I tried an installation of the new image "debian-10.0-ppc64-NETINST-1.iso" from [1] on a PowerMac G5. The image was copied with "dd" on a usb stick and then loaded with on Open Firmware by using:
boot ud:,\install\yaboot I did an "expert mode" installation and loaded the following modules: hfs, network-console, fdisk, parted. Fan were spinning loudly but I can confirm that the following command stops them: # modprobe -v windfarm_core The partitioning step was not working so I edited file "/lib/partman/init.d/26zfs-devices" changing line 19 from "local zfs_load_timeout" to "zfs_load_timeout". At this point the partitioning step started. I created a new "mac" partition on the hard drive. I tried manual partitioning but was not able to find a way to create a new "bootstrap" partition. I remember there was an option for it in the past, now I can not find this option for a new partition anymore. So I used automatic partitioning of the whole drive, which gave me this layout: SCSI4 (0,0,0) (sdc) - 163.9 GB ATA Maxtor 6L160M0 #1 32.3 kB Apple #2 20.0 MB B K untitled #3 160.4 GB f ext4 untitled / #4 3.6 GB f swap swap swap 512.0 B FREE SPACE I felt like something was missing but I continued the installation anyway. Base system was installed fine. As repository I used the usual [2]. Used a minimal software selection (default only). Grub installation failed with the following message: "An installation step failed. You can try to run the failing item again from the menu, or skip it and choose something else. The failing step is: Install the GRUB boot loader on a hard disk" On the log screen I see: Apr 7 08:05:14 main-menu[4663]: (process:25067): dpkg-divert: warning: diverting file '/sbin/start-stop-daemon' from an Essential package with rename is dangerous, use --no-rename Apr 7 08:05:14 main-menu[4663]: (process:25067): dpkg-divert: warning: diverting file '/sbin/start-stop-daemon' from an Essential package with rename is dangerous, use --no-rename Apr 7 08:05:14 main-menu[4663]: (process:25067): /usr/bin/grub-installer: Apr 7 08:05:14 main-menu[4663]: (process:25067): line 252: Apr 7 08:05:14 main-menu[4663]: (process:25067): /usr/lib/grub-installer/mkhfs-bootstrap.sh: not found Apr 7 08:05:14 main-menu[4663]: (process:25067): Apr 7 08:05:14 main-menu[4663]: WARNING **: Configuring 'grub-installer' failed with error code 1 Apr 7 08:05:14 main-menu[4663]: WARNING **: Menu item 'grub-installer' failed. At this point I stopped the installation. Hope this report helps. Regards. [1] https://cdimage.debian.org/cdimage/ports/2019-04-06/ [2] ftp.ports.debian.org/debian-ports/
