Web-greeter installer fails compiling themes

[thekitsunedev]

Environment

• OS: Arch linux
• web-greeter version: 3.5.3
• LightDM version: 1.32.0

Bug description

Installer fails to build web-greeter when compiling themes due to a deprecated TypeScript compiler option.

themes/themes/gruvbox/tsconfig.json:47:25 - error TS5107: Option 'moduleResolution=node10' is deprecated and will stop functioning in TypeScript 7.0. Specify compilerOption '"ignoreDeprecations": "6.0"' to silence this error.

47     "moduleResolution": "node",                  /* Specify module resolution strategy: 'node' (Node.js) or 'classic' (TypeScript pre-1.6). */
                           ~~~~~~

Steps to reproduce

Either:

yay -S web-greeter

or

git clone --recursive https://github.com/JezerM/web-greeter
cd web-greeter
sudo make install

Temporary fix

git clone https://github.com/JezerM/web-greeter
cd web-greeter

Add "ignoreDeprecations": "6.0" to compilerOptions object in

• themes/themes/gruvbox/tsconfig.json
• themes/themes/dracula/tsconfig.json

Then compile with sudo make install.

I have been having this issue too. The manual fix @thekitsunedev suggested does work but I cannot work out how to get the Aether theme to work with this setup. Any help would be appreciated! 😊

Hi @Jamming17
Could you share what specifically isn't working? I've got it running fine on my end, so I might be able to help you narrow it down once I know a bit more about your issue.

[Jamming17]

Thanks @thekitsunedev

For some more context, I am on Arch Linux and I have been using the lightdm-webkit-2-greeter up to this point with the Aether theme. I realised today that it was abandoned and has been having problems crashing recently, so I was looking to switch. I found this repo and decided to install, had the issue you reported here and now here we are.

I have the web-greeter working using the method you provided and it defaults to the gruvbox theme. I want to switch to the Aether theme with my custom background and colours and stuff I had with the old greeter. I installed the Aether theme for this greeter from this repo, but I did this using the package from the AUR using yay. I then edited the /etc/lightdm/web-greeter.yml file to have "Aether" as the theme.

But when I restart lightdm, I just get the gruvbox theme. I am wondering if this is because I had to install web-greeter manually from GitHub using the method you provided rather than just from the AUR, though I am not great with Arch so I am not sure how installation methods change things behind the scenes.

I hope this is all useful info. Please ask for more information if you need it and I shall provide as soon as I can. Thanks for the help ❤️

@Jamming17 The source of your issue is that in /etc/lightdm/web-greeter.yml, you have set the greeter.theme key to Aether. To fix this, replace the leading capital 'A' with a lowercase 'a':

greeter:
  theme: aether

This should resolve the problem after restarting LightDM. 🥀

@thekitsunedev
I tried what you said but unfortuantely it didn't work, however I have now fixed the issue and have the Aether theme working!
I found the themes that web-greeter uses are stored in the /usr/share/web-greeter/themes directory, and there was no aether located there. So I cloned the aether repository into that directory and now it works.
Now all I need to do is mess with the configuration to get my old greeter back.

Thanks for all your help, I am very grateful 😊

Did anyone else have lightdm completely unable to start on boot?

Wondering if it's related to this issue, but I'm trying to look into it.

Note: works when you use another greeter, like lightdm-gtk-greeter, which I swap to in situations like this.

Update: I highly suspect the orphaned AUR package python-pyqt5-webengine, but need to confirm.

[Jamming17]

@tuurep Yeah got that today, very frustrating. It is something to do with the greeter. For now I have no idea how to fix it and just installed the GTK Greeter too while I wait for the issue to be resolved.

[tuurep]

Thanks for confirming!

I'll give a try at bumping the version of AUR python-pyqt5-webengine, but as I tried installing in a venv and there was some further issue, I doubt that will resolve everything.

Edit: I was mistaken, there was no new version to bump to

[tuurep]

People seem to be gathering around a problem at AUR qt5-webengine, looks related:

https://aur.archlinux.org/packages/qt5-webengine

When I tried to rebuild, took like half an hour and ended with an error :/ makes it reeeaally slow to test what's going on.

Sorry to pollute this issue, opened a proper one: #88
