An error was detected in the current theme

Following a guide from here: https://youtu.be/oQ8RWtD3MTQ?t=1031
I was attempting to install the lightdm-webkit2-theme-glorious but encounter the error:
An error was detected in the current theme that could interfere with the system login process ... similar to looking like this:

Looking over https://github.com/manilarome/lightdm-webkit2-theme-glorious and seeing the mention of the race condition, I attempted to enable debug mode, upon reboot I still get the dialog and am not able to right click until I select "Load Default Theme" (I also seem to have to make the same selection multiple times before it will allow me to continue on) after selecting "Load Default Theme" I'm able to right click and choose "reload" but it's still not the glorious theme.

but it's still not the glorious theme.

What do you mean by this? Even if there's an error it should already be the glorious theme.

Wow Linux Scoop used my theme in their video? Damn lol. Anyway, Linux Scoop uses an old installation method. The webkit_theme should now be glorious instead of lightdm-webkit2-theme-glorious. So yeah. You should read this part of the README. Closing this now! Thanks for reporting!

Well, I don't know if it's the glorious theme, cause I can't actually use it because of the error dialog box, that forces me to use the default theme instead. Also, it doesn't look anything like the video.

It may be an old installation method, but the video was uploaded only a few weeks ago and it seemed to be working for them.

The webkit_theme should now be glorious instead of lightdm-webkit2-theme-glorious.

What do you mean by this? Like the package name, the reference in the config file? Because if you mean in the config file that was what was set just as it was in the video. And per your...

So yeah. You should read this part of the README.

It says... and I quote:

"$ yay -Syu lightdm-webkit2-theme-glorious"

not "glorious"

You can press cancel to see the current broken theme. If it's black screen then lightdm can't detect the theme you set.

Yes the package name is lightdm-webkit2-theme-glorious but the theme name is glorious.

I watched it and they set the webkit_theme to lightdm-webkit2-theme-glorious. Again, it should be glorious. (Believe in me, i'm the dev lol).

The version that they've used is v1.0.X, while the version in this repo is already v2.0.x.

Do you have a time stamp link of where in the video?

There is only one "glorious" package in the AUR and it's the one I have installed.

Maybe this will help, this is what I have set and configured on my system... show me where I'm doing wrong....

Here is what I get on a fresh reboot...

Here is what I get when I press [esc]

It's not needed. I got mixed up lightdm-webkit2-greeter.conf and lightdm.conf. Pardon my ignorance earlier. Linux Scoop indeed set webkit_theme to glorious in lightdm-webkit2-greeter.conf.

Here is what I get when I press [esc]

Please, press the cancel button because escape defaults to Load default theme, iirc.

Anyway you can debug it by running lightdm-webkit2-greeter in your terminal.

Pressing cancel does nothing for me, the dialog remains. (Although I think I remember pressing cancel multiple times after getting to default theme and it finally going away) And pressing escape defaults to "Fall back theme" for me.

Anyway you can debug it by running lightdm-webkit2-greeter in your terminal.

I'll test this and see what I come up with.

[CyberManifest]

Now we're getting somewhere...

[eromatiya]

Now I know what's causing the problem. It's the Credits file in your backgrounds directory. Try to delete, like rm it to oblivion lol. Lightdm webkit2 has a limitation, it cannot detect if the file format/extension that's why it cannot exclude it. Hence the "error opening directory" error. It's already in the README. But yeah, it is something that can be easily overlooked.

Yeah, I removed them, I'm also uninstalling the mint backgrounds from the AUR just to be double safe. Testing now... Thank You ;-)

[CyberManifest]

Update, I can confirm, removing the unknown file formats seems to have resolved the dialog box issue. But now what to do with these...

[eromatiya]

Those are just a bunch of logs. Don't worry about them. Try to login again, it should work now without a problem.

Great, Works fine now! Thank You...
Marking this issue resolved and closed.

P.S. Final Product:

[surfaceflinger]

If someone else has this error and there is no output in logs:
chmod -R 755 /usr/share/lightdm-webkit/themes/glorious
I wasted 1 hour "fixing" because I messed up permissions during installation 😊

I tried everything in here and nothing works :(

Hello @manilarome, I'm having the same issue but my log for lightdm-webkit2-greeter is different. Please take a look.

[Cheeseboy8020]

I have same issue

[zackyvt]

I have same issue

I'm having the exact same logs

Is there a fix?

[meisme-dev]

Reinstalling it using yay -S lightdm-webkit2-theme-glorious --overwrite "*" fixed it for me.

[ronylee11]

hi, how can i disable the error popup entirely? the theme works great for me, just gets kinda annoying having to press cancel everytime i reboot
debugging with lightdm-webkit2-greeter does not have that popup tho
tried searching in
/usr/share/backgrounds/
/usr/share/pixmaps/
but i only find files with .svg, .png, and .jpg extensions, can u specify the exact path for the Credits file? ( cant recall if i removed it months ago)
i also removed
/usr/share/licenses/lightdm-webkit2-theme-glorious/LICENSE
/usr/share/lightdm-webkit/themes/glorious/LICENSE
but the annoying popup still occurs

[nkahne]

I get similar errors. Something seems to be up with the vars.js file?
I have only picture-like files in usr/share/backgrounds, so that can't be it.
