https ://www.raspbian.org/RaspbianRepository suggests that wheezy would be the "official" current suite of the Raspbian distribution.
I cannot believe that, though, because I have been using "jessie" as "stable" instead for the last years, which is the successor of "wheezy".
And since "stretch" has been out, I changed my /etc/apt/sources.list to the following:
$ find /etc/apt/sources.list* -type f | xargs sed '/^deb/!d' deb http://mirrordirector.raspbian.org/raspbian/ stable main contrib non-free rpi firmware deb http://archive.raspberrypi.org/debian/ stretch main ui
I also ran "apt-get dist-upgrade" from "jessie" to "stretch" successfully, which downloaded and installed about 1 gig of *.deb files as part of the process.
But even though "apt-get update" is able to fetch all the package lists without problems, I never got any updates for a week or so.
I cannot believe there have not been any security updates since then, so I am worried that my sources.list/sources.list.d/* may be incorrect.
I tried changing back "stretch" to "jessie", but no updates either.
Can anyone tell me why I am obviously missing the latest security upgrades?
