JohnBoy:  I think you have played with this before..... Did you ever find a solution to the DBUS error?


Could one of our esteemed graphics gurus pclosify this image please?
Edit:
Looks like we got us a graphic.

liveusb-creator asks for root password but fails.......

running dbus-launch liveusb-creator as root, seems to be working.  Will now attempt to make a persistent live-usb.  Thanks Tex!

Hmm.  Would we have to do the iso differently?  Crud, so close..... more research required.

OOOH!  A Clue!

i've the feeling that you are almost there and very soon we all will be enjoying your liveusb-creator ...
thanks for your work!

Joble, I see Tex got in on the D-bus question ......  just as well as I did not remember 

I looked at this utility some time ago, and (IIRC) it was my impression then, that there would have to be some changes made to the app to accomodate the structure of a PCLOS ISO. I may have been misunderstanding it at the time but think it would be worth checking out.
Of course if this has been ported to Mandy that would help a lot

Where do you think I got the rpm from?

Oh foolish me ......  I thought you were working from source

I think slick50 may be on to something:
isomd5sum
Utilities for working with md5sum implanted in ISO images
The isomd5sum package contains utilities for implanting and verifying
an md5sum implanted into an ISO9660 image.

I don't think I ever embedded my md5sum into my iso images, since I created them and I knew where they came from.  Wonder if the md5sum is embedded in our iso's?

From slick50:

That's ok I built it myself... Now a lot of work I see as it has to be competely
reworked (liveusb) halfway there.

I usually take pride in beating him to a package request.  In this case, obviously, I can use all the help I can get.  

I can only imagine what this patch is gonna look like.

Your output above reported

ISO MD5 checksum passed
Extracting live image to USB device...
Unable to find LiveOS on ISO
LiveUSB creation failed!

Implies to me that the md5sum is OK.

It finds the ISO image but fails to find whatever it is looking for within the ISO ......  is it looking for a differently named file than the PCLOS livecd.sqfs file or whatever it is looking for?

So what does it search for within the ISO after confirming the MD5sum is correct?

[Joble]

Hmm..... Interesting observation. 

* Joble runs off to check.

I think slick50 is all over that based on his last PM.

                delta = datetime.now() - start
Maybe adding livecd.sqfs would help?

Sheesh.... You should be a packager dude!
