Ubuntu
apt package

apt-get packages all unavailable

Asked by Clark Williams

apt-get tells me packages are not available. I try "apt-get update" but that times out trying to connect to the servers. I'm behind a proxy, but have http_proxy correctly set; the command wget can retrieve web pages successfully.

richardw@ubuntu:~$ sshd
The program 'sshd' is currently not installed. You can install it by typing:
sudo apt-get install openssh-server
richardw@ubuntu:~$ sudo apt-get install openssh-server

This may mean that the package is missing, has been obsoleted, or
is only available from another source

Run:

gksudo gedit /etc/apt/sources.list

and add a hash character to the start of the lines referencing the install CD and save the new file and close gedit. Then run:

sudo dpkg --clear-avail; sudo apt-get update

It should be smooth, is the CD mentioned

Commented out the first line in /etc/apt/sources.list

     # deb cdrom:[Ubuntu 11.10 _Oneiric Ocelot_ - Release i386 (20111012)]/ oneiric main restricted

Didn't recognize any other references to the CD.

apt-get update still fails to connect to the servers:

Had to create a /etc/apt/apt.conf file containing the single line

Acquire::http::Proxy "http://proxyhostname::port";
