gnome-control-center does not remove system-wide proxy settings from /etc/environment when switch from manual to automatic mode.

Status changed to 'Confirmed' because the bug affects multiple users.

Hi,

The fix is simple, it just implies adding G_DESKTOP_PROXY_MODE_AUTO to the case block where the system proxy is reset. This leads to the same result than Manual->None->Auto leads.

I'm attaching the debdiff for the precise version, will check the raring version next, and if the bug is still present and still the same, create a fix for that one as well.

The attachment "Debdiff containing the fix for the precise version of gnome-control-center" of this bug report has been identified as being a patch in the form of a debdiff. The ubuntu-sponsors team has been subscribed to the bug report so that they can review and hopefully sponsor the debdiff. In the event that this is in fact not a patch you can resolve this situation by removing the tag 'patch' from the bug report and editing the attachment so that it is not flagged as a patch. Additionally, if you are member of the ubuntu-sponsors team please also unsubscribe the team from this bug report.

The code in raring is completely different, so even if I don't have a raring box to test it right now, I'm assuming it's unaffected by this bug. The code in quantal, however, is basically the same as in precise. I have prepared a patch based on the quantal version, debdiff attached.

Thanks Marga, I've sponsored the updates for both precise and quantal

setting invalid for raring, indeed the code got mostly rewritting in 3.6 and that issue doesn't apply to the current version

Hello Alec, or anyone else affected,

Fails to verify here. If I select 'Automated' and enter a configuration URL, and then click on 'Apply System Wide' I do not even get a polkit prompt for 'admin' access.

Certainly the http_proxy bit in /etc/environment remains.

Indeed, the uploaded version doesn't include my change. The uploaded version has the following changelog:

gnome-control-center (1:3.4.2-0ubuntu0.9) precise; urgency=low

  * debian/UbuntuLogo.png: logo was saying 12.04.1 LTS, go back to just
    use "12.04 LTS" to avoid having to keep updating it (lp: #1116801)

Whereas my patch had the following changelog:

gnome-control-center (1:3.4.2-0ubuntu0.9) precise; urgency=low

  * Added debian/patches/remove-manual-proxy-in-auto.patch to also remove
    the manual proxy setting when in AUTO mode. (LP: #1100587)

I guess the other change was already in the pipeline, but the corresponding fix has not gone in.

Sorry. My previous message was about the precise package, which doesn't yet include the fix, but that was not what the automated message was asking. I suspect Alec made the same mistake.

The quantal package includes the fix. I had wiped my quantal installation, so I'm re-installing it now to check if the fix verifies in quantal, I expect it will.

the fix accepted was for quantal, the one for precise is still in the queue (in fact it got reuploaded recently to include another fix):
http://launchpadlibrarian.net/131131330/gnome-control-center_3.4.2-0ubuntu0.10_source.changes

The precise review might take a bit longer since things are currently frozen for 12.04.2 though

Yes, the package in quantal fixes the issue. Precise is still pending.

Could a SRU team member reject the precise upload? It creates https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1136216

The sound capplet fails to load with those errors:
/usr/lib/control-center-1/panels/libsoundnua.so: undefined symbol: gvc_mixer_ui_device_is_output

Not sure why that just started to happening in that version, there is nothing in the diff that should makes a difference on the symbols/linking and diffing the build logs from 0.9 and 0.10 there is this new line

"dpkg-shlibdeps: warning: debian/gnome-control-center/usr/lib/control-center-1/panels/libsoundnua.so contains an unresolvable reference to symbol gvc_mixer_ui_device_is_output: it's probably a plugin."

but nothing in the linker flags changed...

ok, I found the issue, the diff is buggy, extra lines got added to a new file but the offset of the patch didn't get update which did lead to have the end of file truncated... note for next time: don't try to be too smart about reducing the diff for easier review

I've uploaded a 0ubuntu11 that fixes the bug

Hi,

I can verify that the provided package fixes the issue. HOWEVER, there seems to be no gnome-control-center-data package, which is a necessary dependency and causes problems when installing.

I checked the build logs, but I couldn't find anything there. Also, the missing package WAS built for i386, but not for the other arches.

I forced dpkg installation and the package seems to work, but the missing dependency is a serious issue.

Ok, my mistake, I found the -data package, although it was not in the build results. I guess there's something weird going on with those build results, since the package is actually there, and this is probably related with it being an _all package.

I have re-verified and the uploaded package fixes the issue.

The verification of this Stable Release Update 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 regresssions.
