First,download the deb package for Opera Mobile
Open up a terminal window from Applications->Accessories menu and run:
sudo apt-get install ia32-libs
Force to install the deb for i386 on amd64 system
(You need to navigate to the directory where you saved the just downloaded deb package first,in my case it’s
cd Downloads,and then execute following command):
