Comment 14 for bug 2012110

Hello,

I'm having the same issue.

After the upgrade from Ubuntu 22.10 to Ubuntu 23.04, the update-manager package is broken and will not perform any update.

Symptoms:
- launch update-manager 23.04.2
- screen freezes for a few seconds
- note that the UI shows "You stopped the check for updates"
- note that app has returned:

"Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/defer/__init__.py", line 483, in _inline_callbacks
    result = gen.throw(excep)
             ^^^^^^^^^^^^^^^^
  File "/usr/lib/python3/dist-packages/UpdateManager/backend/InstallBackendAptdaemon.py", line 152, in update
    trans = yield self.client.update_cache(defer=True)
            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NoReply: Message recipient disconnected from message bus without replying"

Steps taken:
- Reinstalled update-related packages with:
"sudo apt reinstall apt apt-utils aptdaemon aptdaemon-data update-manager update-manager-core dbus"

- Reinstalled every single installed package again with this script:"
\#\!/bin/bash
for pkg in `dpkg --get-selections | awk '{print $1}' | egrep -v '(dpkg|apt|mysql|mythtv)'` ; do apt-get -y --allow-change-held-packages install --reinstall $pkg ; done

I am still having the same issue.
