I don't have error message.
In "sorgenti software" in the third field i removed all repository about opera (I had 2 urls) . Than i reinstalled Opera 40.0.2308.62
Now in repository i have only this URL : deb https://deb.opera.com/opera-stable/ stable non-free #Opera Browser (final releases)

So just do it. Remove opera/ from the end of the url.

Apparently, their repository changed and a path opera was added before the dists directory. So all you have to do is:
sed -i 's/\(opera-stable\)/\1\/opera/' /etc/apt/sources.list.d/opera-stable.list
And then upgrade normally.
