WebKitGTK Upgrade
Nuvola Player uses the WebKitGTK web rendering library provided by your system in order to show a user interface of web apps. Unfortunately, distributions don't generally upgrade the WebKitGTK library until the next release of the whole distribution. As a result, web apps may stop working properly with older WebKitGTK libraries and an upgrade is necessary as described in the rest of this page.
Use cross-distribution flatpak builds of Nuvola 3.1, which contains the latest stable version of WebKitGTK+.
The Nuvola Player team provides new WebKitGTK releases in the WebKit for Nuvola Player PPA at Launchpad. To install them, type following commands to a terminal window:
sudo add-apt-repository ppa:nuvola-player-builders/webkit
sudo apt-get update
sudo apt-get dist-upgrade
There is an updated WebKitGTK package for Debian Jessie in the Debian Backports repository. To install it, type following commands to a terminal window as root:
echo 'deb http://ftp.debian.org/debian jessie-backports main' \
>> /etc/apt/sources.list
apt-get update
apt-get install -t jessie-backports libwebkit2gtk-4.0-37
Fedora provides updated WebKitGTK releases as security updates of the webkitgtk4 package.
Arch Linux always ships up-to-date WebKitGTK releases.
