Can not install wine in Ubuntu 9.04

[subhadip_sky]

Hi, I am using Ubuntu 9.04 on my laptop and I can't install wine. I tried the terminal and it showed the following error

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
  wine: Depends: libaudio2 but it is not installable
        Depends: libopenal1 but it is not installable
        Recommends: ttf-liberation but it is not installable
        Recommends: winbind but it is not installable
        Recommends: ttf-mscorefonts-installer but it is not installable
E: Broken packages

I tried the Synaptic package manager also but it didn't help either.
Any help guys?

My guess is that this is because your version is no longer supported; 9.04 reached end-of-life a when 10.10 came out

Thats not the problem I guess because I installed wine on my desktop some 1 or 2 months ago and I didn't face any problem back then. Actually my laptop has only 512 Mb RAM and I can't upgrade it now. So I guess I have no option if I am to stick to Ubuntu.
