libwebkit2gtk-4.0-37-gtk2 2.26.2-0ubuntu0.19.04.1 (i386 binary) in ubuntu disco

 This is a transitional dummy package, it can be safely removed.
 .
 WebKitGTK no longer supports plugins that depend on GTK 2. If you
 still need to use the Adobe Flash Player then you can install
 browser-plugin-freshplayer-pepperflash.
