Public bug reported:
Downloaded Kubuntu 21.04 ISO & checked SHA256, perfect match. Tried
burning with K3B to a 4GB DVD. Stopped at 98% with a message "Fatal
error during recording: Invalid argument." & ejected the DVD. I tried it
on another machine, SAME problem. I then ran a simulated burn on both
machines, to check it wasn't a HW problem, the same problem again. I'd
already burned Kubuntu 20.04.3 to a DVD a couple of days before without
any trouble at all! So I downloaded Kubuntu 21.10 (Beta), with the same
results, the burn failed at 98%.
