How to install a comic reader
 

Linux was installed by someone else for me, and I have absolutely no idea what I'm doing. I've searched tutorials but they're all gibberish to me.
I'm trying to install a comic reader (comix) that I've downloaded. It would be great if anyone could help.

It will be in your software center in Ubuntu. No need to install comix from the net.

It said "The action would require the installation of packages from not authenticated sources." And to check my internet connection. It's connected. Can I do this manually or is clicking the install button the only way?

That is a standard warning letting you know that comix is not in Ubuntu repositories directly. You should be OK though to

password and hit enter/return key.

then type in after updating is done.

to see version available. To install comix manually

Wow I really have no Idea what I'm doing. Searched variations of sudo apt in the software center and when I tried to install that, it said the same thing it did about comix. "Check connection" then flashed the warning. Nothing I try to install is installing.

Slow down.

You are making things much more complicated than they need to be. Installing software in Linux is far different and ultimate much simpler than installing it in Windows, once you understand how it works.

In Windows, you typically download an executable file (or download and decompress a zip file to reveal an executable file), then run the executable file, which in turn installs the software.

sudo and apt-get are already present on your system. They do not need to be installed.

Here's an explanation of the use of sudo in Ubuntu.

Here's a description of apt-get. Distributions based on Debian use apt-get. Distributions based on Red Hat/Fedora use a program called yum (Yellow Dog Update Manager) to perform the same functions. Distributions based on Slackware--well, Slackware happily goes its own way.

In Linux, executable file installs are rare. I have probably done it with fewer than a dozen programs in seven years of using Linux.

The most common way of installing software in Linux is to install it directly from a repository or repo. When you install from the repo successfully, the installation is complete and, for the most common desktop environments, the application is added to the menu. This article summarizes it nicely for Ubuntu.

The other way to install software is by compiling it. You download the source code and run the necessary commands to create an installable package (./configure followed by make) and then to install it (make install). It's nowhere nearly so complicated as it sounds; this article gives a good description.

Following some of these links and reading up on what's going on will likely help you mightily.

My sources list is blank? I can't uncomment the lineds to enable universe and multiverse.

I imagine you're getting rather frustrated. It looks as if you were cast adrift without being shown how to use the oars. Be assured we will help you; LQ likes nothing more than satisfied Linux users.

Also please post which version of Ubuntu you are running. As Ubuntu has made some significant changes over the past year, that information will help us provide the most useful advice.
