dist-upgrade in ubuntu

[Ali Linx (amjjawad)]

>From the man pages for apt:-

*sudo apt-get 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.

*sudo apt-get 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. So, dist-upgrade command may 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.
