moodle failed to install/upgrade

Binary package hint: moodle

Excuse my ignorance; I just downloaded Wubi and am using it for the first time. I used synaptic package manager to download moodle. After the download did whatever it's supposed to do, it said there was a piece missing, but I didn't get what that piece was. I didn't think much of it, 'cause the error report message didn't show up till about 5 mins. later. Maybe one of the files isn't linked to the whole package?
