oracle-java7-installer не се инсталира на PowerBook G4, работещ с Debian

Работя с debian на този по-стар G4 и имам проблем с инсталирането на Java. След търсене в Google намирам проблеми само с други дистрибуции на linux, най-вече ubuntu. Следвах инструкциите тук (които са почти същите като във всички форуми), но все още получавам грешката по-долу. Така че си мисля, че трябва да пропускам нещо друго?
