Bug Description

[Impact]

The Synaptic backend in apturl is non-functional. Trying to use it makes
apturl crash with Python error message.

The fix for this issue is provided in the debdiffs attached to the report.

It's a long-standing bug which is present in all current Ubuntu releases,
starting from Trusty. Would be nice to get it finally fixed. A non-working
backend isn't good at all, especially when the only other backend (aptdaemon)
might be removed soon, as stated in bug 1673258.

[Test Case]

The easiest way to make apturl use the Synaptic backend (without removing
aptdaemon from the system) is to set the environment variable when launching
it from the terminal:

$ UPDATE_MANAGER_FORCE_BACKEND_SYNAPTIC=1 apturl apt://gnome-calculator

You can use any other package which isn't installed. I chose gnome-calculator
as it wasn't installed in my Xubuntu and Ubuntu MATE systems.

The result of this will be crash of apturl with Python error message.
The package won't be installed.

[Regression Potential]

The patch only affects the Synaptic backend. It doesn't affect aptdaemon
backend or any other parts of code. Since the Synaptic backend was broken
before, it's not possible to break it further with some regression.

[Original Description]

System: Xubuntu 14.10
apturl version: 0.5.2ubuntu4

If you'll tell apturl to use the Synaptic backend (by either removing aptdaemon from the system or specifying UPDATE_MANAGER_FORCE_BACKEND_SYNAPTIC=1 before apturl in the terminal), it crashes with this error:

$ UPDATE_MANAGER_FORCE_BACKEND_SYNAPTIC=1 apturl apt://gcalctool
/usr/lib/python3/dist-packages/AptUrl/gtk/GtkUI.py:4: PyGIDeprecationWarning: Since version 3.11, calling threads_init is no longer needed. See: https://wiki.gnome.org/PyGObject/Threading

The effect is exactly the same in Xubuntu 14.04 (apturl's version is also the same, 0.5.2ubuntu4).

So here's the fix for 17.10. Now Synaptic backend should work.

I've removed the part of debdiff with modifications to po/apturl.pot file as it's not relevant to the issue.

Unfortunately, Synaptic backend still fails in 18.04, this time due to absence of gksu. I'll try to adapt the patch to pkexec (which Synaptic supports).

For Trusty and Xenial, the patch is working fine.

This is the updated debdiff which adds switch from gksu to pkexec to make Synaptic actually run.

New debdiff makes Synaptic backend finally work in 18.04, so the old debdiff is removed.

Sponsors: please upload the updated package...

Hmm... the updated patch is also needed for 18.10, as version 0.5.2ubuntu15 still tries to use gksu.
