@Jihun-Kim-kmu Hi, have you solve this problem? I also encounter 'GLib' error, and I don't know how to run the code normally.

Hi @ChunmianLin I solved problem with this code in my case

dpkg --force-depends --purge fontconfig-config

aptitude install fontconfig-config

dpkg-reconfigure fontconfig-config

[linchunmian]

Thanks. But I wonder the error information occured in my project is not the same totally as that in your code. Actually, in my case, there is not 'failed to read config file' problem, but the 'GLib-CRITICAL....segmentation fault(core dumped)' error are reported as the same as you present. I am so confused what cause this problem. Anyway, many thanks for your value help.

maybe I encounter same error haha..... Are you solved this problem? (python:22692): GLib-GObject-WARNING **: 19:13:46.651: cannot register existing type 'GdkDisplayManager'

Yes, it is. But I still don't solve the bug. I don't know why this problem cause.

[Gironote]

I solved problem with $ sudo apt install libcanberra-gtk-module libcanberra-gtk3-module

[linchunmian]

Thanks for your kind suggestion. But it seems no effect for my code. I installed these two packages, but it still presents the same error.
