Comment 4 for bug 1983856

I'm afraid that even with a single client it seems to randomly logs this line:
  storage error [Checked size beyond EOF], check file AND directory permissions, last errno: File exists

I'm deleting the failed temporary files:
  sudo find /var/cache/apt-cacher-ng/ -name 'InRelease.[0-9]*' -delete
But it only randomly helps a bit for newly runned apt-get clients' processes.

When client fails to update it's cache, it says:
  500 Cache Error, check apt-cacher.err [IP : x.x.x.x 3142]

However, that's quite an annoying bug, because it crashes client's Unattended Upgrade. Their apt-get process stays waiting forever, which blocks any other apt-get! If not supervised, we would miss security updates without even knowing it!
