Synaptic, update-manager, apt-get and wget should share proxy settings

Thanks for reporting this bug and any supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here. Thanks for taking the time to make Ubuntu better!

Synaptic sometimes fails too when reconfiguring it to direct connection. If you configure it to connect via proxy and then you reconfigure it to direct connection it still tries to connect via proxy. I think that it would be interesting that synaptic accesses the network using gnome proxy configuration.

I too have been bedeviled by this bug for a long time. I thought Intrepid might have a fix. What I don't understand is why NTLmaps works for some but not for others. I'm behind a proxy whose port is 800; those I've seen where NTL works use port 5865. Not sure if that's germaine, but it's something I've noticed.

This is a really bothersome bug, because I'm unable to update any computers in our lab here at school. They're still running Ubuntu Gutsy -- with no updates since it was installed.

Confirmed on jaunty !!!!!

Please this is horrible when we change often proxy configuration.

I think this is a security bug too because in that case synaptic AND network proxy save at the same time the squid login & password.

me too - bump

This get's me twice every day when I change between my work and home networks

Confirmed on Karmic - Alpha 5.

A fix needs to be contributed to utilise the Network Proxy Preferences tool to ensure that all package management applications honour the settings defined.

Thanks for your bugreport.

What proxy settings do you have? Is this a proxy that requires authentication? The bug should be fixed already in jaunty (unless authentication is used). What happens if you open a gnome-termianl and type:
$ echo $http_proxy ?

Yes, this is a proxy that requires authentication.
The results of $http_proxy does not include the authentication
credentials if it is set "system wide" on Karmic Alpha 5:

http_proxy=http://proxy.domain.com:8080/

For $http_proxy to work, I use the following:

http_proxy=http://username:<email address hidden>:8080/

Absolutely NOTHING works for me trying to get updates. $http_proxy output is http_proxy=http://myusername:<email address hidden>:800/ -- because the proxy port is 800. I've tried 5865, 8080, and others that I've seen posted in "fixes" that don't work for me.

I am absolutely at my wits' end in trying to figure this out. I started with Gutsy, updated to Hardy in hopes there was a fix; then to Intrepid, hoping the same; then to Jaunty; now to Karmic, and still no joy.

I've tried setting Network Proxy with authentication and without. With direct connection. Tried Synaptic with proxy settings and authentication, also with direct connection. 407: Proxy authentication required in all cases.

Has anyone found a solution to this maddening problem?

after setting global proxy settings in network proxy, also edit /etc/wgetrc and add a line http_proxy = http://username:password@host:port

edit the file as root obviously. everything then seems to work :)

oh similar for https as well. scroll down in wgetrc and you'll see a section about proxies.

After upgrading to ubuntu10.10,I can not install packages in the terminal using the command "apt -get install packagenames" with the environment variable "http_proxy" set properly in the terminal.I have to set the proxy in the apt.conf file in the /etc/apt directory or use the "-o Acquire::http::Proxy" option in the command line.But in the man page of apt.conf, it still writes that "The http_proxy environment variable will override all settings".I don't know whether this is a bug or not.Maybe it's just time to update the man pages.

I think the importance is labelled wrong, but I can't change it.

Schools, most other public sector organisations, and most medium-to-large businesses access the web from behind a firewall that blocks all web traffic except through a proxy. This means that anyone at those organisations who uses ubuntu is going to find that web pages can't use flash, several of their favourite fonts won't install, etc.

I think this is a serious obstacle to solving bug 1.

Indeed, this is the case. I'm in a school, and I have spent probably a total of 1000 hours trying to configure my Ubuntu (all the way back to 6.04) for updates -- all to no avail. I've tried everything. Absolutely this is the most annoying bug in any operating system I've ever encountered.

As noted in other comments setting the 'system wide proxy' did not work for me, even though I can see the env vars set correctly. The following fixed my problem with 'flashplugin-installer'

sudo gedit /etc/wgetrc

# You can set the default proxies for Wget to use for http, https, and ftp.
# They will override the value in the environment.
https_proxy = http://WWW.XXX.YYY.ZZZ:####/
http_proxy = http://WWW.XXX.YYY.ZZZ:####/
ftp_proxy = http://WWW.XXX.YYY.ZZZ:####/

# If you do not want to use proxy at all, set this to off.
use_proxy = on

Oh yes, I also needed to do this to get any updates to work:

sudo gedit /etc/apt/apt.conf

Acquire::http::Proxy "http://WWW.XXX.YYY.ZZZ:####";

Thank you for taking the time to report this issue in the One Hundred Paper Cuts project. However, I am rejecting this as a paper cut because it is not a simple usability issue in default or featured applications, but instead a larger, complex problem.
Don't worry, I'm ONLY setting this as Invalid for the One Hundred Paper Cuts project.

Because there appears to be quite some uncertainty about where this bug is caused and how widespread it is, I'm setting the statuses of this bug in the Ubuntu packages to Incomplete and the importances to Undecided. This should also help to make this bug show up on the radar of the right people again.

Currently in Precise, the development release of Ubuntu that will become 12.04, if you setup a network proxy in the Network portion of System Settings this will be set in /etc/environment and /etc/apt/apt.conf. Subsequently, update-manger, apt, synaptic and wget will all use the same settings. So I am setting this to Fix Released.

I don't think this issue is fixed in 12.04 beta.

I have set my proxy settings in Network Settings, in ~/.bashrc, in /etc/apt.conf and in /etc/wgetrc (as I used to do in 10.04 and 10.10). Web browsers work, wget works and updates (both graphical and via apt-get) work, except for the flashplugin-installer, which times out when trying to download the file:

flashplugin-installer: downloading http://archive.canonical.com/pool/partner/a/adobe-flashplugin/adobe-flashplugin_11.2.202.233.orig.tar.gz

  File "/usr/lib/python2.7/socket.py", line 571, in create_connection
    raise err
IOError: [Errno socket error] [Errno 110] Connection timed out

I never heard of /etc/environment, and looking at the file I see nothing proxy related:

It's definely a regression since with this very configuration I could update flash in 10.04 no problem. Should I open a new bug report or continue with this one? Also if you need more info on my system I'll be happy to provide it, I'm running an updated 12.04, with 3.2.0-23-generic kernel, x86_64.

I also continue to see this issue in 12.04. Like @ender46 I have my proxy set up in Network Settings, apt.conf and /etc/wgetrc and also as an environment variable for root. Despite this, when flashplugin-installer and ttf-mscorefonts-installer try to download files the downloads time out.

Running apt-get upgrade through a proxy:
