Installing Azureus on UbuntuSoftware name : Azureus
The easiest way to install software on Ubuntu is to use the software known as the Synaptic Package Manager. Lets look at how to set it up and use it to install Azureus.
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. Its not crucial you understand them throughly, so just read the explanations and then let it soak in over time. The ideas behind SPM will become clearer with use.
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 softwares 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 softwares 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 softwares. 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.
When SPM downloads a software for installation it is in the form known as a 'package'. This means that it is a compressed archive of the software, pre-configured so that it will install nicely on your computer. If the package has been configured nicely, and Ubuntu spends a lot of time making sure this is the case, then many of the headaches that installing software can bring are taken away - its the panadol of software installation. One of the biggest issues with installing software on any form of Linux (Ubuntu is one of many types of Linux), are dependencies. Dependencies are all the other softwares required by a particular software. If, for example, I want to install a audio editor, that audio editor software may use some functionality of other softwares 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 software 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.
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 - 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 actually an acronym short 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 also, 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 its safe to say most Debian users use apt-get, and most Ubuntu users are happier using SPM.
To install most software on Ubuntu you will need to change the default repository settings of SPM as many softwares are not contained in the default repository. To do this you will need to open the Synaptic Package Manager and you can do this 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 will be prompted for a password.
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 its probably caused by the fact that the computer you are using is not yours. In this case you have to find the computers owner 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 will now see the SPM open infront of you. It may be that you first see the following 'Quick Introduction' (this appears if you haven't used SPM before).
Just click Close and move on. Lets look at the Synaptic Package Manager interface...
Lets not worry about the details of the interface for now. All we want to do is change the repository settings. To do this click on the Settings and choose Repositories
Now we get to where we can do some business. Make sure that all the options are checked :
Now close that window by pressing the big close button at the bottom right.
Next, you will see a warning telling you the repository has changed :
Click the Close button and move on to SPM so you can refresh the repositories as the warning suggests. To do this, do as the warning says - click on Reload :
You should then get some feedback saying the repositories are being updated and showing the progress.
Search for AzureusNow press the "Search" button on Synaptic :
You will see a small pop up :
Now type 'Azureus' in the "Search" field :
Then press "Search" and Synaptic will start searching for the installation file. When it has completed you will see something like this :
Now we want to 'mark' the software we wish to install. In this case we right-click on 'Azureus' and you will see "Mark for Installation" appear:
Select this option and left-click on the mouse. You will see a pop-up asking you to confirm your choice :
You will see here a lot of software listed for installation that you did not choose. This is because Synaptic automatically works out what other software is needed for Azureus to work and installs that as well. So, the only thing to do here is confirm you want to move ahead with the installation and press "Mark". This will return you to the following:
You will notice the icon next to "azureus" has changed. This shows the software is correctly marked for installation. Now click on "Apply" :
Now the installation process is about to really start. Just one more confirmation window:
Click "Apply" and the software will be installed. You will see a few progress windows:
Just wait until its all done. Then you should see this :
This means the software is installed. You can now press "Close" and you may also wish to quit Synaptic. Open AzureusUbuntu has nicely installed Azureus for you and placed some shortcuts in the "Applications" menu for you to use to open the software. To do this click on "Applications" and browse down to "Internet" and you will see Azureus listed:
When you select Azureus a few windows might appear asking you if you wish to update Azureus :
Click "Update" and the update will be automatically downloaded and installed, finishing wiht a window like this : Press "Close" and then you will see another configuration window asking you which language you wish to use:
Select your preferred language. Mine is English so I highlight this and press Next > and the following will appear : Now you have a real choice. If you only want to use Azureus to download files then keep the setting on "Beginner". If you wish to also share your own files then you may choose to select "Intermediate". The "Advanced" setting is for those that already know a lot about BitTorrent and networks. Its advised you select "Beginner", which is the default (you can always change the setting at a later time). Press Next > On the next screen you will see this :
Here you can tell Azureus how fast your internet connection is. If you know how fast your connection is then choose the right entry from the drop-down menu :
Don't worry about the terms "adsl" and "cable" these describe specific internet connection technologies. Choose the speed listed which is closest to your connection speed (if you know it). If you are connected via a Modem (telephone) then choose "Modem". If you do not know your connection speed then don't worry about it, just leave it as is. The other options ("Max Active" etc) will change according to the setting you choose in the drop down box. These are the Azureus 'optimum' settings which are automatically set. They determine the number of downloads and uploads your installation will deal with at any one time.
Press Next > :
The above screen will look like alien speak if you don't know anything about how routers and the internet work. You may not even know what a 'router' is. If you don't know, then don't be concerned. You have one way to find out if you need to change this setting. Press the "Test" button. If you get something like "NAT Error" as a message then you have a problem. Azureus may not work in this situation. Try it first and if you find you cannot download files then you probably have to get someone to help you work through this. Otherwise press Next > :
This setting is where Azureus will save the files you download. You are strongly recommended to change this. This is because Azureus stores your downloads by default in a directory you will not be able to find easily if you have little experience with Ubuntu. This is a directory folder with a name that begins with a '.' (dot) and that means that folder is normally 'hidden' or invisible. You should click the "Browse" button and choose another directory that you kow you can find easily. When you have done this press "Finish" and you will see the following:
Press "Close" and Azureus should open.
