They are optional dependencies. Software can run without optional dependencies, just some options are missing if those dependencies aren't installed. Hard dependencies are dependencies that are needed by the software. Recommended and suggested dependencies are Debian/Ubuntu terms for optional dependencies. The default is that recommended dependencies are automatically installed too and suggested dependencies are not automatically installed. There is something else to consider regarding upgrades, the difference between upgrade (under no circumstances are currently installed packages removed, nor are packages that are not already installed retrieved and installed) and dist-upgrade (a "smart" conflict resolution system, and it will attempt to upgrade the most important packages at the expense of less important ones, if necessary). However, claims to make it more user-friendly for some so called "averaged" user are hard to fulfil, solutions always need to be solutions based on the common ground. User-friendly doesn't mean that a non restricted free operating system could be used without a learning curve or without any self-responsibility. Even if the package management would be able to read the mind of a user, it only could do what's in the mind of the user. The package management is unable to read the mind, but a user can configure the package management not to use the defaults. The defaults of Ubuntu try to fit to what is common ground of "averaged" users. Somebody already pointed out, the only enhancement could be an undo option based on the package management's log (history), but that could become very tricky. I bet it will cause more trouble, than enhance user-friendliness. -- http://www.grundgesetz-gratis.de/ -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
