This has been fixed in the apache2 source package by splitting off an
apache2-ssl-dev package from apache2-dev. Merging this bug report with
#845033 (https://bugs.debian.org/845033) as it has been done with the
according FTBFS bug report against cgit.

This is because apache2-dev (which provides dh-apache2) depends on
"libssl1.0-dev | libssl-dev (<< 1.1)". So the reason are conflicting
build-dependencies because some build-dependencies are ready for
OpenSSL 1.1 and others are not.

I'm not sure if this is really an issue of xymon. It could be
workarounded by using "libssl1.0-dev | libssl-dev" in xymon, but then
xymon in Debian needlessly would be build against OpenSSL 1.0.x which
I at most consider a temporary solution.

Please advise how to proceed.

Hi,

During a rebuild of all packages in sid, your package failed to build on
amd64.

The full build log is available from:
   http://aws-logs.debian.net/2016/11/18/xymon_4.3.27-3_unstable.log

A list of current common problems and possible solutions is available at

About the archive rebuild: The rebuild was done on EC2 VM instances from
Amazon Web Services, using a clean, minimal and up-to-date chroot. Every
failed build was retried once to eliminate random failures.
