Package: apt
Version: 1.3~pre2
Severity: grave
Justification: causes non-serious data loss
(well, not when run as a normal user, but it would when run as root)

"apt upgrade -s" should be non-destructive, but it tries to remove a
file (here, it couldn't, but just because I didn't run it as root):

cventin:~> apt upgrade -s
NOTE: This is only a simulation!
      apt needs root privileges for real execution.
      Keep also in mind that locking is deactivated,
      so don't depend on the relevance to the real current situation!
