This may mean that the package is missing, has been obsoleted, or
Is only available from another source
E: Package sun-java6-jdk (has no installation candidate)
Said Ubuntu 10.04 has removed the sun-java6-jdk and sun-java6-jre software package
Sudo add-apt-repository "deb http://archive.canonical.com/lucid partner"
Sudo apt-get update
Sudo apt-get install sun-java6-jdk
The error message is the same:

All of these have been done. The source list is also checked .. There is also a http://archive.canonical.com/lucid partner and there are several.

Then, let's learn what the download is ··
JDK
JDK is the core of the entire Java, including the Java Runtime Environment (Java Runtime Envirnment), a bunch of Java tools and the basic Java Class Library (rt. jar ). No matter what Java application server is actually built into a certain version of JDK. the most popular JDK is the JDK released by Sun. in addition to Sun, many companies and organizations have developed their own JDK, such as JDK developed by IBM and Jrocket of BEA, and JDK developed by GNU. Among them, the JVM (Java Virtual Machine) running efficiency of ibm jdk is much higher than that of Sun JDK. The Jrocket running on the x86 platform is much more efficient on the server than Sun JDK. However, we still need to master Sun JDK first.
JDK generally has three versions: SE (J2SE), standard edition, and standard edition. it is a common version of EE (J2EE), enterpsise edtion, and Enterprise edition, this JDK is used to develop J2EE applications, such as ME (J2EE) and micro edtion. it is mainly used for java development tools (JDK) for Java applications on mobile devices and embedded devices) it is the development environment that many Java experts initially use. Although many programmers have used third-party development tools, JDK is still an important tool for Java development. JDK consists of a standard library and a set of Java utilities that are created, tested, and documented. Its core Java API is some predefined class libraries. developers need to use these classes to access Java functions. Java APIs include some important language structures and basic graphics, networks and files I/O. generally, the non-I/O part of Java APIs is the same for all platforms running Java, while the I/O part is only implemented in the general Java environment.
As a JDK utility, there are seven main tools in the tool library.
◆ Javac: Java compiler, which converts Java source code into bytecode.
◆ Java: Java interpreter, which executes Java application byte code directly from class files.
◆ Appletviewer: applet browser, a Java browser that executes Java applets on HTML files.
◆ Javadoc: generate HTML documents based on Java source code and instructions.
◆ Jdb: Java debugger, which can execute programs one by one, set breakpoints and check variables.
◆ Javah: generate the C process that can call the Java process, or create the header file of the C process that can be called by the Java program.
◆ Javap: Java anti-assembler that displays the accessible functions and data in the compilation class file and the meaning of the byte code.
JRE
JRE (Java Runtime Environment, Java Runtime Environment), a set of environments required to run JAVA programs, including JVM standard implementation and Java core class libraries. Is Sun's product, which includes JavaRuntimeEnvironment and JavaPlug-inJavaRuntimeEnvironment (JRE). It is a Java platform that can run, test, and transmit applications on it. It includes Java virtual machine, Java platform core class, and support files. It does not contain development tools-compilers, debuggers, and other tools. JRE needs auxiliary software -- JavaPlug-in -- to run the applet in the browser. j2RE is Java2 Runtime Environment, that is, Java Runtime Environment, sometimes referred to as JRE. if you only need to run a Java program or Applet, download and install it. If you want to develop Java software on your own, download JDK. JRE is included in JDK. note: Because Microsoft does not fully support Java, do not use the virtual machine that comes with IE to run the Applet. Be sure to install a JRE or JDK.
Final implementation method
1. add the source:
Deb http://us.archive.ubuntu.com/ubuntu/ hard multiverse.
2. sudo apt-get update
3. sudo apt-get install sun-java6-jdk
Then the download and installation sun-java6-jdk appears... For a long time, when the download is complete
It indicates the operation is successful. Pai_^
