[Bug 1034520] Re: dconf-editor does not allow changing authentication-methods for vino server

[Adam Stokes]

Upstream wants to set a boolean for vnc-auth-enable. This would
invalidate the currently proposed patch. My suggestion is to have the
customer roll out with the gsettings alteration until this portion of
the code can be committed upstream. Once that is complete we can file
SRU's and provide the customer with updated packages that would enable
vnc auth through the boolean and still keep the customer satisfied
without requiring any additional alterations on their part.

For now we keep this #woeng, and Ritz can keep an eye on upstream. As
for the resolution of this bug you've been provided a viable workaround
and have allowed the customer to continue their deployment. All that is
left to do now is follow up with upstream.

Title:
  dconf-editor does not allow changing authentication-methods for vino
  server

Status in Ubuntu Advantage Project:
  In Progress

Bug description:
  1. Description of the problem:
  When editing the value /desktop/gnome/remote-access/authentication-methods there is a error "Error setting value: 0-4: unknown keyword" OR "Error setting value: 0-3:unknown keyword" .
  Also it is impossible to set a mandatory value through /etc/dconf/db/local.d/vnc since local.d does not seem to exist in the current 12.04 install. I am not sure if it needs to be created or not. Creating it does not fix anything.

  2. Ubuntu release, software version, Release Number and Architecture of the selected components.
  Distributor ID:	Ubuntu
  Description:	Ubuntu 12.04 LTS
  Release:	12.04
  Codename:	precise

  dconf-tools:
    Installed: 0.12.0-0ubuntu1
    Candidate: 0.12.0-0ubuntu1
    Version table:
   *** 0.12.0-0ubuntu1 0
          500 http://ca.archive.ubuntu.com/ubuntu/ precise/universe amd64 Packages
          100 /var/lib/dpkg/status

  vino:
    Installed: 3.4.2-0ubuntu1.1
    Candidate: 3.4.2-0ubuntu1.1
    Version table:
   *** 3.4.2-0ubuntu1.1 0

  3. How reproducible is the problem?
  Easily reproducible

  4. Steps to Reproduce:
  1. sudo apt-get install vino dconf-tools
  2. open dconf-tools and edit the value /desktop/gnome/remote-access/authentication-methods to VNC.
  3. An error message will show up: "Error setting value: 0-4: unknown keyword" and won't let you choose the option.

   a. Actual Results: "Error setting value: 0-4: unknown keyword" OR "Error setting value: 0-3:unknown keyword"
   b. Expected Results: to be able to set option to VNC

  5. Known Workaround:
  It can be set through gsettings set org.gnome.Vino authentication-methods "['vnc']" although it is not possible to
  set mandatory permissions through /etc/dconf/db/local.d/vnc.

  6. Business Impact and customer deadlines:
  The impact on the customer is MEDIUM however the customer is planning very soon to deploy/upgrade from 10.04 to 12.04 on 30K+ machines and having the mandatory parameter working and through dconf-editor is very important.

  7. Additional information:
  There is no need to send supportconfig since the issue is reproducible on any 12.04 installation.
