Bug#993296: growisofs: Can't burn the DVD (solved)

[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...
