Solus is an operating system for x86-64 architecture based on the Linux kernel which was previously known as Evolve OS. This OS supports Budgie, MATE, GNOME, and KDE Plasma desktop environments.

Software Packaging in solus

Solus Linux applies an eopkg(Evolve OS Package) package management system which ensures the delivery of software to end-users. Eopkg is based on PiSi(Packages Installed Successfully as Intended) from Pardus which is a distribution developed with the support of the government of Turkey. Eopkg offers tools such as installing, removing packages, searching, and managing repositories. Note that Solus supports its package management with the help of other package managers such as Flatpak and Snap packages.

Applications availability

When you install Solus on your computer, it will come with a pre-installed range of software. The additional software which is not installed on default can be downloaded from the software center. Also, with the help of the .eopkg package format on Solus, you can easily, manage your packages starting from installation to deletion.

Eopkg Package Manager Usage

A package manager is a useful tool in any Linux distribution. For instance, when packages in Solus start piling up, it will become tedious and complex to handle the versions and dependencies in those packages. Hence, you will require an Eopkg package manager to assist in installing, configuring, upgrading, and removing packages in your Solus system via the use of simple commands. This guide will take you through the introduction to packaging managing in Solus and the various long and short versions of commands used.

Upgrade packages / system

It is always advisable to keep on upgrading your Solus operating system. In that case use this command:

sudo eopkg upgrade

Keep in mind that you can upgrade a specific package on your system.

sudo eopkg upgrade package_name

An Example:

$ sudo eopkg upgrade vlc
Updating repositories
Updating repository: Solus
eopkg-index.xml.xz.sha1sum     (40.0  B)100%      0.00 --/- [--:--:--] [complete]
Solus repository information is up-to-date.
No packages to upgrade.          

Installing Packages

In Solus, it is possible to install a package or packages using this command:

sudo eopkg install <package>

For example, let’s install VLC using the install or it command. When asked whether you want to continue with the installation process, type Yes and the package will be installed.

$ sudo eopkg it vlc
Following packages will be installed:
libdvbpsi  libebml  libmatroska  libmodplug  libupnp  protobuf  qt5-svg  qt5-x11extras  sdl1-image  vlc
Total size of package(s): 12.52 MB
There are extra packages due to dependencies. Do you want to continue? (yes/no) yes

Uninstalling software

In case you want to uninstall or remove specific software from your system, use the commands below.

sudo eopkg remove package_name
sudo eopkg rm package_name

Let’s go ahead and uninstall the package we have already installed which in this case is VLC, using the remove or rm command.

$ sudo eopkg remove vlc
The following list of packages will be removed
in the respective order to satisfy dependencies:
Removing package vlc
Removed vlc

Reinstalling/Remove Packages

There are certain instances where you are experiencing issues with an already installed software, reinstall it using the following commands:

sudo eopkg install --reinstall package_name

For Example:

$ sudo eopkg install --reinstall vlc
Total size of package(s): 10.36 MB
Downloading 1 / 1
Package vlc found in repository Solus
vlc- [cached]
Installing 1 / 1
vlc- [cached]
Installing vlc, version, release 147
Extracting the files of vlc
Installed vlc

Search package / packages

You can find out whether a package is available in the Solus repository by following this command.

sudo eopkg search package-name
sudo eopkg sr package-name

When you search for a package, you get results and more details about the particular package.

$ sudo eopkg search vlc
vlc-dbginfo                    - Debug symbols for vlc

Repository Managing in Solus

Solus eopkg package manager allows us to use multiple repositories on our system.

Add a Repository

In this case, we will add a Local repository in Solus. Start by installing the local profile.

sudo eopkg install solbuild-config-local-unstable

Since the solbuild-config-local-unstable package lives in /var/lib/solbuild/local, refresh the index.

sudo eopkg index --skip-signing /var/lib/solbuild/local/ --output /var/lib/solbuild/local/eopkg-index.xml

Continue by adding your repository. Here are the commands you should apply.

sudo eopkg add-repo Name Url
sudo eopkg ar Name Url

In our case, let’s add a Local repository.

$ sudo eopkg ar Local /var/lib/solbuild/local/eopkg-index.xml.xz
Repo Local added to system.
Updating repository: Local
Package database updated.

You can view the list of available repos.

 $ eopkg lr
Solus [active]
Local [active]

Remove a Repository

Note that it is possible to remove a repository from your Solus system.

sudo eopkg remove-repo Name

For instance, we can remove the Local repo we just added.

$ sudo eopkg remove-repo Local
Repo Local removed from system.

Enable a Repository

We can enable a repository using the following command.

sudo eopkg enable-repo Name

An Example includes:

$ sudo eopkg enable-repo Local

Disable a Repository

To stop a repository from functioning, we use this:

sudo eopkg disable-repo Name

For instance:

sudo eopkg disable-repo Local

Build eopkg Packages

Solus provides commands that will help you build and run packages. The process of building packages is centered around the Solbuild program. Let’s start by installing a component by the name system.devel that will assist in creating packages.

sudo eopkg it -c system.devel

Continue by installing Solbuild itself.

sudo eopkg install git solbuild arcanist solbuild-config-unstable

Results after installing solbuild.

solbuild-config-unstable- [cached]
Installing solbuild-config-unstable, version, release 36
Extracting the files of solbuild-config-unstable
Installed solbuild-config-unstable

Initialize Solbuild to ensure its functioning is excellent.

sudo solbuild init

Here are the results:

$ sudo solbuild init

Safety switch forces the installation of following packages:
json-c  openssl-11

Set up Common

Now set up common which is a set of scripts that allows you to easily manage, build, check, and publish packages.

git clone

Results should look like this:

$ git clone
Cloning into 'common'...
remote: Enumerating objects: 1982, done.
remote: Counting objects: 100% (1982/1982), done.
remote: Compressing objects: 100% (1333/1333), done.

Resolving deltas: 100% (1288/1288), done.

Use these commands one after the other to set up symlinks.

ln -sv common/Makefile.common .
ln -sv common/Makefile.toplevel Makefile
ln -sv common/Makefile.iso .

Set up a package

File your name and email address on this command.


git config --global"Mary"
git config --global [email protected]

Set Up a packager file in the home directory.

mkdir -p ~/.solus

Build or Make Packages

Now your system is set for building packages. Let’s build the Zsync package.

Start by making a file for Zsync.

mkdir zsync

Go to the Zsync file.

cd zsync

You will get the Zsync file from their official website. Fetch the Zsync file from the source using this command.


Inside the same folder, build or run this:

echo "include ../Makefile.common" > Makefile

Open the Zsync package file and edit it. In our case, we can remove the Builddeps section in the Zsync .yml file and save it on the save icon.

gedit package.yml

Use the make command to build the Zsync package.

 ~/zsync $ make
make build
make[1]: Entering directory '/home/maryndungu/zsync'
sudo solbuild build package.yml -p unstable-x86_64;

The package will be built successfully.

[Build] install successful

Solus is managed with a lot of eopkg commands. We have covered most of them and those that you will interact with will daily. Also, you can find more commands by using the “eopkg help” command. I hope you have enjoyed the guide which consists of commands you will apply to manage your Solus OS. Note that these commands consist of both long and short-form versions. In case you have any queries, feel free to ask.
