Note: The user installing Xentara needs the privileges necessary to execute the sudo(8) command. This is usually accomplished by adding the user to the sudo user group. This can only be done by the root user, or by another user that already has sudo access.

Under Linux, Xentara is distrubuted using aptitude, the standard Debian package manager. Xentara and Xentara plugins can either be installed using the Xentara installer script, or manually using the apt(8) command line utility.

Xentara is available for the following Debian architectures:

amd64: 64 bit x86 systems (Intel/AMD)
arm64: 64 bit ARM systems (ARMv8-A with AArch64)
armhf: 32 bit ARM systems with harware floating point support (ARMv7-A with VFPv3)
armel: 32 bit ARM systems without harware floating point support (ARMv5T and ARMv6)

Installing Xentara using the installer script

The easiest way to install Xentara under Linux is using the Xentara Installer script, which can be downloaded under https://download.xentara.io/Linux/xentara-installer.sh. To install Xentara using the installer script, proceed as follows:

Download the installer script from https://download.xentara.io/Linux
Open a terminal and change to the directory into which you downloaded the installer script using cd.

Make the installer script executable be entering the command chmod a+x xentara-installer.sh.
Run the script using ./xentara-installer.sh
Follow the on-screen instructions

The installer script will add the Xentara repository and the signing key to the aptitude configuration, and install Xentara using apt(8). The script will then prompt you to install additional plugins.

Once Xentara has been installed, you can update, add, or remove packages using the apt(8) tool manually. You can also run the installer script again, which will update Xentara and allow you to install additional plugins.

Manually configuring the Xentara aptitude repository

You can also manually configure aptitude to use the Xentara repository, by placing a file with the extension “.list” into the directory /etc/apt/sources.list.d/. The file must have the following contents:

deb https://download.xentara.io/apt stable non-free

You can replace stable with a specifi Xentara version number to prevent updates to higher Xentara versions. To only receive updates for Xentara 1.1, but prevent upgrading to Xentara 2.0, for example, you can use the following text:

deb https://download.xentara.io/apt 1.1 non-free

To enable aptitude to verify the authenticity of the packages, you must also install the Xentara signing key. Download the key from https://download.xentara.io/apt/support-files/embedded-ocean-archive.gpg, and copy it into the directory /etc/apt/trusted.gpg.d/.

Afterwards, run apt update to fetch the list of packages. You can then install xentara using apt install xentara.
