[K12OSN] Cannot find valid baseurl for repo: k12ltsp

[petre at maltzen.net]

I installed version 4.2.1, ran 'yum update', but now whenever I run yum, I
get

Cannot find a valid baseurl for repo: k12ltsp

/etc/yum.repos.d/k12ltsp.repo looks like this:

[k12ltsp]
name=K12LTSP
mirrorlist=http://k12linux.mesd.k12.or.us/mirrors/k12ltsp-4.2
gpgkey=http://k12linux.mesd.k12.or.us/K12LTSP-GPG-KEY
enabled=1
gpgcheck=1

Can anyone tell me what's wrong here?
