I faced problems with Ubuntu while connecting to a proxy server from UBUNTU 11.10
I have tried using network manager but apply system wide won't work.
The software center or update manager doesn't ask for proxy authentication and firefox cant detect the system proxy settings.
I have tried editing gconf http_proxy by giving the proxy authentication manually and tried downloading via apt-get but it was of no use...
When i manually gave proxy settings in firefox it asked for authentication and worked fine.
What can be done here??(please help me out)
