I am trying to install opera browser from the terminal. I downloaded the 'debian' installer because it didn't show up in software center.

It completely destroyed my software center - it is frozen and I have no idea how to fix (I have a different thread for that though).

Can I use this thing called synaptic package manager to install Opera? or am I stuck with Firefox?

How do I install Opera Browser?

You have asked a lot of questions here. In future can you limit your questions to one topic for each question. It makes it easier for us to answer (and more questions means more chances to earn reputation. Also questions are easier to read if you use correct capitalisation and puctuation. –  Warren Hill May 5 '13 at 12:55
    
To pick up on some of the questions Opera is being dealt with as answers but Ubuntu Commands, sudo, synaptic. If you these sites do not cover what you need to know ask a separate question about each. –  Warren Hill May 5 '13 at 13:00

Synaptic is a graphical interface for Aptitude, the package manager in Ubuntu/Linux. It provides a listing of available software packages that are available to download and install from the repositories listed in your Software Sources. Synaptic is less intimidating to use than apt-get in a Terminal interface for users not used to dealing with the command line.

Preceding commands in Terminal/command line with sudo imparts a restricted root-user ability for performing commands that are not available for standard user accounts.

When in doubt about any basic command in Terminal, you can always man [base command] to access the command manual pages. man sudo will show the manual for sudo, for example. There is also extensive documentation on the Ubuntu website for most commands.

As for installing Opera, it is not maintained in the standard Ubuntu repositories. You have two options:

1) add the Opera repository to your Software Sources as mentioned in the other answer and following the directions in the provided link; or

2) download and install Opera manually.

To install Opera manually, go to the Opera website (www.opera.com) and download it from there. Presuming that you have your downloads set to go to your Downloads Folder, you can run the following in Terminal:

cd /home/your_account/Downloads ;ls -l Replace "your_account" with your short name; the "ls -l" will list the contents of the Downloads folder. Locate the Opera package file - it should be something like 'Opera_12.15.1748_amd64.deb'.

sudo dpkg -i Opera_12.15.1748_amd64.deb and enter your password when prompted. This will run the Opera installer.

In order to have Opera updated automatically, you should still add the Opera repository to your list of software sources.

Thanks douggro. I downloaded it and double clicked on it like it was an .msi yesterday.. It blew up software center, update mgr, and synaptic. I will try your method. –  bruce May 5 '13 at 14:22
