[syslog-ng] unable to install syslog-ng ubuntu 16.04

Indeed, I think the problem is that syslog-ng core depends on
syslog-ng-mod-journal, which recursively depends on syslog-ng-core through
a Provides line.

Hmm.. the funny part that a week ago I successfully installed the same
package on one of my servers, but now in a clean docker container I
couldn't do that.

I have a workaround, attached you'll find an equivs compatible control
file, that provides the missing dependency, once that is installed,
"apt-get install syslog-ng" works.

It goes like this:

# dpkg -i syslog-ng-abi-3.8-0_3.8.1-1_all.deb
Selecting previously unselected package syslog-ng-abi-3.8-0.
(Reading database ... 7256 files and directories currently installed.)

Unpacking syslog-ng-abi-3.8-0 (3.8.1-1) ...
Setting up syslog-ng-abi-3.8-0 (3.8.1-1) ...
# apt-get install syslog-ng-core

The following additional packages will be installed:

libnet1 libpopt0 libssl1.0.0 libwrap0 libxml2 logrotate sgml-base
  shared-mime-info syslog-ng-mod-journal tcpd xdg-user-dirs xml-core
Suggested packages:
  anacron checksecurity exim4 | postfix | mail-transport-agent mailx
sgml-base-doc syslog-ng-mod-sql syslog-ng-mod-mongodb syslog-ng-mod-json
  syslog-ng-mod-smtp syslog-ng-mod-amqp syslog-ng-mod-geoip
syslog-ng-mod-redis syslog-ng-mod-stomp syslog-ng-mod-riemann
syslog-ng-mod-graphite
  syslog-ng-mod-python syslog-ng-mod-java syslog-ng-mod-java-common-lib
syslog-ng-mod-elastic syslog-ng-mod-hdfs syslog-ng-mod-kafka
syslog-ng-mod-http
  syslog-ng-mod-curl syslog-ng-mod-kvformat

The following NEW packages will be installed:

Do you want to continue? [Y/n]


The "syslog-ng-core" package only contains a subset of the syslog-ng
package, pulling in a smaller set of dependencies, whereas syslog-ng is the
full set.

The abi package here is just a fake one, I'll make sure this packaging
issue gets fixed.
