package tomcat5.5-admin 5.5.20-5ubuntu2 failed to install/upgrade: el subproceso post-installation script devolvió el código de salida de error 255

Binary package hint: tomcat5.5

I have a clean Gutsy Tribe 4 installation. I installed Sun JDK 6, Eclipse, Mysql 5 without errors.
Then, I tried install tomcat5.5, tomcat5.5-admin, tomcat5.5-webapps packages. Synaptic could install these packs and theirs dependences. But, finishing, I received a message error about tomcat5.5-admin.

Finally, I just reinstalled tomcat5.5-admin without problems.
