Well the update-manager tries to be more 'user friendly' which is why it does not behave the same way as 'apt-get'. Apt-get will actually try and remove packages if necessary, update-manager does not as it is not a recommended process for novice users. Some of the packages an 'apt-get' may remove could be necessary items on that users system.
Here is the manual page for a 'dist-upgrade' dist-upgrade: in addition to performing the function of upgrade, it 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.*** Here is the manual page for a 'upgrade' as performed by the update- manager: 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.*** As you can see, these are 2 very different commands. --- Ubuntu Bug Squad volunteer triager http://wiki.ubuntu.com/BugSquad -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/810936 Title: Update Manager offers partial upgrade in Lucid Lynx To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/810936/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
