How To Install conjunct on Debian 11

One-liner install command

For those in a hurry, here's a one-line installation command:

But if you are interested in the detailed steps with descriptions, the following information is for you.

What is conjunct and what are the ways to install it?

Before beginning this tutorial, you will need access to a server or computer running Debian 11. This guide was written specifically with a server running Debian 11 in mind, although it should also work on older, supported versions of the operating system.

Also, make sure you are running a regular, non-root user with sudo privileges configured on your server. When you have an account available, log in as your non-root user to begin.

There are several ways to install conjunct on Debian 11. You can use (links are clickable):

In the following sections, we will describe each method in detail. You can choose one of them or refer to the recommended one.

Install conjunct using apt-get

First, update apt database with apt-get using the following command.

sudo apt-get update

After updating apt-get database, You can install conjunct using apt by running the following command:

sudo apt -y install astronomical-almanac

Install conjunct using apt

Because conjunct is available in Debian 11’s default repositories, it is possible to install it from these repositories using the apt packaging system.

To begin, update apt database with apt using the following command.

sudo apt update

After updating apt database, You can install conjunct using apt by running the following command:

sudo apt -y install astronomical-almanac

Install conjunct using aptitude

If you want to follow this method, you might need to install aptitude first since aptitude is usually not installed by default on Debian 11. Update apt database with aptitude using the following command.

sudo aptitude update

After updating aptitude database, You can install conjunct by running the following command:

sudo aptitude -y install astronomical-almanac

How to upgrade (update) a single package conjunct using apt-get?

First, you will need to update packages index. Run update command as usual:

sudo apt-get update

Next, to upgrade only the conjunct, e.g. single package, you should use the following format with the apt-get command/apt command:

sudo apt-get --only-upgrade install astronomical-almanac

Note that this command will not install any new packages! If you wish to install the package if it doesn't exist you may leave out --only-upgrade part.

sudo apt-get install astronomical-almanac

How To Uninstall conjunct from Debian 11

To uninstall only the conjunct package you can execute the following command:

And lastly, you can run the next command to remove absolutely everything related to conjunct package, e.g.: configurations, data and all of its dependencies. Just use this command:

sudo apt-get -y autoremove --purge astronomical-almanac

Extra info and code examples

The aa program computes the orbital positions of planetary bodies and performs rigorous coordinate reductions to apparent geocentric and topocentric place (local altitude and azimuth). It also reduces star catalogue positions given in either the FK4 or FK5 system. Data for the 57 navigational stars is included. Most of the algorithms employed are from The Astronomical Almanac (AA) published by the U.S. Government Printing Office. The aa program follows the rigorous algorithms for reduction of celestial coordinates exactly as laid out in current editions of the Astronomical Almanac. The reduction to apparent geocentric place has been checked by a special version of the program (aa200) that takes planetary positions directly from the Jet Propulsion Laboratory DE200 numerical integration of the solar system. The results agree exactly with the Astronomical Almanac tables from 1987 onward (earlier Almanacs used slightly different reduction methods). Certain computations, such as the correction for nutation, are not given explicitly in the AA but are referenced there. In these cases the program performs the full computations that are used to construct the Almanac tables (references are provided).

Conclusion

You now have a full guide on how to install conjunct using apt, apt-get and aptitude tools. Also, we showed how to update as a single package and different ways to uninstall the conjunct from Debian 11.
