Using a CD as an apt repository doesn't work.

[Sam Townsend]

Binary package hint: apt

"apt-cdrom add" does add the CD to sources.list and updates correctly, but trying to install anything from the CD fails, stating that it can't find it.

Furthermore, the "Add CD-ROM" button in Software Sources always spits out "E:Failed to mount the cdrom.", regardless of whether the CD is already mounted or not, or if there is even one in the drive.
