Public bug reported:
I was doing a upgrade using the "sudo update-manager -d" GUI.
Several minutes pass with nothing displayed on the terminal but the GUI
is happily upgrading along. A few times I get weird errors about
something not configuring correctly (didn't have the presence of mind to
write them down). I click OK for all of them. Then, about half a minute
after one of these messages the upgrader crashes with this displayed on
the console:
Error in sys.excepthook:
Traceback (most recent call last):
File "/tmp/tmpFzWtiO/DistUpgradeViewGtk.py", line 416, in _handleException

If you look at /tmp/tmpFzWtiO/DistUpgradeApport.py, line 61, it is trying to
launch "apport-qt". Sure enough, when I try to run this I see:
[14:38:55] ~$ /usr/share/apport/apport-qt
zsh: /usr/share/apport/apport-qt: bad interpreter: /usr/bin/python: no such
file or directory
Since the error happened as a result of the exec call it was probably
passed up the chain as a OSError (the "no such file or directory") that
nobody managed to catch.
well as it turns out, my python must have been in the process of
upgrading at the time because when I do "apt-get -f install" I see this:
The following extra packages will be installed:
gedit lyx-common python2.6-minimal system-config-printer-common
update-notifier-kde
The following NEW packages will be installed:
python2.6-minimal
The following packages will be upgraded:
gedit lyx-common system-config-printer-common update-notifier-kde
4 upgraded, 1 newly installed, 0 to remove and 0 not upgraded.
930 not fully installed or removed.
Need to get 0B/7306kB of archives.
After this operation, 4182kB of additional disk space will be used.
Do you want to continue [Y/n]?
These 5 packages are all the packages that had given me errors and I had
to click through. After installing the problematic packages (this time
it gave no errors) it proceeded to do "Setting up ..." for each other
package that had changed in jaunty (a few hundred more), so basically
the same thing the GUI was doing but now in the terminal.
Things are now working after doing that "apt-get -f install" so it's hard for
me to tell why I was having problems, but it may be worth looking at the error
handling code.
I'm attaching code to add exception handlers around the calls to
"subprocess.call()"
