Package: libglib2.0-0 Version: 2.58.3-2+deb10u2 I upgraded my system (a headless microserver) to buster today using the standard commands (apt-get upgrade and apt-get dist-upgrade) and did not notice any errors causing it to fail.
However my minidlna server (the latest packaged version, 1.2.1+dfsg-1+b1) does not start giving the following error: $ sudo /etc/init.d/minidlna start /usr/sbin/minidlnad: symbol lookup error: /usr/lib/i386-linux-gnu/libgobject-2.0.so.0: undefined symbol: g_variant_dict_ref The same error is given by trying to run ffmpeg. Looking back, the error did appear twice when upgrading the system: Setting up libgtk2.0-0:i386 (2.24.32-3) ... /usr/lib/i386-linux-gnu/libgtk2.0-0/gtk-query-immodules-2.0: symbol lookup error: /usr/lib/i386-linux-gnu/libgobject-2.0.so.0: undefined symbol: g_variant_dict_ref And: Processing triggers for libgdk-pixbuf2.0-0:i386 (2.38.1+dfsg-1) ... /usr/lib/i386-linux-gnu/gdk-pixbuf-2.0/gdk-pixbuf-query-loaders: symbol lookup error: /usr/lib/i386-linux-gnu/libgobject-2.0.so.0: undefined symbol: g_variant_dict_ref Searching for advice I found bug reports (894763, 896019) related to a different symbol error for the same library, with the discussion based on older versions not being deleted. Although the symlink was to the newer file, there was an older version (libgobject-2.0.so.0.3600.4) so I deleted this. As that did not make any difference I moved the file and symlinks and reinstalled the libglib2.0-0 package. However this did not fix the problem but also showed the error. $ sudo apt-get --reinstall install libglib2.0-0 Reading package lists... Done Building dependency tree Reading state information...
