[11.04] apt-get gets stuck during building dependency tree.

[nsmehra]

I have recently done a fresh install of ubuntu 11.04 and still coming to terms with unity interface.

The biggest problem I am currently facing is none of the package managers are working on it so i couldnt update any of the packages.
apt-get gets stuck while building dependency tree.
e.g.
sudo apt-get install vim
Reading package lists... Done
Building dependency tree... 50%

it just hangs there using 100% of one core of my pc. I have left it there running overnight to see any development but its still there at 50% using 100% of one core.

Since the update manager and synaptic package manager use apt-get internally so they are also not working.

i even used the -f option but still it gets stuck at 50%


Any pointers will be helpful.. !! I have already wasted 3 days on this install and still couldnt bring it to the working state.

Thanks in advance.

At this point it starts using 100% of one core and just gets stuck.
