I've got an Ubuntu 11.10 system connected via a proxy to the internet, and I would like to install packages via apt-get. When I try to do that I get this error message:
sudo apt-get install libboost-program-options-dev
[...]
Err http://gb.archive.ubuntu.com/ubuntu/ oneiric/main libboost1.46-dev i386 1.46.1-5ubuntu2
407 Proxy Authentication Required
Any ideas?
This method worked for me.....just have a try...
check the file /etc/apt/apt.conf
The contents were,
Acquire::http::proxy "http://<proxy>:<port>/";
Acquire::ftp::proxy "ftp://<proxy>:<port>/";
Acquire::https::proxy "https://<proxy>:<port>/";
This was the reason why you could reach proxy but couldn't get past it, since there is no username password information. So just put that info into it..
Acquire::http::proxy "http://<username>:<password>@<proxy>:<port>/";
Acquire::ftp::proxy "ftp://<username>:<password>@<proxy>:<port>/";
Acquire::https::proxy "https://<username>:<password>@<proxy>:<port>/";
save the file and you are done...
BROTIP: More better add these lines in another file, /etc/apt/apt.conf.d/80proxy. This will ensure that after a version upgrade changes won't be lost.
