The configuration file shipped with the collectd package only loads these plugins by default: marc@lonquimay:~/src/pkg-collectd/debian$ grep ^LoadPlugin collectd.conf LoadPlugin syslog LoadPlugin battery LoadPlugin cpu LoadPlugin df LoadPlugin disk LoadPlugin entropy LoadPlugin interface LoadPlugin irq LoadPlugin load LoadPlugin memory LoadPlugin processes LoadPlugin rrdtool LoadPlugin swap LoadPlugin users None of them depend on libsensors4 or liboping0 (the sensors and ping plugins do, but they aren't enabled by default). So my guess is that this system previously had a non-default configuration (maybe some config snippets in /etc/collectd/collectd.conf.d/ ?) in place, and installing/upgrading collectd-core made the missing runtime dependencies strike out. Are you able to confirm ? NB: I agree such a failure is undesirable. The collectd plugin loading mechanism could maybe be changed to not abort startup in this case (just skip loading the plugin and emit an error message). > Manual installation of libsensors4 liboping0 solved the issue. > > When a package won't complete it's installation without a > package, it should be a requirement, not anything less. > > Probably an issue with the debian packages as well. Are you aware of /usr/share/doc/collectd-core/README.Debian.plugins.gz ? Cheers, Marc
