Installing the fixed file is not really a work around but the error piping would work. I'll live with the noise for now and try to get the updated package installed once it reaches xenial-backports.

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.
