Cannot set Chrome as Default Browser - Lubuntu 20.04
Solution 1:
This answer is just Gabriel's found on the Lubuntu discourse site
Configuring
x-www-browser
in Alternatives, XDG'sdefault-web-browser
and Lubuntu's default internet browser application in Session Settings is not enough. Turns out Chrome looks at/etc/xdg/xdg-Lubuntu/mimeapps.list
and you have to edit it as sudo and replace the instances of the "firefox" string with your browser of choice.Hope I've been of some help.
