Software & Updates crashes and will not open
Solution 1
I had the same issue, Ubuntu 16.04, 64-bit and a reinstall of all the supporting packages:
sudo aptitude reinstall apt apt-utils aptdaemon aptdaemon-data update-manager update-manager-core dbus
solved the issue. For note, a temporary workaround was to run sudo aptd
in another terminal before running update-manager
, and then update-manager
was able to connect to aptd
over dbus.
Unfortunately, I can't determine which package was the precise fix now that my issue is solved but if you try reinstalling each one-by-one, you can report back. A number of packages are/were broken on my system by a failed install resulting in odd issues like this one because of missing files, permissions and scripts; reinstalling packages is fixing these problems.
Solution 2
I was about to reinstall the system until I found davidjb's solution.
So,
sudo apt-get install aptitude
followed by
sudo aptitude reinstall dbus
solved this problem for me.
Solution 3
to add my 2 cents: Ubuntu-Mate 16.04, installed 15-June-2017, all updates. Similar problem appeared (dbus.exceptions.DBusExcept etc), solved by:
sudo aptitude reinstall python-pkg-resources python3-pkg-resources

I am unable to open the Software & Updates configuration window in System Settings. The best I have been able to do to understand what is going on is the following output after opening System Settings from terminal and clicking Software & Updates:

The same error occurs when executing
software-properties-gtk
(because AFAIK, it is one and the same).Software Updater has been having some similar issues, and often crashes with this error:

Overall, it seems like Python and GTK are vomiting all over the place, but I don't know how to fix it.
There have been various other related issues such as being unable to install packages from the Software Center, or a variety of crashes from trying to update on startup.
I have already tried reinstalling software center with no luck, and am afraid to attempt this solution as the people in the comments say it's a bad idea. I have come here after finding a lack of answers everywhere else.
Edit:
Interestingly, I've encountered another error that is very similar in
nvidia-settings
. Error output is shown below when trying to save xorg.conf settings.$ sudo nvidia-settings ** Message: PRIME: No offloading required. Abort ** Message: PRIME: is it supported? no Package xorg-server was not found in the pkg-config search path.

And later, when trying to update
pip
, I find this error:$ sudo pip install --upgrade pip The directory '/home/max/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

Thomas Carlisle over 5 yearsWith Ubuntu 18.04 in 2019 I had this issue, and chose to just reinstall aptdaemon, aptdaemon-data, and dbus. That resulted in software-properties-gtk working as expected.

alvaro.canepa about 4 yearsThanks, this worked for me.

WinEunuuchs2Unix almost 4 yearsNote after reinstalling
dbus
you get the message:A reboot is required to replace the running dbus-daemon.
-
WinEunuuchs2Unix almost 4 yearsI never rebooted and it appears (ironically) that
sudo apt install --reinstall apt
is the only I required to getsudo software-properties-gtk
working again without dbus permission denied errors. -
jamboNum5 over 3 yearsThe aptd command was missing for me, I ended up downloading each .deb from Launch pad and installing with dpkg -i launchpad.net/ubuntu/+source/aptdaemon

morganwahl almost 3 yearsThis worked for me with one more simplification: just
sudo apt reinstall dbus
.aptitude
is not necessarily installed, butapt
presumably will be.
