I have bad news for you. Lubuntu 14.10 PPC wasn't released last week.

Due to several bugs, including a showstopper for those with Radeon graphics (1377878), there will be no ppc release for this version. We recommend using one of the LTS versions.
This bug doesn't affect our Sam440ep (Flex), Sam460ex (Lite), and AMIGA one X1000 computers. They haven't got this bug. The AMIGA one X1000 has even 3D acceleration with the unofficial Mesa package for Lubuntu 14.10 PowerPC (MesaLib-1.0.0.4-Lubuntu_14.10-powerpc-test.tar.bz2).
The AMIGA one X1000 is the only computer which supports Lubuntu 14.10 completely.
