here is sudo apt-get install ending now with:
Trigger for initramfs-tools are processing ...
update-initramfs: Generating /boot/initrd.img-3.5.0-19-generic
... then here comes this:
failure while processing:
postfix
E: Sub-process /usr/bin/dpkg returned an error code (1)
what shall I do to iron this in 12.10 ?
