The sources.list entry is for a cdrom that does not exist: the install method was via a USB stick. That certainly seems like a bug to me (and one that I've hit before myself: but I have not checked whether it is already reported.) Even if the OP left the install USB plugged into their machine, the sources.list line would never work. -- Jonathan Dowland
