I made a fresh install of KUbuntu 18.04 and now when I try to update packages using sudo apt-get update
I get the following error
E: The repository 'http://ppa.launchpad.net/docky-core/stable/ubuntu bionic Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
sudo apt update
,sudo apt full-upgrade
, andsudo apt install latte-dock
in that order. – DK Bose Jul 30 '18 at 09:05
