I always use a proxy to connect to the internet in Windows as well as in previous versions of Ubuntu, but in Ubuntu 11.10 it seems that the proxy settings I set in the GUI are not being applied system-wide.
I can access the internet in Firefox with its own proxy settings. I can access internet in the terminal (i.e. I am able to use apt-get for some small programs). But in Ubuntu software centre or update manager it is not working.

I was having this problem when I first installed Ubuntu 11.10. I don't know which of the following steps solved it, but this is what I did:
Open a terminal
Run
export HTTP_PROXY=http://<myproxy>:<port>
to set up the proxy server for that terminal sessionRun
sudo apt-get update
At this point, the update manager popped up and asked if I'd like to install c. 300 updates, which I did
Restart
Install
dconf
withsudo apt-get install dconf-tools
or Using Software Center![Install via the software center](https://hostmar.co/software-banner)
Run
dconf-editor
, selectsystem
>proxy
>http
and clickenable
(as per the tutorial in teleblog's answer)And now it all seems to work :)
