Hmm… I thought I had added the steps for removal.
Anyway… basically, you have to undo all the steps you did here:
Here are the commands… run carefully please:
Remove the popcorn time directory:
sudo rm -rf /opt/popcorntime
Remove the link:
sudo rm /usr/bin/Popcorn-Time
Remove the desktop file:
rm /usr/share/applications/popcorntime.desktop
Remove the catch files:
rm -rf ./.cache/Popcorn-Time
Remove the config files
rm -rf ./.config/Popcorn-Time
This should take care of it.
