Update & Upgrade Linux Mint

First, update your system to ensure all existing packages are up to date to avoid conflicts.

sudo apt update && sudo apt upgrade

Install FreeOffice

The first and easiest method is to install FreeOffice using the source APT repository. This version is often up-to-date, but if you prefer working with the latest versions, then using the Flatpak or Snapcraft version would be best.

First, install the required packages.

sudo apt install dirmngr ca-certificates software-properties-common gnupg gnupg2 apt-transport-https curl -y

Next, import the GPG key required to verify the authenticity of the packages as follows.

curl -fsSL | gpg --dearmor | sudo tee /usr/share/keyrings/softmaker.gpg > /dev/null

Now import the APT repository using the following command.

sudo sh -c "echo 'deb [signed-by=/usr/share/keyrings/softmaker.gpg] stable non-free' > /etc/apt/sources.list.d/softmaker.list"

Run a quick APT update to reflect the newly added APT source.

sudo apt update

Lastly, install FreeOffice using the following command.

sudo apt install softmaker-freeoffice-2021 -y

How to Launch FreeOffice

Now, the best method to launch FreeOffice is using the application icon.

Taskbar > Office > FreeOffice {Text Maker, Presentations, PlanMaker}


Alternatively, you may want to use it for applications quite frequently. Right-click the icon and add it to favorites, making the icons appear on the taskbar.

The first time you open any FreeOffice applications, you will be prompted to select a theme. This user choice has multiple light and dark theme options with icons.


Once configured, you can proceed to use the FreeOffice version of the application you launched; they would look similar to the one below.

Example FreeOffice Text Maker:

Example FreeOffice Presentations:

How to Update/Upgrade FreeOffice

Next are the commands to run in your terminal to check for updates. These commands will blanket check all installed packages on your system that match the installation package manager. Ideally, you should run this regardless, even if auto-updates are set up to ensure your system is up-to-date and no update errors occur for newer users.

sudo apt update && sudo apt upgrade

How to Remove (Uninstall) FreeOffice

First, remove the office suite using the following command for users that no longer wish to have FreeOffice installed.

sudo apt autoremove softmaker-freeoffice-2021 --purge -y

Users that will no longer require the APT import repository since you will not use it again can safely remove it, which is good housekeeping and security best practices.

sudo rm /etc/apt/sources.list.d/softmaker.list

Optionally, you can remove the GPG as well with the following command.

sudo rm /usr/share/keyrings/softmaker.gpg
