• Once you have completed the previous step, the first thing you should do is to check the software updater and click install now. This will ask to reboot the system.
• After rebooting, check if you can access the internet from Ubuntu or not. If not then try changing the network connection from Bridge to NAT.
• Now, the second thing you should check is copy-paste from Windows to Linux.
• Perform the below two commands to update the currently installed packages to the latest version:

  Press CTRL+ALT+T to Launch a Terminal.
  
  $sudo apt-get -y update (immediately update)
  $sudo apt-get -y upgrade (takes some time)
  $sudo apt-get update

  If you get the below error, then it is possible that another installation is still in progress. Please wait till it’s completed or restart your machine.

5. Install Java on Ubuntu:

• Download Java 1.8 from this link
• Copy it to a location (/usr/local/java)

  $sudo mkdir /usr/local/java
  $sudo chmod 777 /usr/local/java
  $ sudo cp ~/Desktop/jdk-8u301-linux-x64.tar.gz /usr/local/java -- (copy file to Java folder)

• Now, extract it using the below commands:

  $ cd /usr/local/java
  $ sudo tar xvzf  jdk-8u301-linux-x64.tar.gz
  $ sudo ln -s  jdk1.8.0_301  jdk  --- (creating alias name)

• Once it is extracted, delete the tar.gz file

  $ sudo rm  jdk-8u301-linux-x64.tar.gz

• Now, edit the system Path file /etc/profile and add the below lines:

  $ sudo vim /etc/profile	(open the file)
  Provide your password.
  #Press esc : $  , Press enter to go to the last line.
  Then press i to get into insert mode and go down
  
  
  JAVA_HOME=/usr/local/java/jdk
  JRE_HOME=$JAVA_HOME/jre
  PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
  export JAVA_HOME
  export JRE_HOME
  export PATH 

• Let your Ubuntu system know the location of Java JDK.

  $sudo update-alternatives --install "/usr/bin/java" "java" "/usr/local/java/jdk/bin/java" 1
  update-alternatives: using /usr/local/java/jdk-14/bin/java to provide /usr/bin/java (java) in auto mode
  $sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/local/java/jdk/bin/javac" 1
  update-alternatives: using /usr/local/java/jdk-14/bin/javac to provide /usr/bin/javac (javac) in auto mode
  

• Let your Ubuntu system know that the above is the default Java JDK

  $sudo update-alternatives --set java /usr/local/java/jdk/bin/java
  $sudo update-alternatives --set javac /usr/local/java/jdk/bin/javac
  

• Now, Reload the etc/profile by using the below command

  $  .   /etc/profile

• Once you refresh/reload the profile check Java is working well or not with the below command

  sumeet@ubuntu:~$ java -version
