Looking for pointers on a package configuration issue. This is a stripped down version of Debian 8 (ReadyNAS 6.10.3 running on a Netgear RN202 NAS).
I think the problem may have been triggered by installing the third-party RNXtras PHP7.2 app that upgrades the default PHP from 5.6 to 7.2. The combination worked fine when I first installed it a while back. But ReadyNAS (Debian) was upgraded on the box since then, and after doing a recent full wipe / install of ReadyNAS then reinstall of RNXtras PHP7.2, things went south: Both an uninstall and install of RNXtras PHP7.2 is failing now - as are other installs.
The primary symptom right now is this sort of thing:
# apt-get install git ... insserv: warning: script 'K01ddclient' missing LSB tags and overrides insserv: Service nfs-common has to be enabled to start service nfs-kernel-server insserv: Service rpcbind has to be enabled to start service nfs-kernel-server insserv: exiting now! update-rc.d: error: insserv rejected the script header dpkg: error processing package nfs-kernel-server (--configure): subprocess installed post-installation script returned error exit status 1 Setting up liberror-perl (0.17-1.1) ...

Also, similar errors for "apt-get remove", etc.
Perhaps this could be solved through package pinning, but not sure where to look.
