For scripts, apt-get has the advantage that it doesn't get changed from release to release, but always behaves the same way. > I believe apt is currently recommended.

For upgrading one release to another, apt is currently recommended, but I think it's assumed that you do this by typing the commands rather than just running a script, so you can check for success at each step. > My experience of apt-get and aptitude is that aptitude has a better > resolver and will often clear a medium-sized pile of packages when > apt-get won't.

With anything up to stable, I've never had a problem using apt-get. For example, last week I upgraded a buster (oldoldstable) system that was last upgraded in early March. A mere 171 packages with one command. But sure, for testing and beyond, the quirks in the resolvers will make a difference as there are more packages to upgrade and not even a guarantee that the distribution is complete. Cheers, David.
