangely, no hidden files or anything even, completely blank. Scrolled down with the man 1 command in the terminal, also nothings there, what am I looking out for here? Are the overrides gone? Is this a different issues now or? Said something about X server missing when running an app through the terminal, what do I do about that?

It's likely because it can't access X11 or Wayland. To fix this, try editing the files in
/home/your_username/.local/share/flatpak/overrides/
like I mentioned earlier. Specifically, look for thesockets
line and make sure it includeswayland
,x11
, andx11-fallback
likesockets=wayland;x11;x11-fallback;
. This should help you launch flatpaks that need X11 access. -

If you are looking to mess with what your flatpaks can do, Flatseal it is really nice for managing permissions, for your flatpaks.
It may not be what you are looking for, but though I would drop it in just in case.

Problem is that it wouldn’t launch for them. Fedora has an RPM for it, but I don’t think Ubuntu does.

Alright I took a look, and all I see are text files of only a few of the apps, nothing else is present as far as I'm seeing right now, and in them there's only a single command of text, all of them are different. Is that normal?
Yes, they are different because they are for different flatpak applications.
What's in the files? Do they have a line called
sockets
? Is that line set tox11
orx11-fallback
? Have you tried adding those options likesockets=wayland;x11;x11-fallback
? I usually get an error saying I can't connect to the display or that X is missing when I revoke access tox11
orwayland
. Or did you remove thex11
from your system? -

. Or did you remove thex11
from your system?Like I said there's literally nothing in the text files but a single line of text, each application only has one and it's different for each. Some have filesystems=host-etc;host-os, some have something else, and again there's only a few applications here, not everything, and the selection is also very random, some of these are applications I haven't used in a while, really weird.
Tried that yeah, didn't do anything at all. X11 is definitely installed, I checked, and all the flatpaks only ran in x11 mode before all of this regardless of what settings I changed through flatseal or command line, so no idea what's going on then. Did I bork flatpak somehow?

True, but I was suggesting Flatseal, more for once the issue was resolved.
