As in this example, my current installed version is 9.5.12.

Step 2 – Backup

Before we begin, ensure you have backup all your essential data, including the GLPI database and relevant files. This will ensure the safety of your data during the upgrade process and provide the ability to restore it in case of any issues.

Throughout this guide, assume the following:

  • GLPI’s database name: glpi_db
  • GLPI’s database user: glpi_user
  • GLPI’s database password: glpi_PWD
  • GLPI’s installation directory: /var/www/html/glpi

Please make sure to replace these values with your actual database name and installation directory when following the instructions.

Backup Database

Open the Terminal and execute the following command to back up the GLPI database to the /home/username/ directory with the name glpi-database.sql

sudo mysqldump -uroot -p glpi_db > /home/hg/glpi-database.sql

And run the following command to ensure that you have successfully backed up:

ll /home/hg/


Backup the root directory of GLPI

Go to the /var/www/html directory

cd /var/www/html


Execute the following command to back up the root directory of GLPI:

sudo mv glpi glpi_backup_9.5.12



Step 3 – Download the Latest version of the GLPI

Go to the official website here and obtain the link to download the latest stable version of GLPI as shown below:


Execute the following command to download it:

sudo wget -O glpi.tgz Paste_link_to_here

Extract the downloaded file

sudo tar -xvf glpi.tgz


Next, change the permissions and ownership of the extracted GLPI directory. You can use the following commands:

sudo chown -R www-data:www-data glpi

sudo chmod -R 755 glpi



And restart the Apache service to apply the changes:

sudo systemctl restart apache2
