SECONDO

Installation on Ubuntu using apt-get

We provide .deb packages for Ubuntu 26.04 (LTS), 24.04 (LTS), and 22.04 (LTS) on the Intel/AMD architecture (x86_64/amd64). These packages can be used to setup Secondo within a few minutes on your computer. We recommend this installation type for new users, who want to gain first experience with the Secondo system. For advanced users, who want to develop their own extensions, we recommend to build Secondo from the sources.

Installation of Secondo

To install Secondo via apt-get, add the Secondo repository for your Ubuntu release to your package sources. Pick the line that matches your release:

Ubuntu 26.04
echo 'deb [trusted=yes] https://secondo-database.github.io/secondo/apt/ubuntu/26.04/ ./' | sudo tee /etc/apt/sources.list.d/secondo.list
Ubuntu 24.04
echo 'deb [trusted=yes] https://secondo-database.github.io/secondo/apt/ubuntu/24.04/ ./' | sudo tee /etc/apt/sources.list.d/secondo.list
Ubuntu 22.04
echo 'deb [trusted=yes] https://secondo-database.github.io/secondo/apt/ubuntu/22.04/ ./' | sudo tee /etc/apt/sources.list.d/secondo.list
The repository is not signed, which is what the [trusted=yes] option tells apt.

Update the list of the available packages:
sudo apt-get update
Install Secondo and all required dependencies:
sudo apt-get install secondo

Running Secondo

Before starting the first session, each user who wants to work with Secondo has to execute the Secondo installer. This script creates the required environment: 
/opt/secondo/bin/secondo_installer.sh
The installer writes the file ~/.secondorc and makes your shell read it on login. To use Secondo in the current shell without logging in again, enter: 
source ~/.secondorc
Afterwards, each Secondo component can be started from any directory by typing in the appropriate command. The programs that can be started are: Do not start more than one instance of Server or Single User programs accessing the same database directory. For details see the User Manual.
