I recently ran into the same issue. libglib-2.0-0 was upgraded on my sid system. The current version is libglib2.0–0/unstable,now 2.58.1–2 amd64 During the next boot, I was unable to start lightdm. The error was Dec 03 14:32:38 host lightdm[4829]: /usr/sbin/lightdm: symbol lookup error: /usr/lib/x86_64-linux-gnu/libgobject-2.0.so.0: undefined symbol: g_date_copy I followed the discussion in this thread, and checked these files: my /lib/x86_64-linux-gnu/libglib-2.0.so.0 was a symlink to /lib/x86_64-linux-gnu/libglib-2.0.so.0.4800.1 my /usr/lib/x86_64-linux-gnu/libglib-2.0.so.0 was a symlink to /usr/lib/x86_64-linux-gnu/libglib-2.0.so.0.5800.1 Now that GLib puts these files under /usr/lib/x86_64-linux-gnu/, my /lib/x86_64-linux-gnu/libglib-2.0.so.* files from an old version of glib should certainly have been deleted during the installation of the new version, but somehow this didn't happen. I suppose one way to reproduce this bug is to install the system with libglib2.0–0 around version 2.48 and then do an upgrade to the latest version.
