Bug#808802: #808802 synaptic: Can't drop privileges for downloading as file '/var/lib/apt/lists/partial/ftp.fr.debian.org_debian_dists_testing_InRelease'

[Tsu Jan]

It seems that this issue is fixed by apt-1.2 but it's replaced by 
another message:

The method driver /usr/lib/apt/methods/https could not be found. I hope 
the latter will be fixed by apt-1.2.1, which I haven't tried yet.
