Norbert, it is *extremely* inappropriate to edit the bug description to
publicize your workaround. Adding instructions to set the sandbox user
to "root" at the start of the bug description is quite simply awful.
I have reverted that change.
** Description changed:
READ ME FIRST
This is a cosmetic issue. The warning message is just that— a warning. Though
the message comes up, there is no problem with the install/upgrade happening
like normal. That said, feel free to ignore it. It will get fixed, but it's
nowhere near as urgent as bugs that actually result in the wrong behavior
rather than just a simple extra message.

Recently we got new versions for synaptic 0.82+build1 & apt 1.1.3, but
now get that error when installing/upgrading some packages:
Setting up libc6-dbg:amd64 (2.21-0ubuntu5) ...
Processing triggers for libc-bin (2.21-0ubuntu5) ...
W: Can't drop privileges for downloading as file
'/root/.synaptic/tmp//tmp_cl' couldn't be accessed by user '_apt'. -

From nautilus, i'm seeing a /root/ folder locked (x on its icon) and the
folder is empty (no /.synaptic/ sub-folder or file), so the above error.
