OK, the first problem I ran into is that the Gparted program on the  
Dapper flight 3 PPC live-CD does not seem to be able to create a boot  
or a root partition. I couldn't find any other programs on the disk  
that could be used as an alternative either :-( I also have the  
Kubuntu live-CD, but when I can't even get the drives to show up  
properly (as per an earlier e-mail) that doesn't seem to be a viable  
way to go either. Normally, I would then try a Breezy CD, to get more  
stability, but as I stated earlier, nothing before Dapper will even  
boot on my PowerMac G5.

One thing that has struck me so far on this list, is that there  
doesn't seem to be any of the developers of the PPC version of Ubuntu  
lurking on the list, nor do there seem to be very many Mac users. On  
the YDL list (which is of course Mac centric), they have asked me to  
clarify that I have a PowerMac G5 and not an iMac G5, they have also  
asked me to check my firmware version, which I believe is listed as:  
" Boot ROM Version:	5.2.2f2", etc. Not even a response on this list  
when I quoted the Debian lists response to my problem, stating that  
there was no longer any contact between the two kernel groups (?!?).

Personally, I really like Ubuntu/Kubuntu and I would prefer to have  
that installed on my PowerMac G5, but at this point, it isn't looking  
too good. I hope this doesn't sound like I am ungrateful for the help  
I have received so far, because I am very grateful. I am just  
frustrated about hitting what looks like a brick wall at this point.

I have had a look at https://launchpad.net/malone but can't figure  
out how to file a bug. I have searched and found that the bug doesn't  
seem to be listed. BTW, the link doesn't seem to work properly in  
Safari. I get the following prompt: Safari wants permission to sign  
using key "-" in your keychain. Do you want to allow this? (Deny,  
Allow Once, Always Allow)"
