The global upgrade enables you to upgrade your system to the latest version without having to queue each package upgrade manually.
Synaptic Package Manager provides two global upgrade methods:
The default upgrade method queues upgrades of installed packages only. If the later version of a package depends on not installed packages or conflicts with an already installed package, the upgrade will not be queued.
Dist-Upgrade tries to resolve package conflicts intelligently. This includes installing additional required packages and prefering packages with higher priority.
![]() | Upgrades to later operating system major releases have to be done with the dist-upgrade method, e.g. from Conectiva 9 to Conectiva 10 or from Debian Woody to Debian Sarge. |

Query the package repositories for the latest version of the packages:
