Burning iso with k3b

[marshallbanana]

I'm trying to burn the hardy alpha 5 iso with k3b (in gutsy). The md5 sum is completed fine and then when I click 'start' if gets to the following steps:
...
Sending CUE Sheet
Starting disc write
Cdrecord has no permission to open device

Does anyone have any ideas as to how to solve this permissions error? I tried running 'kdesudo k3b' but the just resulted in the same as above.

Hmm - here (K3bSetup output, removed from the official Kubuntu k3b):

Re: Burning iso with k3b

Thanks Rog, I ran those and got slightly different permissions settings on those /wodim executables. The following is what I got however I am not sure exactly what I should be changing the permissions to:

ls -l /usr/bin/wodim

-rwxr-xr-x 1 root root 359116 2007-09-17 08:17 /usr/bin/wodim

and

ls -l /usr/X11R6/bin/wodim

-rwxr-xr-x 1 root root 359116 2007-09-17 08:17 /usr/X11R6/bin/wodim

If someone could tell me what I need to set the permissions to exactly that would be great.

Note: cdrom was in my secondary groups

Re: Burning iso with k3b

I have this exact same problem. It unfortunately occurred when I downloaded the Kubuntu ISO image and attempted to burn it to a CD to give to a Windows user and install on a laptop. It was extremely embarrassing.

I have seen the cryptic assistance offered and I do have the CD device listed in my secondary groups.

Can anyone explain how to fix this problem

And maybe why we have this problem to begin with?

Maybe:

k3b burning failed- cdrecord has no permission to open the device

[SOLVED] K3b says, "Cd record has no permission to open device"

Re: Burning iso with k3b

I have, typed in a terminal session

Code:
dmesg | grep -i cd | grep -i romthis should identify your devices Now type

and then

Code:
sudo chmod 777 /dev/scd0- replacing "scd0" with my id own device.

I still recieve the exact same error. The above "fix" appears to have done nothing for me. Are there any additional suggestions?

Re: Burning iso with k3b

From /usr/share/doc/k3b/README.Debian

Users must be members of the "cdrom" group
------------------------------------------

To be able to access the CD/DVD burner, users must be members of the "cdrom"
group. To check whether you are a member of that group, run the following
command:

groups

If you don't see the "cdrom" group, ask the administrator to be added to that
group or run the following command as root:

adduser [username] cdrom

If you are already a member of the "cdrom" group and are experiencing problems,
then you may need to give SUID privileges to wodim. To do this, run the
following command as root:

dpkg-statoverride --add root cdrom 04710 /usr/bin/wodim

-- Francois Marier <francois@debian.org>, Fri, 3 Dec 2006 16:38:14 -0500

Francois Marier tells in the /usr/share/doc/k3b/changelog.Debian:

...K3b should be working out of the box on Debian,
otherwise it's a bug that needs to be fixed, not worked around...

=> If:

sudo dpkg-statoverride --add root cdrom 04710 /usr/bin/wodim

doesn't help, then it is bug. Maybe bug report helps =>

Re: Burning iso with k3b

1. To be able to access the CD/DVD burner, users must be members of the "cdrom"
group.

2. If you are already a member of the "cdrom" group and are experiencing problems,
then you may need to give SUID privileges to wodim. To do this, run the
following command as root:

dpkg-statoverride --add root cdrom 04710 /usr/bin/wodim

I have performed each and every step in this and the Ubuntu threads.

NO JOY!! Still doesn't work and the error is still the same.

Thanks for trying Rog131

Re: Solved for me - Burning iso with k3b

First my apologies for hi-jacking this thread.

It turns out that the error message I received concerning lack of permissions was completely BOGUS. By slowing my burner to 8x and changing the write mode to TAO, the ISO burned just fine. I do not know if the fix was the speed, the mode, both, or neither but it works.

K3B Wodim Issues UNRESOLVED

I have no luck even with changing the write speed to the slowest available. I've tried all the "fixes" out there for this too. My permissions are correct for every thing
