Public bug reported:
Periodically I get emails from a machine with the subject:
Cron <root@Jenkins> if [ -x /etc/munin/plugins/apt_all ]; then
/etc/munin/plugins/apt_all update 7200 12 >/dev/null; elif [ -x
/etc/munin/plugins/apt ]; then /etc/munin/plugins/apt update 7200 12
>/dev/null; fi
And a body of:
AppStream cache update completed, but some metadata was ignored due to
errors.
I have a machine monitored by Munin. One of the plugins used on that machine
is /etc/munin/plugins/apt which periodically counts the number of packets that
can be upgraded. This is achieved by a crontab entry installed from the
package which looks like this:
#
# cron-jobs for munin-node
#
MAILTO=root
# If the APT plugin is enabled, update packages databases approx. once
# an hour (12 invokations an hour, 1 in 12 chance that the update will
# happen), but ensure that there will never be more than two hour (7200
# seconds) interval between updates..
*/5 * * * * root if [ -x /etc/munin/plugins/apt_all ]; then
/etc/munin/plugins/apt_all update 7200 12 >/dev/null; elif [ -x
/etc/munin/plugins/apt ]; then /etc/munin/plugins/apt update 7200 12
>/dev/null; fi
For many months everything has been running smoothly. On the 23rd November
2016 I started getting the "AppStream cache update completed, but some metadata
was ignored due to errors." messages at a rate of about ten a day.
I did a quick Google search which turned up a handful of bugs from earlier this
year, such as
Bug1575248. That is marked as Fixed Released though, so I am raising this new
bug.
If there are any further diagnostic details I can provide, please let me
know.
