Stale images / expired gpg keys

[redterror]

Hi, while attempting to use the nrpe-server:full package as a base container for my own nrpe-server, I ran into several build issues:

• GnuPG keys linked to the private apt repository are expired.
• The stale container predates the Debian UsrMerge business (see: https://wiki.debian.org/UsrMerge) and as a result, if I try to install gettext-base, the dependencies throw errors like:

#0 8.846 Preparing to unpack .../base-files_13.3_amd64.deb ...
#0 8.865

Is there any capacity to freshen up and build / release a newer image?
