update-manager hangs in 17.10

What is the full output of:

sudo apt-get update

Artful is end of life (EOL) in a matter of weeks, so you may want to upgrade to Bionic sooner rather than later. Bionic is LTS and supported until April 2023.

Do you see the same behaviour when you start update-manager with user-rights (i.e. without sudo)?

Output from "apt-get update is pasted below.  It may be relevant to
observe that installing applications via synaptic seems to work fine;
indeed I have used synaptic to re-install update-amnager (a couple of
times now.)

Run:

sudo apt-key adv --recv-key --keyserver keyserver.ubuntu.com CAEB3DC3BDF7FB45

That will import the key you need. I also suggest you disable the install media as a package source.

Yes,  Normally, I get update notifications passively, and just click
"install now";  in fact, that was how I first noticed the problem.  Of
course, I can also use the applications menu to run the update manager.
Neither of these methods run in a terminal, and just hang with a blank
window. ort.

Running as "sudo update-maanger: (not in background) generates the error
report I initially attached.  I just now ran without "sudo" (from
terminal, not in background), and get the dame error.

I can'e help but think the problem is finding the right python libs.  My
machined is complicated in that I have three, different Python
installations: v2.7 (via Synaptic), Anaconda's v.3.5, and v.3.6.  This
baroque arrangement is dictated by some third-party applications which
require a specific version.  I use a set of scripts to set PYTHONPATH
and execuatble as needed.  The erros reported were with the 3.6
environment. (That's how I've always run update-manager.  But I've also
tried with 2.7 environment, to no avail. )  I note that the three
modules shown in synaptic, searching for "updte-manager" include
"python3-update-manager".

Before we try tackling the python problem you should bring you package management system back into a consistent state:

Run the program
software-properties-gtk
and disable the sergiomejia666/xresprobe ppa
and disable (untick) the installation CD-ROM

Then re-execute
sudo apt-get update
and copy/paste the output that we can check whether there are still errors.

Manfred, "actionparsnip",

Sorry for the delay; I've been tied up with other problems.  I thought
we were on dual tracks here, but I see the same return address  for both
Manfre Hampl and "actionparsnip"

I ran "sudo apt-key adv --recv-key --keyserver keyserver.ubuntu.com
CAEB3DC3BDF7FB45" , followed by another try at running "update manager.
The output is belowe the first set of ***'s.  Lots of output, but the
bottomline (literally) is still a "failed to execute, permission denied"
error.

Then, pursuant to the second email, I ran "software-properties-gtk";
output under second set of ***'s. Worse news yet -- it doesn't run!
Also errors with "failed to execute, permission denied" error. (and
therefore couldn't disable the ppa and cd-rom.)

How can my computer have gotten so sick from what I thought was a
relatively straight-forward operation to make room on the boot dis!?

Totally flumoxed.

Bravo! Yes, that was what it needed.

Please mark the question as "solved" if everything is working as desired.

Problem resolved by reinstalling dbus modules:
sudo apt-get install --reinstall dbus python-dbus python3-dbus
