I've been getting the following message every day from the apt-cacher-ng
cron job:
/etc/cron.daily/apt-cacher-ng:
Error(s) occured while updating volatile index files for apt-cacher-ng.
Please visit http://proxy.localnet:3142/report.html to rerun the
expiration manually or check the error message(s) in the current log file(s).
When I run it, I always get errors on the exact same files. It is always the *.xz files.

I delete them and the apt-cacher-ng web interface is happy, but as soon as I do an apt-get update on one of the clients. These files are back with exactly the same error.
I've been searching around for a solution to the, but can't seem to find anyone with this problem.
I'd exactly the same problem and found this official Debian bug report. Installing a newer version of apt-cacher-ng package solved the issue for me. If you're still using wheezy (like I do), try to download and install the backport manually.
