After doing that, it occurred to me, that the defined error, is not in
the content of the file, but, in the file name;
"
N: Ignoring file 'opera.list.save' in directory
'/etc/apt/sources.list.d/' as it has an invalid filename extension
"
So, to me, the file name itself, is not compatible; the
"opera.list.save" file name.
