I pull Brasero off my installs immediately so I haven't personally seen it, but from what I'm finding it looks like verification is under Tools, Verify Integrity.
Hi and welcome. It's the same when I burn an .iso with K3b. At the end it will indicate that the image has burned successfully and also provide a sound confirmation too, usually a 'ping'.
Thank you for your recommendations. I've tried k3b but for some reason I ran into a problem, where it would hang on me when switching from burning to verifying mode. I will give another chance because it seems like I've had an older version from apt and now I'm seeing version 25 snap package. I'll try it in few days.
