Look like an old instruction. Because here is the result:

\W: GPG error: https://deb.opera.com/opera… stable InRelease: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY D615560BA5C7FF72
E: The repository ‘https://deb.opera.com/opera… stable InRelease’ is not signed.
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.

Hi Sergey,

Thank you for your input! There are no old instructions but rather incorrect command order. Try:

$ wget -qO- https://deb.opera.com/archi... | sudo apt-key add -
$ sudo add-apt-repository "deb [arch=i386,amd64] https://deb.opera.com/opera... stable non-free"
$ sudo apt install opera-stable

Thank you for pointing this out. The article will be updated shortly.
