Could not open library 'glib-2.0.so.0': glib-2.0.so.0: cannot open shared object file: No such file or directory.
Could not open library 'libglib-2.0.so.0': libglib-2.0.so.0: cannot open shared object file: No such file or directory

I also opened a PR to fix the template so this will be done automatically.
I’m only posting this post so someone searching for any keyword in it will find it.
