Installing jdk8 on ubuntu- unable to locate package update doesn t fix

Question

I ve been trying to install the jdk on my ubuntu after downloading it    first I ve used  sudo apt-get update  then  sudo apt-get install jdk    because I didn t want to write the whole long name    it didn t work- printed the message in the title    I thought the problem might me with the directory I m executing from  I ve executed it from the Downloads directory in which the file exists   so I ve tried executing the same command  sudo apt-get install jdk   from the home directory  root directory   Then it worked   the whole installation took about 5 minutes and it looked like it was installing a lot of things I didn t ask for    I wasn t sure it installed what I needed to I went back to the Downloads directory where the jdk8 package was located and like the first time ran the command from there  the same message as before    couldn t locate the package    What have I done wrong   Obviously it wasn t installed because when I ve checked the version of java  java -version  it didn t show jdk8 was installed    Thank you if you ve taken the time to read to this point

Ubuntu defaults to the OpenJDK packages   If you want to install Oracle s JDK  then you need to visit their download page  and grab the package from there   Once you ve installed the Oracle JDK  you also need to update the following  system defaults will point to OpenJDK    export JAVA HOME  my path to oracle jdk export PATH  JAVA HOME bin  PATH   If you want the Oracle JDK to be the default for your system  you will need to remove the OpenJDK packages  and update your profile environment variables

It s same as vikasdumca s steps  but thought to share the link   run the following command   sudo apt-get install python-software-properties sudo add-apt-repository ppa webupd8team java sudo apt-get update   then   sudo apt-get install oracle-java8-installer   this would install oracle java 8 on ubuntu properly   find it from this post  you can find more info on  Managing Java  or  Setting the  JAVA HOME  environment variable  from the post
