Behind a proxy, can't access repositories (407 error) HELP

[MrPaez]

Hey this issue has been driving me mad. I am at work and I have setup a test desktop running 7.10. At my workplace we have an ISA proxy/firewall.

Whats happening is that when i try to run update or download/install software from the synaptic packager manger I get an error message stating: (407 ISA authentication...blah..blah)

I have put in the correct credentials for access to the proxy, as well as the correct IP for the proxy. I have sufficient rights (domain admin.) so thats not an issue. I have placed the exact same proxy setting config. information in the following areas of 7.10

For Firefox which works and I can get out to the internet. Under System>Preferences>Network Proxy and lastly under Administration>Synaptic Package Manager>Settings>Preferences>Network .

I also created an /etc/apt/apt.conf file with the following lines:
Acquire::http:roxy "http://[[user][ass]@]host[ort]";
Acquire::ftp:roxy "http://[[user][ass]@]host[ort]";

without the brackets however.

If anyone has any suggestions on resolving the authentication issues with our environment's ISA I would appreciate it.

PS: sudo apt-get update or any CLI commands generate the same error.

PSS: I rather not download each update and manually install it. Thats why I am looking to resolve this issue.

Have you tried setting the proxy in synaptic (Settings --> Settings --> Network)?

Jocko, I am not sure i follow where you are suggesting to change the syanptic settings.

I have set it under Administration>Synaptic Package Manager>Settings>Preferences>Network is this the location that you are referring to?

yes, that's what I meant. I translated from swedish, so I guessed wrong on one of the "Settings"...
I guess it didn't work, then I can't help you...

I have similar difficulties here at uni.

I believe it has something to do with command line apps not using the Gnome proxy settings. For example Firefox would work but something like Links2 would not. I can access the university's sites in Links2 without proxy configured but not any outside network.

Synaptic and Update Manager both use a command line back end and here I would suggest we try to fix the proxy issues first. But I have no idea how to do this.

I'm having the exact same problem, but with an ubuntu server being behind an ISA server.
Not being able to access the repositories is quite frustrating.

Thanks this solved my problem too.

You might want to check the firewall logs to see if its being blocked. Synaptic MAY use a blocked port on the firewall

Another thing to try is to use apt to see if that works
