Hi Niels,
using noawait fixes the issue:
root@lettie:/tmp# dpkg --unpack php5-common_5.6.4+dfsg-3_amd64.deb
(Reading database ... 15181 files and directories currently installed.)
Preparing to unpack php5-common_5.6.4+dfsg-3_amd64.deb ...
Unpacking php5-common (5.6.4+dfsg-3) over (5.6.4+dfsg-3) ...
root@lettie:/tmp# dpkg --configure --pending
Setting up php5-common (5.6.4+dfsg-3) ...
Processing triggers for libapache2-mod-php5 (5.6.4+dfsg-3) ...
Thanks for catching that.
Cheers,
Ondrej
