Problem:

tim@ubuntu:~$ software-properties-gtk 
ERROR:dbus.proxies:Introspect error on :1.103:/: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NoReply: Message recipient disconnected from message bus without replying

dbus.exceptions.DBusException: org.freedesktop.DBus.Error.ServiceUnknown: The name :1.103 was not provided by any .service files
tim@ubuntu:~$

The "name" value increments each time I try.

I have tried purging and reinstalling dbus e.g.

 sudo aptitude reinstall apt apt-utils aptdaemon aptdaemon-data update-manager update-manager-core dbus

But to no avail.

This is a Xubuntu 18.04 install which until now has given no problems.

more info:

journalctl -e

gives the following output:

It turns out that import requests_unixsocket was failing in /usr/lib/python3/dist-packages/softwareproperties/LivepatchService.py because

 try:
     import dateutil.parser
     import requests_unixsocket

     gi.require_version('Snapd', '1')
     from gi.repository import Snapd
 except(ImportError, ValueError):
     pass

and it was dateutil.parser not importing with an error that module six was not present. The package python3-six was installed (so my package manager said). when I reinstalled this package, software-properties-gtk worked again.

I had the same issue. This did the trick:

sudo apt-get update && sudo apt-get install --reinstall python3-six python3-certifi

For me it worked by reinstalling python3-urllib3:

sudo apt install --reinstall python3-urllib3

Also I suggest to update python3-six, python3-certifi and python3-requests.

Similar to the other answers, I had a bunch of python modules whose versions I'd updated using pip (for some scripts I was testing), which then broke software-properties-gtk, but on Ubuntu 20.04 LTS.

I removed those versions and reinstalled them via apt.

sudo pip uninstall six certifi urllib3 dateutil requests

sudo apt install --reinstall 

    python3-six 

    python3-certifi 

    python3-urllib3 

    python3-dateutil 

    python3-requests 

    software-properties-gtk

I now use virtual python environments (via Anaconda) so this doesn't happen again.
