I am using ubuntu 18.04 LTS with Oracle VM virtual box in my Windows 10 system.
After executing this command
sudo apt-get update
I get this error
E: The repository 'http://dl.google.com/linux/chrome/deb 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.
How can I fix the problem?
