Public bug reported:

Binary package hint: ca-certificates-java

Description:    Ubuntu 10.04.2 LTS
Release:        10.04

ca-certificates-java:
  Installed: 20100406ubuntu1
  Candidate: 20100406ubuntu1
  Version table:
 *** 20100406ubuntu1 0
        990 http://archive.ubuntu.com/ubuntu/ lucid/main Packages

Here at the Sanger Institute we have our own local CA.  We distribute the 
certificate for that CA to all of our machines using cfengine.  This works fine 
with the regular ca-certificates stuff on both Debian and Ubuntu.  But it fails 
with ca-certificates-java, as follows:

The keytool invocation in the postinst script which attempts to add the
certificate fails, and the error is discarded, so it's not immediately
obvious what went wrong.

I edited the postinst script to include set -x so that I could get
something out of it, and noticed (1) that the init script deletes the
temporary output file even if the script fails, which means that you
can't see the errors. So, I changed it so that it doesn't delete the
tempfile if there are errors, and this then showed me that the following
part of the script execution path shows the error being generated:

+ LANG=C
+ LC_ALL=C
+ keytool -importcert -trustcacerts -keystore /etc/ssl/certs/java/cacerts 
-providerClass sun.security.pkcs11.SunPKCS11 -providerArg 
'${java.home}/lib/security/nss.cfg' -noprompt -storepass changeit -alias 
genome_research_ltd_certificate_authority_cert_pem -file 
/usr/share/ca-certificates/sanger.ac.uk/Genome_Research_Ltd_Certificate_Authority-cert.pem
+ grep -q 'Signature not available' /tmp/fileW2Zx2A
+ echo ' error adding 
sanger.ac.uk/Genome_Research_Ltd_Certificate_Authority-cert.pem'
  error adding sanger.ac.uk/Genome_Research_Ltd_Certificate_Authority-cert.pem
++ expr 0 + 1
+ errors=1

and the log entry says:

keytool error: java.security.ProviderException: Secmod module already
configured

Google doesn't have much to say about this particular error. This is
causing us serious issues, since it's causing dpkg and aptitude to fall
over on most machines, perpetually trying to run the ca-certificates-
java postinst script.

Hopefully you know what that error means...
