I am trying for the first time to open downloaded apps, particularly SETI. However, for any app, I always receive this error message: "Nautilus has no installed viewer capable of displaying (file)"

What should I do? Please be specific. I'm a newbie newbie. Thanks for your previous solutions.

First thing to learn:

In Linux YOU DONT JUST DOUBLE CLICK THINGS, THIS IS NOT WINDOWS.

Thats why there are so many viruses in Windows.


There are a few ways to install programs: Compiling from source, installing a package (RPM).

In the case of SETI, I believe its already compiled, just untar that tar.gz, change to the directory, and run the program.

Like:

tar -xvzf seti.tar.gz
cd seti
./setiathome


You have to replace file/folder names with the appropriate ones though.

The first comand untars and uncompresses the file (a .tar is a bunch of files that have been converted into one big file, for storage purposes, and .gz is a compression technique, gzip.

The next one changes to the newly untarred directory.

The last command executes the program.

it is not ziped

tar xvf seti(tab)
