When runnin knime, There is a popup error “knime is unable to display web pages in internal browser”  
In the log I see this:  
!ENTRY org.eclipse.ui.browser 2 0 2021-03-04 09:09:42.283  
!MESSAGE Internal browser is not available: No more handles because there is no underlying browser available.  
Please ensure that WebKit with its GTK 3.x bindings is installed (WebKit2 API level is preferred). Additionally, please note that GTK4 does not currently have Browser support.

Knime version =\> 4.2.2  
OS =\> Ubuntu 16.04 LTS  
libwebkitgtk-3.0-0 is installed.

Please assist.
