Problem installing jdk1.1.6

[Gernot Bauer <Gernot.Bauer@jk.uni-linz.ac.at>]

I tried to install jdk1.1.6v4a-3.deb from the slink distribution to my
hamm-system but some errors occured:

mother# dpkg -i /home/gbauer/jdk1.1_1.1.6v4a-3.deb 
(Reading database ... 31523 files and directories currently installed.)
Preparing to replace jdk1.1 1.1.6v4a-3 (using

Unpacking replacement jdk1.1 ...
Setting up jdk1.1 (1.1.6v4a-3) ...
Checking available versions of java, updating links in /etc/alternatives

(You may modify the symlinks there yourself if desired - see `man ln'.)

dpkg: error processing jdk1.1 (--install):
 subprocess post-installation script returned error exit status 2

Could anybody tell me WHAT went wrong?

Thanx, Gernot
