Bug#721349: dlocate vs. mystery files in /var/cache/apt/

[jidanni@jidanni.org]

Package: apt
Version: 0.9.11.1
Severity: wishlist

I found a file, "ae".

# ls -l /var/cache/apt/
-rw-r--r-- 1 root root 21946941 08-20 07:37 ae
drwxr-xr-x 4 root root   131072 08-29 08:00 archives
-rw-r----- 1 root root        0 06-04 18:22 lock
-rw-r--r-- 1 root root 22019209 08-30 22:27 pkgcache.bin
-rw-r--r-- 1 root root 21973872 08-30 22:27 srcpkgcache.bin

Can I remove it?

What made it?

# dlocate /var/cache/apt/
apt: /var/cache/apt/archives
apt: /var/cache/apt/archives/partial

doesn't mention it.

Nor does it mention

lock
pkgcache.bin
srcpkgcache.bin

That's the problem,

nobody knows what belongs to what.

But maybe there is a rule that those kinds of files should never be
listed.

So it is all a big guessing game.
