Since update to 11.04, I keep receiving messages from 'Anacron', with some errors. Two types of messages, actually.

The first of those types is like:

/etc/cron.daily/logrotate:

/etc/denyhosts.conf: 28: SECURE_LOG: not found

/etc/denyhosts.conf: 36: HOSTS_DENY: not found

/etc/denyhosts.conf: 60: PURGE_DENY: not found

/etc/denyhosts.conf: 95: BLOCK_SERVICE: not found

/etc/denyhosts.conf: 110: DENY_THRESHOLD_INVALID: not found

/etc/denyhosts.conf: 121: DENY_THRESHOLD_VALID: not found

/etc/denyhosts.conf: 131: DENY_THRESHOLD_ROOT: not found

/etc/denyhosts.conf: 142: DENY_THRESHOLD_RESTRICTED: not found

/etc/denyhosts.conf: 155: WORK_DIR: not found

/etc/denyhosts.conf: 200: LOCK_FILE: not found

/etc/denyhosts.conf: 221: ADMIN_EMAIL: not found

/etc/denyhosts.conf: 232: SMTP_HOST: not found

/etc/denyhosts.conf: 233: SMTP_PORT: not found

/etc/denyhosts.conf: 252: Syntax error: newline unexpected

error: error running non-shared postrotate script for /var/log/denyhosts of '/var/log/denyhosts '

run-parts: /etc/cron.daily/logrotate exited with return code 1

These are the corresponding entries in /etc/denyhosts.conf

SECURE_LOG = /var/log/auth.log

HOSTS_DENY = /etc/hosts.deny

PURGE_DENY = 1w

BLOCK_SERVICE  = sshd

DENY_THRESHOLD_INVALID = 5

DENY_THRESHOLD_VALID = 10

DENY_THRESHOLD_ROOT = 1

DENY_THRESHOLD_RESTRICTED = 1

WORK_DIR = /var/lib/denyhosts

LOCK_FILE = /var/run/denyhosts.pid

ADMIN_EMAIL = root@localhost

SMTP_HOST = localhost

SMTP_PORT = 25

All of them seem fine to me.

Also, lines 251-253 in the same file go like:

#

SMTP_FROM = DenyHosts <DenyHosts@localhost>

#

So I don't see the "unexpected newline", either...

The other type of mail message I get from 'Anacron' is:

/etc/cron.daily/popularity-contest:

readline() on closed filehandle FILES at /usr/sbin/popularity-contest line 104.

(with the former line repeated some tens times)

Any hint on these messages?
