java installation

[mulligan]

hi i am trying to install java jre and jdk onto ubuntu. i have had some success with the sudo apt-get install function. however it is now stating.

morgan@morgan-desktop:~$ sudo apr-get install sun-java6-jre
[sudo] password for morgan:
sudo: apr-get: command not found
morgan@morgan-desktop:~$ sudo apt-get install sun-java6-jre
E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
morgan@morgan-desktop:~$

i am not sure if i have java or not can you tell me how to check and how to download properly and also how to fix the problem the above message says i have.

thank you in advance. mulligan.

Run
sudo dpkg --configure -a in a terminal. When the Java license agreement comes up, use Tab to highlight OK then press Enter.

ok i did what you said and then i tried to install java again. this time i got this.

morgan@morgan-desktop:~$ sudo apt-get install sun-java6-jdk sun-java6-jre

You might want to run `apt-get -f install' to correct these:
The following packages have unmet dependencies:
sun-java6-jdk: Depends: sun-java6-bin (= 6-14-0ubuntu1.8.04) but it is not going to be installed
sun-java6-jre: Depends: sun-java6-bin (= 6-14-0ubuntu1.8.04) but it is not going to be installed or
ia32-sun-java6-bin (= 6-14-0ubuntu1.8.04) but it is not installable
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
morgan@morgan-desktop:~$ apt-get -f install
E: Could not open lock file /var/lib/dpkg/lock - open (13 Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?

You need to run

sudo apt-get -f install
In Ubuntu if you see the warnings about not being "root", prefix any suggested commands with sudo. I guess when the package was ported from Debian someone forgot to change the command so that it reads as "sudo apt-get -f install" on Ubuntu based systems.

ok i think i have it now i got it to run and tabed and passed the agreement. do you know how i can check that i have it on my system.

[mulligan]
