brave – Dissenter Browser no longer launches after Ubuntu 20.04.2 software base update

The effect of the failure is that after updating Ubuntu base software, upon clicking the Dissenter browser’s launcher I do see the browser load temporarily (for no more than a second or two at most) and then disappear altogether without any visible trace.

Dissenter is a free-speech and no-censorship browser built on the Brave browser and developed by the unjustifiably-maligned social media company ‘Gab’.

I might be wrong about this, but I suspect that the recent software base update may have purposely sabotaged my Dissenter installation, similar to the way the Dissenter browser extension was recently removed from the Chrome and Mozilla browser extension catalogs.

Should this be the case, I hope to learn how to circumvent this evil attempt by others to impose upon me what I can and cannot install on my own computer. Otherwise, any advice to get this application to work again would be greatly appreciated.

Here follows my OS version:

~$ cat /etc/os-release
VERSION="20.04.2 LTS (Focal Fossa)"
