/usr/bin/apturl-gtk:AttributeError:/usr/bin/apturl-gtk@47:main:enableChannel:doEnableChannel

[errors.ubuntu.com bug bridge]

[Impact]
Users may not be able to successfully install packages using apturl, especially from other channels from the release archive (ie. using the partner archive).

[Test case]
1) apturl-gtk "apt:adobe-flashplugin?channel=xenial-partner"

[Regression potential]
Possible regressions include a failure to see a package as not being virtual due to not finding the package in the right specified location; also, it may be possible for the UI interface to be shown as completely insensitive (can't be clicked) in the event of a regression.

The Ubuntu Error Tracker has been receiving reports about a problem regarding apturl. This problem was most recently seen with version 0.5.2ubuntu11, the problem page at https://errors.ubuntu.com/problem/7296934db3911cad4d00829c2f458a532da30d62 contains more details.

I was able to recreate this by changing $distro in the ProcCmdline from the a report to xenial. So this command crashes:

/usr/bin/python3 /usr/bin/apturl-gtk "apt:adobe-flashplugin?channel=xenial-partner"

With the following Traceback:

Traceback (most recent call last):
  File "/usr/bin/apturl-gtk", line 47, in <module>
    sys.exit(apturl.main())
  File "/usr/lib/python3/dist-packages/AptUrl/AptUrl.py", line 191, in main
    if self.enableChannel(apturl) != RESULT_OK:
  File "/usr/lib/python3/dist-packages/AptUrl/AptUrl.py", line 99, in enableChannel
    if not self.ui.doEnableChannel(channelpath, channelkey):
  File "/usr/lib/python3/dist-packages/AptUrl/gtk/GtkUI.py", line 135, in doEnableChannel
    apt_pkg.Config.FindDir("Dir::Etc::sourceparts")]
AttributeError: module 'apt_pkg' has no attribute 'Config'

[Brian Murray (brian-murray)]

apt_pkg.Config.FindDir() should be apt_pkg.config.find_dir(), but with that I then get this Traceback:

raceback (most recent call last):
  File "/home/bdmurray/source-trees/apturl/trunk/AptUrl/gtk/backend/InstallBackendAptdaemon.py", line 35, in update
    yield self._run_in_dialog(trans, self.UPDATE)
AttributeError: 'InstallBackendAptdaemon' object has no attribute 'UPDATE'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/defer/__init__.py", line 487, in _inline_callbacks
    result = gen.send(result)
  File "/home/bdmurray/source-trees/apturl/trunk/AptUrl/gtk/backend/InstallBackendAptdaemon.py", line 39, in update
    self._action_done(self.UPDATE, True, False, None, None)
AttributeError: 'InstallBackendAptdaemon' object has no attribute 'UPDATE'

[Brian Murray (brian-murray)]

I've sorted out the UPDATE but that led to yet another one:

Traceback (most recent call last):
  File "/home/bdmurray/source-trees/apturl/trunk/AptUrl/gtk/backend/InstallBackendAptdaemon.py", line 83, in _on_finished
    True, result, None, None)
  File "/usr/lib/python3/dist-packages/UpdateManager/backend/__init__.py", line 80, in _action_done
    self.window_main.start_available(is_cancelled_update)
TypeError: <lambda>() takes 0 positional arguments but 1 was given

Just removing "is_cancelled_update" ends up presenting a dialog box about installing adobe flash that has unclickable buttons.

[Brian Murray (brian-murray)]

Actually the Traceback is the following:

  File "/home/bdmurray/source-trees/apturl/trunk/AptUrl/gtk/backend/InstallBackendAptdaemon.py", line 82, in _on_finished
    True, dialog._transaction.exit == EXIT_SUCCESS, None, None)
  File "/usr/lib/python3/dist-packages/UpdateManager/backend/__init__.py", line 80, in _action_done
    self.window_main.start_available(cancelled_update=is_cancelled_update)
TypeError: <lambda>() got an unexpected keyword argument 'cancelled_update'

[Sebastien Bacher (seb128)]

Seems like Brian&Mathieu got a fix for that uploaded to y
https://launchpad.net/ubuntu/+source/apturl/0.5.2ubuntu12

The upload failed to build though because packagekit 1.0 which has been merged/uploaded in y-proposed is creating issues, should be fine to SRU it though?

[Martin Pitt (pitti)]

Hello errors.ubuntu.com, or anyone else affected,

Accepted apturl into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/apturl/0.5.2ubuntu11.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

[Brian Murray (brian-murray)]

I no longer receive a Traceback with the version of apturl from -proposed and end up receiving a dialog where I can choose to install adobe flash or not.

[Launchpad Janitor (janitor)]

This bug was fixed in the package apturl - 0.5.2ubuntu11.1

---------------
apturl (0.5.2ubuntu11.1) xenial; urgency=medium

  * Fix common crashes (AttributeError in doEnableChannel), due to changes
    in apt_pkg API, etc. (LP: #1566201)

  [ Brian Murray ]
  * Port to proper apt_pkg APIs.

  [ Mathieu Trudel-Lapierre ]
  * Override the start_available and start_error functions from Aptdaemon
    backend correctly to match the passed parameters.
  * Use pkexec rather than gksu to do our external calls to apt-key, install,
    and software-properties, etc; since they need admin privileges.

[Adam Conrad (adconrad)]

The verification of the Stable Release Update for apturl has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.
