Comment 1 for bug 1375919

For wheezy I can confirm this. The line has been removed from the Jessie version.

For wheezy, it can be fixed by making it like this:
"origin=Raspbian,codename=wheezy,component=main";

Or just remove the line.

For Jessie it can stay like this or it could be changed to:
"origin=Raspbian,codename=jessie,component=main";

Which can be commented out by default.
