I'm rather new to Ubuntu and I'm trying to run update-manager on Ubuntu 13.10. I get:
jacopo@jacopo-laptop:~$ update-manager Traceback (most recent call last): File "/usr/bin/update-manager", line 28, in <module> from gi.repository import Gtk File "/usr/lib/python3/dist-packages/gi/__init__.py", line 27, in <module> from ._gi import _APIImportError: No module named 'gi._gi'Error in sys.excepthook:Traceback (most recent call last): File "/usr/lib/python3/dist-packages/apport_python_hook.py", line 64, in apport_excepthook from apport.fileutils import likely_packaged, get_recent_crashes File "/usr/lib/python3/dist-packages/apport/__init__.py", line 5, in <module> from apport.report import Report File "/usr/lib/python3/dist-packages/apport/report.py", line 30, in <module>import apport.fileutils File "/usr/lib/python3/dist-packages/apport/fileutils.py", line 23, in <module> from apport.packaging_impl import impl as packaging File "/usr/lib/python3/dist-packages/apport/packaging_impl.py", line 20, in <module>import aptFile "/usr/lib/python3/dist-packages/apt/__init__.py", line 21, in <module>import apt_pkgImportError: No module named 'apt_pkg'Original exception was:Traceback (most recent call last):File "/usr/bin/update-manager", line 28, in <module>from gi.repository import GtkFile "/usr/lib/python3/dist-packages/gi/__init__.py", line 27, in <module>from ._gi import _APIImportError: No module named 'gi._gi'As far as I have understood, this is a problem related to the fact that I should have python3.4 installed. I installed it in /usr/local/lib, but I always get the same error. In this way I can't even upgrade to Ubuntu 14.04.
