Blender: InstallingUbuntu

Installing Blender on Ubuntu

Software name : Blender
Homepage : http://www.blender.org/
Software version used for this installation : 2.4.3
Operating System use for this installation : Ubuntu 7.04
Recommended Hardware : 300 Mhz processor (CPU) minimum, internet connection

If you are used to an Operating System like Windows or MacOSX­ you may have installed software by downloading it from a website and double clicking on the downloaded file, and clicking through all the licence agreements, configuration options etc. This is the 'old' way of installing software. The 'new' way is much smarter - you choose what you want to install from a list and press 'go'. The rest - finding the files, downloading the files, installing software, is taken care of by Ubuntu itself while you go and get a cup of tea or work on something else. It can't get much easier. 

However, new ways take a little getting used to, and so we will first look at the basic tool needed to install software this way, and then how to use it to install Blender.

Synaptic Package Manager

The Synaptic Package Manager (SPM) is used for more than just installing software. It can also upgrade your entire operating system, and manage all software installed on your computer. However most people use SPM for just installing new software. Before you embark on this process, there are a few concepts that you may wish to get familiar with. It's not crucial you understand them thoroughly, so just read the explanations and then let it soak in over time. The ideas behind SPM will become clearer with use.

What is a repository?

SPM can automate the installation of software on your computer because it has a direct connection to one or more online software repositories. These repositories are vast archives of programs that have been pre-configured for installation on your operating system. When your computer is online, SPM can connect to these archives, check what software is available for installation, and present you with a list of installable software. All you have to do is select the software from the list that you want. SPM then downloads the software from the repository and takes care of the installation process.

So SPM is actually a repository manager: it manages which repositories (there are many) you wish to access, and which programs to download and install from those repositories.

SPM allows you to choose which repositories it accesses through its settings. The default repositories used by Ubuntu can be extended through the SPM settings so you can access a wider range of programs. Ubuntu calls each repository by a simple name. They are: Main, Universe, Multiverse, Restricted. By default Ubuntu only uses the Main online repository. If you wish to access you the other repositories, you must do this by changing repository settings of SPM.

What is a package?

When SPM downloads a programs for installation, it is in the form known as a 'package'. This means that it is a compressed archive of the program, pre-configured so that it can install nicely on your computer. If the package has been configured nicely (and the Ubuntu project team spends a lot of time making sure this is the case), then many of the headaches that installing software can bring are taken away — it's the aspirin of software installation. One of the biggest issues with installing software on any form of Linux (Ubuntu is one of many types of Linux), is dependencies. Dependencies are all the other packages required by a particular package. If, for example, I want to install an audio editor, that audio editor software may use some functionality of other programs to do its job.

SPM takes the (often) dark art of dependencies away from you, and manages this itself. So if you wish to install a program and it has dependencies (and the list can be long), you don't have to work this out yourself. SPM knows already what is needed, finds it, and installs it along with the software you have chosen.

So, SPM, as well as managing which repositories you access, is also a package management software. Hence the name: Synaptic Package Manager.

apt

You don't really need to know about 'apt', so if you are on the verge of being confused then don't read this short section. If you are a geek wannabe, then read on.

Ubuntu is a form of Linux that has derived from another form of Linux called Debian. This family of Linux has in common (amongst other things) the package/repository management system. Both Ubuntu and Debian use the apt system for managing packages. APT is an acronym for Advanced Package Tool.

SPM is actually a 'front end' (graphical interface) for controlling 'apt'. So SPM is the nice user interface that you see, but the real work is done by 'apt'. There are other ways of managing 'apt', such as the command line interface known as apt-get. In the world of Linux, there are many varieties of Linux users and they have their own ways of doing things. In general it's safe to say most Debian users use apt-get, and most Ubuntu users are happier using SPM.

Configuring Synaptic Package Manager

To install most software on Ubuntu, you need to change the default repository settings of SPM, because many programs are not contained in the default repository. To do this, you need to open the Synaptic Package Manager, which you can do via the System menu. If you haven't changed the default Desktop of Ubuntu, then the System menu can be accessed at the top left of your screen:

If all is good, you are prompted for a password.

pass.jpg

Here you must enter your password (the same one you use to log into the system). If you don't know the password, then you have a problem and it's probably caused by the fact that the computer you are using is not yours. In this case you have to find the computer's owners and ask them for the password (which is usually not polite unless you know them well) or ask them to input the password while you look casually in the other direction.

Assuming the password entered is correct, you now see the SPM open in front of you. It may be that you first see the following 'Quick Introduction' (which appears if you haven't used SPM before).

splash.jpg

Just click Close and move on.

Let's look at the Synaptic Package Manager interface.

spm1_1.jpg

Let's not worry about the details of the interface for now. All we want to do is change the repository settings. To do this, on the Settings menu, click Repositories.

Now we get to where we can do some business. Make sure that all the options are selected:

repositories2
 

Now close that window by clicking the big Close button at the bottom right.

close.jpg

Next, you see a warning telling you the repository has changed:

repositorychanged.jpg

Click the Close button.

Back in the SPM interface, you need to refresh the repositories as the warning suggests. To do this, click Reload:

You then see a status window saying the repositories are being updated and showing the progress.

Installing Blender with Synaptic Package Manager

Now the real business. It's pretty easy. Click on the nice big Search button:

search.jpg

The search window will open and now enter 'blender' in the field:

syn_search

Great. Now press Search at the bottom right of the above window. The search should not take very long and when it is complete you will see Blender listed :

blender_pkg 

If you highlight Blender (by clicking once on the name) you will see some information about Blender displayed :

info

Now you can read the information if you wish but there is nothing critical there. Best thing to do is just to double-click on blender. By doing this you are 'marking' (choosing) the software for installation. If you do so then an additional window appears:

mark 

Now click Mark:

mark2.jpg

You have now told Synaptic Package Manager that you want to install Blender. If all is well then the package will be highlighted:

selected

Now press the Apply button with the nice big tick next to it :

apply1.jpg

Next SPM informs you of how much space will be taken by the installation :

apply_1.jpg

Now you can just click Apply at the bottom right of the screen and the installation will start. A progress bar will be shown:

downloading.jpg

When it is completed (downloading and installing) you will have this screen : 

applied.jpg

That means all is well. Pat yourself on the back and press Close. Synaptic Package Manager will then return to its original state. Close it :

quit.jpg

Now you can open audacity...just browse to the Applications menu, choose Graphics, select Blender and release the mouse :

open

If all is well you will see Blender:

running_1

Congrats!

Trouble?

If you did not see Blender open and nothing happened then it might be that you need to enable the right video drivers for your computer. Blender needs to have extra support for running your monitor or screen so it relies on small pieces of software ('drivers') that assist it with these processes. To check you have the right drivers operating first click on 'System' and then 'Administration', then 'Restricted Drivers Manager' :

trouble1

Now you will be asked for a password. Use the password you used to log into the computer (or the 'superuser' or 'root' password if you know it), then you will see a window like this :

trouble2png

The information contained in your window may not match the above exactly as the driver listed will depend on what hardware you have installed.

Now double click on the 'enabled' check box and you should see this warning :

trouble3png

Click on 'Enable Driver' and an installation process will proceed, ending with the following screen :

trouble4png

If you hit 'Close' you will see this :

trouble5png_1

Now you need to restart your computer. Then try and open Blender again using the method described above.
