my copy of Vivaldi seems to be terminally broken but everything i have tried to remove doesn't work. after using the scudo purge it is still in my start menu and it stills boots up in a broken state
what do i do to remove completely and try a fresh install
Ok i got it fixed I just need to remove vivaldi and clear the local cache.
That removes the package, and your personal stored config and cache of the browser. NOTE: rm -rf is permanent without a backup or snapshot to restore from. Don't delete these unless you are certain you want to.
Install Synaptic and remove it from there. I have used Vivaldi on KDE Neon in the past and I remove it using Synaptic, although you can also remove it from Discover.
