[Bug 1050779] [NEW] excessive backup pkgcache.bin files retained

[Michael Vogt]

Public bug reported:

TEST CASE:
1. sudo rm /var/apt/cache/*.bin
2. "sudo apt-cache gencaches"
3. ctrl-c in the middle of it
4. sudo apt-get update
5. verify with ls -l /var/cache/apt/ that there is a leftover file

6. install the update
7. repeat 1-4
8 verify with ls -l /var/cache/apt that no files are leftover


Apt can leave backup pkgcache.bin files around:

$ ls -l /var/cache/apt
