I am pleased to bring the Webmin app for the Yunohost back to life.
Webmin is a web-based interface for system administration for Unix. Using any modern web browser, you can setup user accounts , DNS , file sharing and much more. Webmin removes the need to manually edit Unix configuration files like /etc/passwd , and lets you manage a system from the console or remotely .
Install the app by web-admin interface or by this command:
$ yunohost app install https://github.com/YunoHost-Apps/webmin_ynh
Note: This app has root access which can change core things in the system, thus breaking the YunoHost . Use it carefully and read the documets two times before chaning values.
