Why use apt-get upgrade instead of apt-get dist-upgrade?
5 answers
I usually do apt-get update then apt-get upgrade and in some cases apt-get dist-upgrade.
What's the difference?

Excerpt from the apt-get man pages:
update
update is used to resynchronize the package index files from their sources. The indexes of available packages are fetched
from the location(s) specified in /etc/apt/sources.list. For example, when using a Debian archive, this command retrieves and
scans the Packages.gz files, so that information about new and updated packages is available. An update should always be
performed before an upgrade or dist-upgrade. Please be aware that the overall progress meter will be incorrect as the size of
the package files cannot be known in advance.
upgrade
upgrade is used to install the newest versions of all packages currently installed on the system from the sources enumerated
in /etc/apt/sources.list. Packages currently installed with new versions available are retrieved and upgraded; under no
circumstances are currently installed packages removed, or packages not already installed retrieved and installed. New
versions of currently installed packages that cannot be upgraded without changing the install status of another package will
be left at their current version. An update must be performed first so that apt-get knows that new versions of packages are
available.
dist-upgrade
dist-upgrade in addition to performing the function of upgrade, also intelligently handles changing dependencies with new
versions of packages; apt-get has a "smart" conflict resolution system, and it will attempt to upgrade the most important
packages at the expense of less important ones if necessary. The dist-upgrade command may therefore remove some packages. The
/etc/apt/sources.list file contains a list of locations from which to retrieve desired package files. See also
apt_preferences(5) for a mechanism for overriding the general settings for individual packages.
For further information, run man apt-get in a terminal of your choice.
Besides that, I would advise not to run any command, if you don't have at least a rough idea of what it is supposed to do.

Obviously I do. Just wanted to learn. Nothing wrong with asking. I knew basically what was happening but wanted some details since I've not done Unix admin for years and didn't recall Ubuntu details
