DesktopHTML on Linux

I’m using Ubuntu 20.4 on a Virtual Machine (Mac Intel). The DesktopHTML is not displaying anything. At first my virtual machine had only 1 GB of memory and it was displaying this message.

I assigned 7 GO of ram. I don’t have the message anymore. The progress bar is displayed as a visual feedback when the content is loaded but nothing appears. How to check if WebKit is installed?

UPDATE: it’s working with Linux Mint 19. So what is missing in Unbuntu ?

The HTMLViewer uses libwebkit2gtk .
On both systems run:

sudo apt search libwebkit | grep -i installed

That will show which versions of the libraries are installed. If you run the app from the terminal on Ubuntu do you get any errors in the terminal?

You can check as Adam says. But an error like this is strange on Ubuntu. In my experience Ubuntu should play nice out-of-the-box. This includes a 20.04 LTS ARM version that I just set up.

From your error message, I infer that the HTMLViewer is finding WebKit but the problem occurs thereafter. An absence of WebKit, if you didn’t check first, should throw a catchable HTMLViewerException (with these, I throw the content to the user’s browser.) I am having a similar issue with one particular distro. In my Intel VM farm are two different Gentoos (Gentii? :slight_smile: ), one “stable” and one cutting-edge. On the latter, even with a simple test project, loading WebKit causes the program to simply hang, requiring a force-quit. This seems to be a recent development.

Updated Ubuntu to 22.04 and no issue !
