If all Packages are showing with Blue text then the 'if newer ver' option is fine. But if there is a mix of Red and Blue use 'unconditionally'. This method of Package Management is especially helpful in Managing packages in repo's like those in the video - unstable or factory repo's. Or in multi-media situations where everytime you click on a package to update (eg;Amarok) say in Packman you get dependency errors. You can temporarily disable the check box for that and re-enable it before pressing accept. This lets you mark all the updates/upgrades/changes without interference. By the time you finish doing 'update all' in the various repo's - when you check at the end for dependencies, it is usually all OK. Read carefully any errors you do get, it is a bit confusing but it is usually fairly easy to opt your way through it. Or save the the error to file with the expert button.
