Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

Status changed to 'Confirmed' because the bug affects multiple users.

[Colin Watson (cjwatson)]

This is specific to the synaptic backend; using the newer aptdaemon backend by installing python-aptdaemon.gtk3widgets should be a workaround. I'm encountering this while porting update-manager to Python 3 (where the modules necessary for the aptdaemon backend aren't yet packaged), so I'll see if I can figure out a fix.

This bug was fixed in the package update-manager - 1:0.163

---------------
update-manager (1:0.163) quantal; urgency=low

  [ Colin Watson ]
  * Isolate tests from local configuration in
    /etc/update-manager/release-upgrades.d/.
  * Use Python attributes rather than GObject.get_data and GObject.set_data,
    which have been removed upstream (LP: #1009859).
  * Switch default view class to Gtk3 and replace python-gobject dependency
    with python-gi.
  * Port away from old-style apt.Package candidateFoo and installedFoo
    properties, preferring candidate.foo and installed.foo. In a number of
    cases we have to check whether candidate/installed is non-None first.
  * Use apt_pkg.version_compare rather than apt_pkg.VersionCompare.
  * Use apt_pkg.uri_to_filename rather than apt_pkg.URItoFileName.
  * Use apt_pkg.TagFile (and related new-style API) rather than
    apt_pkg.ParseTagFile.
  * Use apt_pkg.PackageManager rather than apt_pkg.GetPackageManager.
  * Use apt_pkg.Acquire rather than apt_pkg.GetAcquire.
  * Use mark_foo/marked_foo rather than markFoo/markedFoo.
  * Use apt_pkg.ActionGroup rather than apt_pkg.GetPkgActionGroup.
  * Use apt_pkg.ProblemResolver rather than apt_pkg.GetPkgProblemResolver.
  * Use apt_pkg.read_config_file rather than apt_pkg.ReadConfigFile.
  * Use new spelling of apt_pkg.DepCache methods.
  * Rename several local cache methods to PEP-8 style to avoid showing up in
    the output of /usr/share/python-apt/migrate-0.8.py.
  * Use apt_pkg.size_to_str rather than apt_pkg.SizeToStr.
  * Use apt_pkg.PackageManager.get_archives rather than
    apt_pkg.PackageManager.GetArchives.
  * Use apt_pkg.Acquire.fetch_needed rather than
    apt_pkg.Acquire.FetchNeeded.
  * Use new spelling of apt_pkg.Package/Version/Dependency methods.
  * Use apt_pkg.pkgsystem_lock rather than apt_pkg.PkgSystemLock.
  * Use new spelling of apt_pkg dependency parsing methods.
  * Use new spelling of apt_pkg.SourceList methods.
  * Bump python-apt (build-)dependency to >= 0.8.0.
  * Add a scheme for excluding false positives from the pyflakes test, and
    enable it by default.
  * Rearrange the OptionParser workaround from 1:0.154.5 to work with Python
    3, using gettext or ugettext as appropriate.
  * Always pass bytes to hashlib.md5.update.
  * Fix DistUpgradeAptCdrom to account for gzip files being opened in binary
    mode.
  * Convert the last use of os.popen to subprocess.check_output, which makes
    it easier to read str rather than bytes. (This requires Python 2.7.)
  * Decode bytes read from urlopened file objects.
  * UpdateManager/backend/InstallBackendSynaptic.py
    - Keep a reference to the data tuple passed to GObject.child_watch_add
      to avoid attempts to destroy it without a thread context
      (LP: #724687).
    - Open temporary synaptic selections file in text mode.
  * Define __bool__ rather than __nonzero__ method in Python 3.
  * sort(cmp=) and sorted(cmp=) no longer work in Python 3. Use appropriate
    key= arguments instead.
  * Fix ResourceWarning while reading /proc/mounts.
  * Make update-manager-kde depend on psmisc, for killall.
  * DistUpgrade/DistUpgradeView.py:
    - Use floor division in Fuzzy...
