2 problems with updates on k12ltsp 4.2: Yum is complaining about not having the GPG key for an acroread update. The dovecot update enables dotlock locking for mailboxes but it doesn't have write access to create the file (and shouldn't need it anyway). The fix is to add/change mbox_locks = fcntl in /etc/dovecot.conf. -- Les Mikesell les at futuresource.com
