however, the burn always reports as failure. Failure of what is unclear. The md5 checks out as fine.

I'm burning a Linux ISO, ViciBox, from Ubuntu. I've gone through a few DVD's, and am now just simulating burning to disc with K3B. I don't see a particular failure message:

Notably, K3B does confirm the md5 sum:

which matches the md5sum:

no, I'm not asking about a different distro, I just want to burn this ISO from Ubuntu and am trying to understand the debugging output.
Best Answer
------update-----
After the medium was tested and rated "excellent":
If the MD5 from DVD-R matches the MD5 of the ISO, then the burn run succeeded. The DVD is supposed to work for its purpose of booting. Did you already try ?
It looks like the error message from K3B is mislead. (Shrug)
------end update-----
What symptoms tell you that it failed ?
I guess you cannot read it, but even that can have various reasons. If the medium stays just blank without any other error indication, then either you have inadvertedly enabled simulation or your burner drive is going bad.
The state of the medium may be inquired by
Since you just want to burn an ISO, i propose you make further experiments by skipping the GUI layer and starting growisofs directly. The following proposal is derived from the growisofs command reported by K3B. Excute it in the directory where the ISO ist stored (or use its absolute path):
The option
causes burn simulation on DVD-R, which of course would prevent real burn success.
Have a nice day :)
