In reply to Anton.

@Anton,

Corrected the command in the article, as pointed by you.

Yes, no need for sudo in front of echo…

You forget a / here, it must be /etc.
$ echo “deb http://ppa.launchpad.net/linuxuprising/java/ubuntu bionic main” | sudo tee etc/apt/sources.list.d/linuxuprising-java.list

The correct command is:

$ echo "deb http://ppa.launchpad.net/linuxuprising/java/ubuntu bionic main" | sudo tee /etc/apt/sources.list.d/linuxuprising-java.list

and it needs a sudo in front of the echo?

Do you try the commands before publishing?
