Version of aces3 is marked for autoremoval from testing on Mon 04 Sep 2017. It depends (transitively) on csh, affected by 853361. You should try to prevent the removal by fixing these RC bugs.
The package should be updated to follow the last version of Debian Policy
(Standards-Version 3.9.8 instead of
3.9.6).
testing migrations
This package is part of the ongoing testing transition known as libgfortran4.
Please avoid uploads unrelated to this transition, they would
likely delay it and require supplementary work from the release
managers. On the other hand, if your package has problems
preventing it to migrate to testing, please fix them
as soon as possible.
You can probably find supplementary information in the
debian-release
archives or in the corresponding
release.debian.org
bug.
