Hi Debian Haskell Team,
First off, thanks for all the hard work. I have been using different ghc
stable releases from deb.haskell.org repos for quite some time without
any issue.
I also use the latest build from time to time and in the past it has
installed and upgraded without issue. I just got a new laptop and added
the following to my /etc/apt/sources.list file (I'm on unstable):
deb http://deb.haskell.org/dailies/latest/ ./
deb-src http://deb.haskell.org/dailies/latest/ ./
When I update and try to install, I receive the following error:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
ghc : Depends: libffi5 (>= 3.0.4) but it is not installable
E: Unable to correct problems, you have held broken packages.
---------- end console output ----------
I can see there is a problem with libffi5 but I'm not entirely certain
how to go about fixing it. Any idea what is happening?
I would love to help out so let me know if there is anything else I can
do.
Thanks!
