Linumeric-LPT V1 and V2 can be installed in many ways. At the bottom of the page, manual methods are indicated (available in the initial phase), which, however, do not guarantee correct operation after some time - during manual installation, certain packages and dependencies are installed, which unfortunately change over time and the installation fails.
A special Debian distribution has been prepared for Linumeric-LPT V3, which after installation has everything installed and configured to work with Linumeric-LPT V1, V2 and V3. For a PC it is an ISO installation image of the system, for a Raspberry Pi 4 minicomputer it is an image of the memory card with the system.
Therefore, the recommended and recommended way to install Linumeric-LPT V1 and V2 is to install it according to the instructions for Linumeric-LPT V3.
