Can someone please explain how to search for an application within the shell when apt-get doesn't work. I am currently in a situation where I cannot find the package I want, but now I am stuck with what to do.
$ sudo apt-get install teamspeak-client
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package teamspeak-client
Can someone also explain how to copy large blocks of shell commands into this editor and make it format properly. I'm not indenting every line of commands by 4 spaces every time.
