Ubuntu - Apache - sudo - command not found

[Bartbart]

Hi guys,

First of all, I'm a total newbie. I've done some research however I couldn't find the answer. Maybe because I don't understand it well enough.
What I'm trying to do is to install Apache server on Ubuntu. I've tried to follow the step-by-step guide and I already have a problem right at the very beginning.

Please have a look at the screenshot.

Any idea how to fix that "command not found" error ?

Thanks in advance

If the glimmer of text I see in the upper left is correct, that's because you're not using Ubuntu (or any distro that uses apt). You're using OpenSUSE.

Refresh OpenSUSE repository from the Internet, execute:

sudo zypper refresh

Upgrade OpenSUSE Linux, type:

sudo zypper update

zypper is the OpenSuse equivalent to apt in Ubuntu/Debian
