Installing packages

I am completely new to ubuntu so sorry if this is a basic question , exactly how do you install software ? I have downloaded the Linux version of Adobe flash player and tried to install it using the apt-get install command in terminal but just get the " unable to find package " message. I have looked on quite a few ubuntu " how to " sites and printed off pages of instructions but none give easy step by step instructions . I also want to install an anti virus and firewall but have the same problem I get the installation icon on my desktop but when I double click on them all I get is a " script " text file . Also when you download a file , how do you know if its a .tar or .deb or .rpm file because when I click on it all I get is an " unknown type " error message. Confused ... I'll say I am ... but willing to give it a try .

you install software (aka packages) by using synaptic package manager in the System-> admin menu. You dont need antivirus or firewall in linux (unless you are very paranoid) install flash by downloading this and double clicking on it and following the instructions: http://mirrors.kernel.org/ubuntu/pool/multiverse/f/flashplugin-nonfree/flashplugin-nonfree_9.0.115.0ubuntu4_i386.deb

I found this extremely helpful when I first started using Ubuntu http://monkeyblog.org/ubuntu/installing/ "How to install anything in Ubuntu"

Thanks to you both am getting the hang of it now Bit strange at first.

there is also a more user friendly version of synaptic in the applications menu under add/remove(it does not have the libraries [libraries are like windows dlls] and it has images for each package.) If you need any help dont be afraid to ask ;)

Don't worry, i think we've all gone through this. Never be afraid to ask, and as i've been told before, no such thing as a stupid question.:D

exactly how do you install software ?Either by using Synaptic Package Manager (the repositories / repos) or the Add/Remove menu (under the Applications menu).

Also when you download a file , how do you know if its a .tar or .deb or .rpm file because when I click on it all I get is an " unknown type " error message.

Confused ... I'll say I am ... but willing to give it a try .Doesn't it say the file extension, like <filename>.<file extension>? If not, then i believe that a simple right-click and Properties will show you the file type.

Oh, and 1 last thing... Welcome to the Ubuntuforums!
