Comment 27 for bug 95274

I didn't try joedekangeroe's solution, but another solution is to search for your country's name in the repositories so I searched for Australia, and found myspell-en-au and openoffice.org-thesaurus-en-au. I downloaded both of these packages and restarted openoffice 2.3 and openoffice had already made the link to them (if it doesn't make the link check in oo.org Tools->options->language settings -> default languages that your country/language is selected)

This problem bugs me everytime I get a new version of Kubuntu (I'm currently running Kubuntu 7.10) hopefully someone will fix it soon.
