[Bug 1232066] Re: click unregister on preinstalled app causes exception

[Launchpad Bug Tracker]

This bug was fixed in the package click - 0.4.9

---------------
click (0.4.9) saucy; urgency=low

  * Explicitly build-depend on pkg-config, since it's needed even if the
    PackageKit/GLib-related build-dependencies are removed for backporting.
  * Remove some stray documentation references to Ubuntu 13.04.
  * Ensure that the user's overlay database directory exists when
    unregistering a preinstalled package (LP: #1232066).
  * Support packages containing code for multiple architectures, and
    document the "architecture" manifest field (LP: #1214380, #1214864).
  * Correctly pass through return values of commands as the exit status of
    the "click" wrapper.
  * Extend "click info" to take a registered package name as an alternative
    to a path to a Click package file (LP: #1232118).
  * Force unpacked files to be owner-writeable (LP: #1232128).

Bug description:
  Hi,

  when tring to use unity-scope-click to remove a preinstalled package (dropping-letters) I get a pkcon error in the scope; there's a click crash file with a traceback:
  PythonArgs: ['/usr/bin/click', 'unregister', '--user=phablet', 'com.ubuntu.dropp
  ing-letters', '0.1.2.2']
  Traceback:
   Traceback (most recent call last):
     File "/usr/bin/click", line 84, in <module>
       sys.exit(main())
     File "/usr/bin/click", line 79, in main
       mod.run(args)
     File "/usr/lib/python3/dist-packages/click/commands/unregister.py", line 57,
  in run
       registry.remove(package)
     File "/usr/lib/python3/dist-packages/click/user.py", line 295, in remove
       osextras.symlink_force(HIDDEN_VERSION, path)
     File "/usr/lib/python3/dist-packages/click/osextras.py", line 77, in symlink_
  force
       os.symlink(source, link_name)
   FileNotFoundError: [Errno 2] No such file or directory: '/opt/click.ubuntu.com/
  .click/users/phablet/com.ubuntu.dropping-letters'

  Indeed, /opt/click.u.c is empty and .click doesn't exist there.

  Cheers,
