I have just installed Ubuntu onto my laptop as a separate partition to my Windows drive. Everything went fine and all updates were installed. Then I went into the software centre and I can't install any apps it gives me

 Package Dependencies cannot be resolved This error could be caused by
 required additional software packages which are missing or not
 installable. Furthermore there could be a conflict between software
 packages which are not allowed to be installed at the same time.

but nothing else is installing and I cant install any app on the software centre Any help will be appreciated. I have had a good look around google and couldnt find anything that worked.

What do you mean by this: 'a separate partition to my windows drive.' Do you have a hard drive specifically made for Windows, and you've installed Ubuntu there, or do you mean you have a Windows partition on a regular hard drive, and you've installed Ubuntu inside that partition??? As for the package installation problem, please post the outputs of 'sudo apt-get update' and 'sudo apt-get upgrade' from a terminal window. – mikewhatever Oct 3 '11 at 0:38
@mikewhatever There are no Windows-only Hard Drives/SSDs/Storage Devices. He meant he has a Drive where Windows is installed, and he made a partition for Ubuntu, Prly The error is self-explanatory , if you have installed anything it has unmet dependencies, or conflicting packages. – Uri Herrera Oct 3 '11 at 1:04
@Uri Herrera Perhaps you should let the OP speak for himself, or is it too much to ask? – mikewhatever Oct 3 '11 at 3:57

You must run a repositories update before you can install anything.

To run an update, go to the update manager, and click on Check for updates.

Alternatively, on the terminal type sudo apt-get update
