Dear Maintainer,
I can't burn DVDs or from K3B or command from console.

The detected error is as follows:
":-( Unable to O_Excl / dev / SR0: SomeOone Was in Time to Remount?"

Thanks,
Antonio

To solve the problem, I had to insert this line
(https://it.wenda123.org/question/askubuntu/61684/growisofs-fails-with-unable-to-o-excl-dev-scd0-someone-was-in-time-to-remount):

/dev/sr0   /media/cdrom   iso9660   rw,noauto,user,exec   0   0

while so far it worked well without, something has changed but I don't
know what...
