[feisty] update-alternatives doesn't notice java6

[Nicolò Chieffo]

update-alternatives doesn't seem to detect files in sun-java6 packages. (-bin and -jre installed) so no /usr/bin/java

[Áron Sisak (asisak)]

What is the version of Ubuntu are you running? Do you use Feisty or Edgy backports? Please provide an "update-alternatives --list java" output.

For me it works fine, Feisty, x86:

There are 4 alternatives which provide `java'.

  Selection Alternative
-----------------------------------------------
* 1 /usr/lib/jvm/java-1.5.0-sun/jre/bin/java
+ 2 /usr/lib/jvm/java-gcj/jre/bin/java
          3 /usr/bin/gij-wrapper-4.1
          4 /usr/lib/jvm/java-6-sun/jre/bin/java

[Nicolò Chieffo (yelo3)]

I said it worked after a reboot! sorry!

[Áron Sisak (asisak)]

It should work without a reboot, however, it might have been fixed since.
Do you use Edgy or Feisty?

[Nicolò Chieffo (yelo3)]

feisty! mybe a logout could be enough to update some variables...

[Nicolò Chieffo (yelo3)]

Yes a logout was enough. I will reject the bug. Sorry for opening it!

[Áron Sisak (asisak)]

Thanks for reporting it!

[Áron Sisak (asisak)]

Please provide more information if this issue is still present and if a re-login really solves it.

Hello,

This issue is still present. I don't know whether a relogin fixed it, but yesterday I had exactly the same problem (update-alternatives --list did not list java6) and today it worked. I have not done anything requiring superuser rights in the meantime.

What information do you need?

[Pascal De Vuyst (pascal-devuyst)]

Same problem with java6 from Edgy updates.

$ /usr/bin/java
bash: /usr/bin/java: No such file or directory

$ dpkg -l sun-java* | grep ii
ii sun-java6-bin 6-00-0ubuntu1~edgy1 Sun Java(TM) Runtime Environment (JRE) 6
ii sun-java6-jre 6-00-0ubuntu1~edgy1 Sun Java(TM) Runtime Environment (JRE) 6
ii sun-java6-plugin 6-00-0ubuntu1~edgy1 The Java(TM) Plug-in, Java SE 6

$ update-alternatives --list java
/usr/lib/jvm/java-gcj/jre/bin/java
/usr/bin/gij-wrapper-4.1
/usr/lib/jvm/java-6-sun/jre/bin/java

[Pascal De Vuyst (pascal-devuyst)]

I meant Edgy backports instead of updates.

[Bryan Quigley (bryanquigley)]

I have the same problem, and I have logged in rebooted logged out many times.

update-alternatives --list java
/usr/lib/jvm/java-6-sun/jre/bin/java
/usr/bin/gij-wrapper-4.1
bryan@bryan-lin:~$ java
The program 'java' can be found in the following packages:
 * j2re1.4
 * gij-4.1
 * jamvm
 * cacao
 * sablevm
Try: sudo apt-get install <selected package>
Make sure you have the 'universe' component enabled
bash: java: command not found
bryan@bryan-lin:~$

I have: sun-java6-bin sun-java6-fonts sun-java6-jre sun-java6-plugin
installed.

What more information can I provide to help this get fixed? / or is there some magical work around?

[Matthias Klose (doko)]

sudo update-java-alternative --list
sudo update-java-alternative --auto

sudo update-java-alternative --set java-6-sun

[Bryan Quigley (bryanquigley)]

thank you! Got it working by doing the above, btw, it is update-java-alternatives
so...

sudo update-java-alternatives --list
sudo update-java-alternatives --auto

sudo update-java-alternatives --set java-6-sun

I have not been able to reproduce this bug.

[James Cole (intangi)]

What seems to happen is that update-alternatives correctly sets java6 as the default, however the symlink of /usr/bin/java is linked to /etc/alternatives/java which is only handled by update-java-alternatives not the usual update-alternatives.

Is there anyway to make that a bit less confusing or has update-java-alternatives always been the proper way to handle the symlinks for java in /etc/alternatives?

[James Shaw (hertzsprung)]

I've experienced this problem today in dapper. I chose to remove sun-java5-* and install sun-java6-*, and this appeared to complete successfully. However, there is no longer any symlink in /etc/alternatives and so "java" is no longer on the path.

"sudo update-java-alternatives --list" does show java-6-sun 63 /usr/lib/jvm/java-6-sun. A reboot does not fix this problem.

[Áron Sisak (asisak)]

This issue seems to be fixed in Feisty and Gutsy. I am not sure what to do in Dapper.

[Nicolò Chieffo (yelo3)]

works well now

[laga (laga)]

This problem still exists in Gutsy amd64 for me.

I had a lot of different java "flavours" installed (all using packages) and decided to remove them when I was triaging an unrelated bug.

After removing the icedtea-java7* packages and installing the sun-java6* packages, "java" couldn't be executed anylonger because /etc/alternatives/java was pointing to missing files:

rwxrwxrwx 1 root root 40 2008-02-24 13:40 /etc/alternatives/java -> /usr/lib/jvm/java-7-icedtea/jre/bin/java
lrwxrwxrwx 1 root root 37 2007-09-29 14:32 /etc/alternatives/javac -> /usr/lib/jvm/java-1.5.0-sun/bin/javac
lrwxrwxrwx 1 root root 39 2007-09-29 14:32 /etc/alternatives/javadoc -> /usr/lib/jvm/java-1.5.0-sun/bin/javadoc
lrwxrwxrwx 1 root root 37 2007-09-29 14:32 /etc/alternatives/javah -> /usr/lib/jvm/java-1.5.0-sun/bin/javah
lrwxrwxrwx 1 root root 37 2007-09-29 14:32 /etc/alternatives/javap -> /usr/lib/jvm/java-1.5.0-sun/bin/javap

I ran the following lines which I found in this ticket:
sudo update-java-alternatives --list
sudo update-java-alternatives --auto

and that fixed it.

It'd be very nice, though, if this was working out of the box.

[Bryan Quigley (bryanquigley)]

Is anyone still getting this bug? Gutsy and Feisty are both unsupported now.

[Nicolò Chieffo (yelo3)]

not getting it in current versions
