I got tired of manually updating Element Web to the newest version so I made a simple script to do most of the work for me.
All you have to provide is the new version of element-web and confirm that the signature is correct. Everything else is handled by the script.
The script should be called from the directory where element-web is currently installed so that the files are downloaded to the correct location. The script assumes www-data owns the directory and that the files are located in /var/www/element.site (change to your own custom directory). The script also copies config.json and welcome.html to the new version directory as I have made changes to them that I’d like to keep. My setup of nginx uses /var/www/element for Element Web which is why the link is created.
Not a work of art, but it works : )
