I realize it can sometimes be frustrating to learn new things. But I assure you Linux distributions usually handle installing software differently for a reason.
Installing software can damage or compromise systems very easily. Thats why Debain, its derivatives and many other Linux based operating systems use package management systems for software. Its one of the things that makes Debian so secure and stable. Opera and other proprietary applications are not included with the debian packages because it is hard or impossible(often illegal) to redistribute or modify proprietary software. So the Debian community is unable, not necessairily unwilling to provide support for it. If there is some 3rd party software you must use you should ask the providers of that software for help. But I would suggest asking nicely.
