Note that the default setup will not automatically install the updates (there are some good reasons to not do this), but you can config it to do so. This will send an email every time it runs, not only if it encounters an error. One thing I add to my configuration is: MAILON='always'

The main configuration file is /etc/cron-apt/config Unattended-upgrades has that option, and in my experience reboot after kernel upgrade works with the fix above. I'm not sure cron-apt can automatically reboot your system after a kernel update. Cron-apt is your second-best option, because it's also designed for a similar purpose. It's recommended to use unattended-updates and fix the package, because it's best suited for the purpose. You will probably need to install new apt keys for the debian repository. Your options are:Įcho 'Unattended-Upgrade::Origins-Pattern ' | sudo tee /etc/apt//51unattended-upgrades-raspbianįor faster security updates (but less stability, as the packages haven't been approved for rasbian), you can add debian-security packages to apt: echo 'deb buster/updates main contrib non-free' | sudo tee /etc/apt//debian-security.list It won't install crucial updates for the kernel and other software. In its default configuration, unattended-upgrades is broken in Raspbian Buster.
