I am trying to compile some LaTeX code which uses the algorithmicx environemt for producing pseudocode. It won't compile and someone told me that from the log file that the packages for these needed environments are too old. How can I update my packages to get the newest versions? From the synaptic package manager I cannot see an update entry for the packages; only full texlive instead of simply tex live

If you post the list of individual packages, someone may be able to give you more details.
