I'm trying to set a system wide proxy, and I'm specifically having difficulties with apt-get for installing applications on my Ubuntu. I'm in a university using a proxy server with username/password. I'm aware of setting a proxy with username and password in the following manner:
But it fails, as a critical example with apt-get. Username contains backslash( \ ) in it and I'm wondering whether that could be a problem for failing. I'd be grateful with any input on this.
