I have a Late 2005 PowerMac G5 and I'm having some trouble
installing Debian on it. I've installed debian on this machine
before but this time I'm hitting some unexpected snags. I
started by downloading the ppc64 iso from
http://cdimage.debian.org/cdimage/ports/current/ppc64/iso-cd/
. I burned it to a DVD and booted it on my G5. When I got to
the page to select a mirror, the installer couldn't connect.
The hostname I used was
deb.debian.org and the directory
was /debian-ports/ . I tried a few different mirrors but none
of them worked. So I decided to try the ppc64 iso from the
2019-11-22 folder instead. That one boots and the installer
connects to the mirror fine, using the same connection info.
The problem is that the installer fails to install grub, and
gives no option to install yaboot! I tried to launch a shell
and install ybin but I couldn't figure it out. I noticed that
bin was downloaded and installed onto the target, but the
installer was trying to use grub.
