No such file or directory killall?

Error changing wallpaper: [Errno 2] No such file or directory: 'killall'

this shows every time i try to change the wallpaper with SWW backend(haven't treid others) currently on nixos and i got the package from the nixos unstable channel.

Hmm, interesting. But, killall command exists in NixOS, right?

Does the output also say something like this?

Selected image path: .somefile.jpg
Wallpaper was set with swww

Also, this error kills the program, or it just outputs into the terminal and nothing happens?

I suppose I know how to bypass this problem, but would be interesting to find out the cause.

EDIT: I looked around, it seems that on NixOS you need to include even these small utilities in your build, here is some info.

I pushed a quick fix to PyPi and to Github, so AUR and pipx versions should work. But I don't know who maintains the NixOS package, hopefully it will be updated soon too. Anyway, you just need to include killall in your path or something like this (it is usually available by default, but NixOS is a bit special).

Just output in the terminal

Already added the killall to global pkgs until someone fixes it

But know im getting

even having the swww backend on the gui tho when i try via terminal it kinda works

Some errors are normal to have, like "There seems to already be...", but your first screenshot is puzzling. I'll try to reproduce it tomorrow, but I think it is related to your first bug report and is likely already fixed with version 1.9.2.

As a quick fix you can try to also install swaybg :D

Basically, what happens is that normally, before using swww program tries to kill swaybg because they don't play nicely together. My mistake was that I didn't put into try-except as I didn't imagine there could be a case when this can fail. Anyway, thank you for reporting!

will try it, tysm for the response

[anufrievroman]

I'll assume that this issue has been resolved

@anufrievroman Is this behavior planned to be changed? While installing swaybg indeed fixes the issue, I personally don't want to install the tool I won't ever use

Do you mean that you see the errors in the terminal? I mean, it is sort of normal behavior because it's GUI app, so I assumed the only time you'd see these errors is when you run it from the terminal for debugging, that's why it is quite generous with errors, but it isn't really an error, just information what it tried to do. So swaybg is not required at all. Or I don't understand the problem correctly?

I try to run the application with waypaper command in the terminal. The app runs, but as soon as I try to change the background image, I get the above error No such file or directory: swaybg, and the bg image isn't changes. Only if I install the swaybg the error is gone and the background image changes.
