Opera is not present in the default Ubuntu repositories, however it is available by ppa. Open a terminal and run the following commands:
wget -O - http://deb.opera.com/archive.key | sudo apt-key add -
sudo sh -c 'echo "deb http://deb.opera.com/opera/ stable non-free" >> /etc/apt/sources.list.d/opera.list'
sudo apt-get update
sudo apt-get install opera
The wget failed out on several systems I had, just had to separate those into single wget, then single apt-key and it worked just fine.
