I just upgraded from Ubuntu GNOME 16.04 to 16.10, then I cannot run
Output of that command is:
Traceback (most recent call last): File "/usr/bin/software-properties-gtk", line 37, in <module> from softwareproperties.gtk.SoftwarePropertiesGtk import SoftwarePropertiesGtk File "/usr/lib/python3/dist-packages/softwareproperties/gtk/SoftwarePropertiesGtk.py", line 34, in <module> from aptdaemon import client File "/usr/lib/python3/dist-packages/aptdaemon/client.py", line 43, in <module> import defer ImportError: No module named 'defer'
This means that all other programs relying on
aptd are throwing errors.
I have tried reinstalling the package
python-defer which proceeded without any errors but that did not correct this problem.
Any suggestions what went wrong? Thanks!
