How to Install, Upgrade, and Update Software

Using CD #2 as a Source
Software may be installed from MEPIS CD #2. This software was placed on CD at the same time CD #1 was created, therefore it should be fully compatible with the software on CD #1. However once you have updated or upgraded from the Internet, you may find that it is no longer possible to install some of the software from CD #2.

Using the Internet as a Source
Software may be installed or updated from the Internet. This software is the most up-to-date, but it may be less stable than the software you already have. Also when updating from the Internet, changing one package may require that a number of other packages be changed at the same time. Proceed with caution.

Selecting the Source with the MSC
Open the MEPIS System Center by clicking on its desktop icon, or

KMenu > Utilites > MEPIS System Center

.

Select

Package Management

If selecting the Internet, you may fine tune your selection by specifying the country form which packages will be fetched, whether you want to include non-US packages, experimental packages, and/or source code packages.

Most users should select to include non-US packages.

Developers and experimenters may want to select experimental and/or source code packages.
