I recently installed Linux Cinnamon 18.2 Sonya and tested the Yandex and Vivaldi browsers. I did not like and uninstalled these two browsers, however when I give the command:
sudo apt-get update
It appears in the terminal:
Ign:7 http://repo.vivaldi.com/stable/deb stable InRelease
Obter:8 http://repo.yandex.ru/yandex-browser/deb beta InRelease [4.322 B]
Atingido:9 http://repo.vivaldi.com/stable/deb stable Release
If I have already uninstalled these two browsers, why do these links appear?
