creating mylivecd!!

[gezza]

Hi,
I have a fully updated 2010.12 system and all is running very well.
However although I can create a livecd iso image, any way I burn it gives no errors but the resulting DVD fails the media test and indeed does not boot.
This is on all machines and laptops. I have used DVD -R and DVD +R disks.
Any thoughts?

When creating a livecd of pclinuxos, if k3b burns the *.iso correctly how can media check fail?
Or another question: is it possible for mylivecd to produce an incorrect image that k3b will burn with no errors but the media check will then fail?

Hi She_Devil
I have not created a working livecd since about 2010.10
I get the livecd created without errors, I get a k3b burn without errors.
I get no working dvd, it fails at media check. It generally is no good but occasionally it is good. about 1 in 100 burns.
I have tried it on 2 desktop machines and 2 laptops..no go.

gezza,  update mylivecd from synaptic and try again.. The issue has been resolved with creating ISOs now.  Have fun!!

Linuxera you are getting too far ahead. There are two more fixes to do.

Okay dokay, Tex.    ..

I have just done an update and installed a new version of mylivecd.
results not good. created a 2.2GB iso in 1 hour on a 3 core AMD 2.3Ghz machine, burnt a failed DVD -R, then a success DVD +R.
However it failed the media test.

What speed are you burning the ISO at gezza... the slower the better.  I have successfully created and burned many ISO's.

Have just updated again and installed a newer version of mylivecd.
We still have problems: although the image was created by mylivecd (1.9GB) and the image was burnt with k3b.
The burn was again successful but the media test again failed.
The DVD did boot but had a problem with the disk setup/installation.
We get the following error: Undefined subroutine &fsedit::isLUKS called.

ps...This is from the livecd just created.
Addition 1..
Hi Linuxera
It is a very good question.
I set k3b to burn a 4X but it burnt at 16.4X which is the max speed of the DVD +R disk.
Gezza
Addition 2...
More testing...
If k3b reads the mylivecd.iso image and creates a checksum based on the livecd.iso file, then burns that to a DVD, then verifies the burnt image against the .iso file then says all is OK, the livecd.iso creation must in itself in error.
It does not image all the files in the system!!!!

Gezza,

I just got the same message when using the install function.
Texstar is or has uploaded an update to mylivecd script.

I read it on his twitter account.

Might make a difference,

Hello.  I tried unsuccessfully earlier today to install from a live cd.  The cd md5sum is correct and the disk passed 'mediacheck'.

The installation process failed when I tried to set a partition to mount '/'.  The error message each time (I tried 2 partitions) was:

Undefined subroutine & fsedit;;isLUKS called

What to do?  Thanks for any help.

I can confirm this error. I have been getting it after some recent updates. Newer Mylivecd and drakxtools packages have been hitting the repo. I install and remaster, but the same error exists when trying to partition. Even "Use existing partitions" gives the error.

Workaround for time being: use gparted (or another partioning tool) to create the partitions, then in live installlation choose "custom disk partitiong", just keep the existing partitions and click next, it will skip over the partitioning bug and install successfully.

I'm glad it wasn't something I've done wrong, hopefully it will get fixed soon.
