apt update error

[Jan Zumwalt]

When Attempting to update apt, I get the following error.

Code:

E: The repository 'http://repo.linuxliteos.com/linuxlite 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( manpage for repository creation and user configuration details.

I tried the following suggestion without success...

Code:

sudo rm -rf /var/lib/apt/lists/*
