problem with installing software

[chandanlin]

hi everybody,
Some of the softwares listed in synaptic or in adept are not highlighted. I cannot select them. For example, softwares like libxine-mp3, mplayer, sun-java etc. are not highlighted in the list. I have checked the "propreitory software" and "unsupported" checkboxes. I have also tried to install software through apt -get.

username@neo-den:~$ sudo apt-get install mplayer
Reading package lists... Done
Building dependency tree... Done
Package mplayer is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package mplayer has no installation candidate

Also I have enabled all the repositories.

Does anybody have a solution for this problem

Re: problem with installing software

Step 1 Get a fresh repositories list by following these instructions:
http://www.psychocats.net/ubuntu/sources

Please note that the instructions require you to paste over your existing sources.list. Do not add to the repositories you already have--replace them.

Step 2: Paste this command in the terminal:

sudo aptitude update && sudo aptitude install mplayer

Step 3: If you're still having problems, post the output of that last command as well as this one:

cat /etc/apt/sources.list
