Hi Oier, Apologies, I misintrepreted the output of the command from #6. The U in front of the function names actually means they're undefined. I dug a bit deeper and looks like the function in question is actually in libgirepository. So here are a few more things you could try:
- Run this command to see whether the function is defined in that file: nm -D /usr/lib/libgirepository-1.0.so.1 |grep g_vfunc You should get something like this somewhere in your output: 0000000000012b50 T g_vfunc_info_invoke - Check whether _gi.so is linked against libgirepository and can find it, running: ldd /usr/lib/pyshared/python2.7/gi/_gi.so Somewhere in your output you should see something like this (it's OK if the paths are slightly different, we're trying to check whether libraries are correctly linked, but please post if you see any "Not found" messages or similar errors): libgirepository-1.0.so.1 => /usr/lib/libgirepository-1.0.so.1 libgobject-2.0.so.0 => /usr/lib/x86_64-linux-gnu/libgobject-2.0.so.0 libgmodule-2.0.so.0 => /usr/lib/x86_64-linux-gnu/libgmodule-2.0.so.0 - run the ldconfig command to reconfigure the dynamic linker bindings: sudo ldconfig You could pipe the output to a file and afterwards confirm that there are no "not found" messages or other errors for any of the linked libraries. - Run the debsums check on libgirepository-1.0-1, see if any of the files are missing/damaged. - Reinstall libgirepository-1.0-1 as done on comment #5 for python- gobject. Hopefully at least one of these will shed some light on the problem.
