The Opera team offers snap package (containerised software package), which is always up-to-date (auto-updates itself). And you can simply install it in Ubuntu Software:

Also traditional Opera binary package for Ubuntu is available for download at the link below:

You can make Software Updater receive future updates for the traditional Opera package by adding its official apt repository:

1. Open terminal (Ctrl+Alt+T) and run command to add the opera repository:

sudo sh -c 'echo "deb http://deb.opera.com/opera-stable/ stable non-free" >> /etc/apt/sources.list.d/opera.list'

2. Get the key:

wget -O - http://deb.opera.com/archive.key | sudo apt-key add -

Finally either install Opera via following command or upgrade the browser via Software Updater:

sudo apt update

sudo apt install opera-stable

Uninstall:

For the Opera snap package, simply remove it from Ubuntu Software.

For the Opera apt repository, launch Software & Updates and navigate to Other Software tab.

To remove traditional opera package, either use your system package manager or run command in terminal:

sudo apt remove --autoremove opera
