Sorry, i dont understand you language, but have same erros.
Solution probably not clean, but package install is possible.
Download package pandorafms-agent-unix_3.1_all and then:
mkdir -p extract/DEBIAN
dpkg-deb -x pandorafms-agent-unix_3.1_all.deb extract/
dpkg-deb -e pandorafms-agent-unix_3.1_all.deb extract/DEBIAN
rm extract/DEBIAN/md5sums
Remove line: /etc/pandora/plugins from
extract/DEBIAN/conffiles
mkdir build
dpkg-deb -b extract/ build/
cd build
dpkg -i pandorafms-agent-unix_3.1_all.deb
DONE!
