unmet dependencies

[quee]

I have a fresh install on Ubuntu 8.04 and now am trying to install Ruby but come across some unmet dependencies issues.

root:~# sudo apt-get -f install ruby-full irb irb1.8 ruby1.8

ruby1.8 is already the newest version.
ruby1.8 set to manually installed.
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:
irb1.8: Depends: ruby1.8 (>= 1.8.6.111-2ubuntu1.2) but 1.8.6.111-2ubuntu1 is to be installed
ruby-full: Depends: rdoc but it is not going to be installed
Depends: ri but it is not going to be installed
E: Broken packages

Try the reload button in Synaptic and try installing the packages from there.

it's trying to install an older version so refresh the repos

sudo apt-get update

"Reload" button should do it. Nevertheless try apt-get update also. If not getting the correct versions, try changing the repository link.
