[Bug 1069745] [NEW] update-manager fatal error while upgrading from precise to quantal, caused by PPA

[Christian Tellefsen]

Public bug reported:

Steps to reproduce:
# Add a third-party repository without support for quantal (e.g. a PPA)
# Start update-manager
# Click upgrade button
# Wait
# Observe a fatal error dialogue, and a  the following fatal error:

<pre>
Traceback (most recent call last):

  File "/tmp/update-manager-Vwi3Ev/quantal", line 10, in <module>
    sys.exit(main())

  File "/tmp/update-manager-Vwi3Ev/DistUpgrade/DistUpgradeMain.py", line 240, in main
    if app.run():

  File "/tmp/update-manager-Vwi3Ev/DistUpgrade/DistUpgradeController.py", line 1764, in run
    return self.fullUpgrade()

  File "/tmp/update-manager-Vwi3Ev/DistUpgrade/DistUpgradeController.py", line 1663, in fullUpgrade
    if not self.updateSourcesList():

  File "/tmp/update-manager-Vwi3Ev/DistUpgrade/DistUpgradeController.py", line 734, in updateSourcesList
    self.sources = SourcesList(matcherPath=".")

  File "/tmp/update-manager-Vwi3Ev/DistUpgrade/sourceslist.py", line 253, in __init__
    self.matcher = SourceEntryMatcher(matcherPath)

  File "/tmp/update-manager-Vwi3Ev/DistUpgrade/sourceslist.py", line 442, in __init__
    dist = DistInfo(f, base_dir=matcherPath)

  File "/tmp/update-manager-Vwi3Ev/DistUpgrade/distinfo.py", line 239, in __init__
    print("WARNING: Failed to read mirror file")

IOError: [Errno 5] Input/output error
</pre>

When I run do-unattended-upgrade, I am told that I have a PPA without
support for quantal ( https://launchpad.net/~pmjdebruijn/+archive
/darktable-release-plus ). The PPA is removed, and the upgrade continues
without errors

Thus I am assuming this error is caused by the presence of a ppa without
support for quantal.
