Supported Hardware Ubuntu does not impose hardware requirements beyond the requirements of the Linux kernel and the GNU tool-sets. Therefore, any architecture or platform to which the Linux kernel, libc, gcc, etc. have been ported, and for which an Ubuntu port exists, can run Ubuntu. Rather than attempting to describe all the different hardware configurations which are supported for Intel x86, this section contains general information and pointers to where additional information can be found.

Comments and Troubleshooting Install Ubuntu from a USB stick This pages describes how to install Ubuntu by copying the contents of the installation CD to a USB drive (such as a self-contained flash drive or a Memory Stick or SD card reader) and making the USB drive bootable. This is handy for machines like ultra-portable notebooks that do not have a CD drive but can boot from USB media. The main steps are: * Prepare the USB drive * Boot the computer from your USB drive. * Install Ubuntu as you would from a normal boot CD Note: It is highly recommended to use the latest version of Ubuntu to prepare your USB drive. See also the instructions for USB drives from the official Install Guide.

Overview Sun Microsystems have developed Java, which is many things depending on who you ask. It is a language, and an execution environment and probably many more things. On this page Java refers to the software that executes programs compiled to Java byte codes (akin to machine language). Be aware of the Java trap. Although keep in mind that with the GPL licensing of the Sun Java implementation the Java trap is a thing of the past. Even RMS thinks so. Use IcedTea on Ubuntu 7.10 and OpenJDK on Ubuntu 8.04 or later. The first free project to offer substantial parts of Java platform functionality was Guavac. After that the free software movement developed java compilers, most notably the GNU Compiler for Java. GCJ is a front end to the GCC compiler which can natively compile both Java(tm) source and bytecode files. The compiler can also generate class files. Gcjwebplugin is a little web browser plugin to execute Java applets. It is targeted for Mozilla and compatible browsers that support the NPAPI. Others include the Eclipse Java Compiler, which is maintained by the Eclipse Foundation. Eclipse is an open-source Integrated development environment (IDE) written primarily in Java. The Eclipse open source community has over 60 open source projects. OpenJDK is the open source Java, derived from sources which will become OpenJDK 7 in the future.

Running Java under Ubuntu In order to run Java programs and Java applets, you must have a Java environment installed. The GCJ flavor of Java is installed as default, and is usually fine for most purposes. If it is not installed, JavaInstallation describes how to install some opensource flavors of Java. You may, however, have a need to run the Sun flavor of Java if something does not work correctly. To get Sun Java under Ubuntu 7.04 or later running on Intel or PowerPC platform, you should enable the Universe repository in Add/Remove programs, and install either the openjdk-6-jre package or the sun-java6-bin package. (Note: PowerPC version is slow). To get Sun Java under Ubuntu 6.06 or 6.10 running on Intel x86 platform, you should enable the Universe repository in Add/Remove programs, and install the sun-java5-bin package. Note: The same commands will work under Xubuntu/Kubuntu (using Add/Remove or the Adept Package Installer). Choosing the default Java to use Just installing new Java flavours does not change the default Java pointed to by /usr/bin/java. You must explicitly set this: * Open a Terminal window * Run sudo update-java-alternatives -l to see the current configuration and possibilities. * Run sudo update-java-alternatives -s XXXX to set the XXX java version as default. For Sun Java 6 this would be sudo update-java-alternatives -s java-6-sun * Run java -version to ensure that the correct version is being called. You can also use the following command to interactively make the change; * Open a Terminal window * Run sudo update-alternatives --config java * Follow the onscreen prompt

* HowToMD5SUM Contents 1. md5sum 2. MD5SUM on Linux 1. Check the iso file 2. Check the CD 3. MD5SUM on Mac OS X 4. digest(1) on Solaris 5. MD5SUM on Windows 6. MD5SUM on CD 7. MD5SUM of burnt media 8. External Links The program md5sum is designed to verify data integrity using the MD5 (Message-Digest algorithm 5) 128-bit cryptographic hash. MD5 hashes used properly can confirm both file integrity and authenticity. In terms of integrity, an MD5 hash comparison detects changes in files that would cause errors. The possibility of changes (errors) is proportional to the size of the file; the possibility of errors increase as the file becomes larger. It is a very good idea to run an MD5 hash comparison check when you have a file like an operating system install CD that has to be 100% correct. In terms of security, cryptographic hashes such as MD5 allow for authentication of data obtained from insecure mirrors. The MD5 hash must be signed or come from a secure source (an HTTPS page) of an organization you trust. See the MD5SUMS file for the release you're using under http://releases.ubuntu.com (and optionally the PGP signatures in the MD5SUMS.gpg file), or refer to the secure UbuntuHashes page for the official list of Ubuntu MD5 hashes. While security flaws in the MD5 algorithm have been uncovered, MD5 hashes are still useful when you trust the organization that produces them. Moving to more secure hashes like SHA-256 and Whirlpool is under discussion.

Home Face-to-Face Local Support Our worldwide network of Local Community ("LoCo") teams is providing a strong backbone to our already vast and extensive Ubuntu community. Many of these teams provide free, face-to-face local support, such as one-on-one troubleshooting, group sessions, and presentations about Ubuntu. Why not go and see the full list of teams!

Why? "Under Linux there are GUIs (graphical user interfaces), where you can point and click and drag, and hopefully get work done without first reading lots of documentation. The traditional Unix environment is a CLI (command line interface), where you type commands to tell the computer what to do. That is faster and more powerful, but requires finding out what the commands are." -- from man intro(1) For some tasks, especially things like system configuration, it makes sense to use the terminal, and you'll probably have seen instructions on help pages or forums similar to:

Download project files After you've downloaded a file, you can verify its authenticity using its MD5 sum . (How do I verify a download?)

# Download the desired .img file # Install the usb-imagewriter package * If your release does not include this, download it from Oliver's PPA * If imagewriter fails to launch, you may need to install python glade2 support. Install the python-glade2 package or Run sudo apt-get install python-glade2 * If your release does not include it and you are running 9.04 Jaunty Jackalope then run this command from the console: o sudo apt-get install usb-imagewriter # Open Applications -> Accessories -> Image Writer * KDE users will find this in Applications -> Utilities -> Image Writer * on some usb-imagewriter versions (console command: imagewriter) the application fails to write if the image path contains blank spaces, exiting with "IndexError: list index out of range". Also, in case you prefer to launch it from the command line, don't forget to sudo it, otherwise it will give a permission error. # Insert your flash media # Select the downloaded file and flash device, and click "Write to Device" # Remove your device when the operation is complete

Wired troubleshooting If you have a network connection which is not working properly, you can use a few tools to help diagnose what the problem is. Most of the tools in this section require use of the Terminal, which you can open by pressing Applications → Accessories → Terminal. Get information about the current connection ifconfig is intended to allow you to change the settings of your network connections, but it can also be used to list information about the current connection. 1. Press Applications → Accessories → Terminal to open a Terminal 2. Type ifconfig eth1 in the Terminal and press Enter, replacing eth1 with the name of your network interface if it is different. * inet addr gives the current IP address of the connection * HWaddr gives the MAC address of your network device
