Hi sla-sz, maybe I'm doing this wrong, but I logged into su on terminal and then put:
sudo sh install-opera.sh opera-stable_35.0.2066.10_amd64.deb
And it's not detecting the file although it's in my downloads folder. What am I doing wrong? I'm sorry, I'm really rusty and I'm at terminal completely confused. I feel like I'm missing a step or few.
