Java problems

[dangoeslinux]

Hello, I installed Kubuntu three weeks ago and I am very happy with it. I love the speed of browsing the web compared to what I had before. I am just on dial-up (that's what u get for living too much north) and let me tell you: It's much faster.

Anyways. I encountered some a problem with the Java. I installed the Java plugin through

sudo apt-get install kubuntu-restricted-extras

but something went wrong in the installation. Everything else works (MP3, playing DVDs, etc) but the Java seems not. I remember some error about dependency problems.

If I type "Java" in the console, I get he following:
loslocos@loslocos:~$ java
The program 'java' can be found in the following packages:
* cacao
* j2re1.4
* kaffe
* jamvm
* java-gcj-compat
* gij-4.1
* gij-4.2
* sablevm
Try: sudo apt-get install <selected package>
bash: java: command not found
loslocos@loslocos:~$

I tried to reinstall it using sudo apt-get install sun-java6-plugin but this is what happens:
loslocos@loslocos:~$ sudo apt-get install sun-java6-plugin

hmm. Then I tried purging it (is is installed or not) but this is what I am getting:
sudo dpkg --purge sun-java6-bin
dpkg: dependency problems prevent removal of sun-java6-bin:

The folder /usr/lib/jvm/java-6-sun-1.6.0.03/bin exists, there a bunch of files in there but there is no subdirectory.

Anybody having an idea what I can do to get the Java working? I appreciate your help.

Re: Java problems

I forgot:
Adept Manager shows the following items as installed:
sun-java6-bin
sun-java6-jdk
sun-java6-jre
sun-java6-plugin

Re: Java problems

dpkg --configure --pending
dpkg --audit
at the konsole.

Once you get your package system back in order, look at the directory /usr/lib/jvm.
Inspect the shortcut java-gcj to see where it points.
I had to manually change this shortcut in order to run the correct version of java. I think the shortcuts get messed up when you have 1.4.2 installed and then later go with the newer versions.

Re: Java problems

Hmm. It seems that did not configure the Java properly. Output:

loslocos@loslocos:~$ sudo dpkg --configure --pending

The audit still shows Java half configured:

loslocos@loslocos:~$ dpkg --audit
The following packages have been unpacked but not yet configured.
They must be configured using dpkg --configure or the configure
menu option in dselect for them to work:

The following packages are only half configured, probably due to problems
configuring them the first time. The configuration should be retried using
dpkg --configure <package> or the configure menu option in dselect:

If I try to configure the bin, I get the following:

Re: Java problems

I would try next.

sudo apt-get clean
sudo apt-get update
sudo apt-get upgrade

Hopefully this will clean up the package system and you can try to install java again. If not, then I would try.

dpkg --remove --force-remove-reinstreq "package name"

I am not an expert, so it would be nice to hear from some of the veterans.

Re: Java problems

Thanks. Some of it worked. The sudo apt-get clean did not do much. I did the update and upgrade but the upgrade exited with errors

I removed the packages using your suggested command (dpkg --remove --force-remove-reinstreq "package name") and I was able to remove
sun-java6-plugin
sun-java6-jdk
sun-java6-jre

There are still problems with sun-java6-bin. I was not able to remove it;
