keytool error: java.lang.ClassNotFoundException: org.bouncycastle.jce.provider.BouncyCastleProvider

Dude nothing to worry , I solved the same error, please concentrate on JAVA paths

install java -6-openjdk

find out right java path first
Find outjava(executable) in  in this path it is there or not
$/usr/lib/jvm/java-6-openjdk/jre/bin
if is there then do
Now java home will become

export JAVA_HOME=/usr/lib/jvm/java-6-openjdk/jre

PATH will become

export PATH=$PATH:$JAVA_HOME/bin

or

export PATH=$PATH:/usr/lib/jvm/java-6-openjdk/jre/bin

In this path /usr/lib/jvm/java-6-openjdk/jre/bin  u can find out keytool(executable) that means you are pointing to correct location
now run

command is correct

$ keytool -keystore /home/moto/cacerts.bks -storetype BKS -provider org.bouncycastle.jce.provider.BouncyCastleProvider -storepass changeit -list -v

I got the output
