Summer time …It’s time to keep my YunoHost server efficient,
I remove old kernels, orphaned packages, and leftover config files. This frees up disk space and helps maintain system stability and performance.
C’est l’été, j’ai profité de faire un bon nettoyage de l’ensemble de mon instance Yunohost. après plus de 12 ans d’usage et reinstalles complètes quelques anciens kernel et anciens parametres d’Apps… cela rend le système plus stable et tout frais.
Voici un script complet après diverses sources sur le net. ( Script passé sur IA)

How to use:
1/ Create the script file on your server:
nano yunohost-cleanup.sh
2/ Paste the code above, save and exit.
crtl O , Enter , crtl X
3/ Make it executable:
chmod +x yunohost-cleanup.sh
4/ Run the cleanup:
sudo ./yunohost-cleanup.sh
NB: 
Use with caution:
This will delete all Node.js dependencies (node_modules directories) from every app located in /var/www.
Peertube, Nextcloud plugins, SearxNG, etc.
It is safe only if the apps have been uninstalled, or if you plan to reinstall or rebuild their dependencies.
