For some reason the update-manager in Ubuntu 14.04 started to crash some weeks ago, and I'm not quite sure why (maybe I fiddled with something in the system I shouldn't have touched?) . When running $update-manager
in a terminal, I get the following error message:
Traceback (most recent call last):
File "/usr/bin/update-manager", line 115, in app.start_update()
File "/usr/lib/python3/dist-packages/UpdateManager/UpdateManager.py", line 212, in start_update update_backend = get_backend(self, InstallBackend.ACTION_UPDATE)
File "/usr/lib/python3/dist-packages/UpdateManager/backend/init.py", line 92, in get_backend from .InstallBackendAptdaemon import InstallBackendAptdaemon

File "/usr/lib/python3/dist-packages/gi/init.py", line 83, in require_version (namespace, version))
ValueError: Namespace Vte not available for version 2.91
Does anyone know the reason for this crash, and (more importantly) how to solve the problem?
