Demora cerca de dois dias que o Atualizador de Software não me alerta para atualizações. Esta manhã eu descobri que software-properties-gtk falha repetidamente na inicialização do sistema e se eu tentar iniciá-lo pelo terminal, ele acaba com o seguinte traceback:
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 54, in <module>
from UbuntuDrivers import detect

system_architecture = apt.apt_pkg.get_architectures()[0]
AttributeError: module 'apt' has no attribute 'apt_pkg'
Comportamento semelhante para o update-manager :
Traceback (most recent call last):
File "/usr/bin/update-manager", line 38, in <module>
from UpdateManager.UpdateManager import UpdateManager
File "/usr/lib/python3/dist-packages/UpdateManager/UpdateManager.py", line 58, in <module>
from .UpdatesAvailable import UpdatesAvailable
File "/usr/lib/python3/dist-packages/UpdateManager/UpdatesAvailable.py", line 61, in <module>
from DistUpgrade.DistUpgradeCache import NotEnoughFreeSpaceError
File "/usr/lib/python3/dist-packages/DistUpgrade/DistUpgradeCache.py", line 109, in <module>
class MyCache(apt.Cache):
AttributeError: module 'apt' has no attribute 'Cache'
Portanto, o problema parece estar relacionado aos módulos python apt . No entanto, com Python 2.7.12 ou Python 3.5.2 iniciado a partir do terminal, posso executar esses comandos sem nenhum problema, por exemplo:
>>> import apt
>>> apt.apt_pkg.get_architectures()[0]
'amd64'
Eu também tentei reinstalar vários pacotes de linux relacionados a apt / python junto com software-properties-gtk e update-manager . No entanto, sem sorte.
A lista de (talvez) todos os pacotes que eu reinstalei:
apt apt-utils aptdaemon aptdaemon-data update-manager update-manager-core software-properties-gtk dbus python-pkg-resources python3-pkg-resources python-apt python3-apt python-aptdaemon python3-aptdaemon python-apt-common python-aptdaemon.gtk3widgets python3-aptdaemon.gtk3widgets python3-aptdaemon.pkcompat libapt-inst2.0 libapt-pkg5.0
Felizmente o problema afeta apenas as interfaces gráficas, ie eu posso atualizar, instalar ou remover pacotes do ubuntu do terminal através de apt , apt-get , aptitude , ... Enfim, é um pouco chato.
Atualização:
Eu também tentei (sem sorte) reinstalar todos os pacotes python3 instalados anteriormente:

Eu tive o mesmo problema. Estava relacionado à instalação do pacote ROS python3-ros-buildfarm para testes de pré-lançamento. Ele instala um arquivo /usr/bin/apt.py , que eu presumo está causando este conflito de nomes. Remover este pacote resolveu o problema para mim.
