Debian 9.30 Maintenance
I spent some time hunting thru the Synaptic Package Manager for the package updater but I didn't find it.
I'm thinking a combination of apt-get update followed by apt-get upgrade -- will probably suffice, except for the kernel, maybe--
too, trips to the backports are needed at times, Darktable being one I've needed several times.
we should be on Firefox 58 but I see we are on 52.
