Thanks for the confirmation.

This looks bad. Looks as if the md5sum of all these files is broken,
i.e. they don't have the contents they should have. (See
http://rpm.org/max-rpm-snapshot/rpm.8.html#AEN19947 for details on how
to read those lines.)

Nope.

If "ls -l /var/cache/apt/archives/*_1.0.9.8.4_*.deb" still yields
something, calling the following command as root hopefully fixes this
issue:

  dpkg -i /var/cache/apt/archives/*_1.0.9.8.4_*.deb

If they're no more there (or it doesn't solve the issue due to broken
.deb files on disk), I recommend to call "apt-get download apt
libapt-inst1.5 libapt-pkg4.12" on another amd64 Debian 8 Jessie
machine (for easy download verification) and copy the
/var/cache/apt/archives/*_1.0.9.8.4_*.deb files over to the broken
machine via e.g. scp, then install them via dpkg like above (but with
a possibly different path).

If all that doesn't help, there's likely something fishy with either
the file system or the disk below it.

For now, I'm leaving the bug report open until it's clear if it's just
a local (maybe hardware) issue or if there's a real and seldom
occurring bug lingering in here.
