Next we want to instruct the updater to send emails. sudo sed -i 's/^\/\/ "o=Raspbian,n=jessie"/ "o=Raspbian,n=jessie"/g' /etc/apt//50unattended-upgrades This config lives in /etc/apt//50unattended-upgrades and you can use this script to uncomment the line for Jessie. I’ve decided to stick with Jessie for now. ![]() Next we should configure where the updates are allowed to come from.If you choose to stick with Stable then when the next version of Raspbian goes stable (Stretch) it’ll automatically update. apt-listchanges also requires a mailx program so if you don’t already have one you can grab bsd-mailx: sudo apt-get install unattended-upgrades apt-listchanges bsd-mailx -y ![]() Next we need to install the unattended-upgrades package and to ensure it sends emails the apt-listchanges package. My previous blog post covers how to do this with Postfix.Īs always, start off by making sure your apt list and existing packages are up-to-date: # Update the package list, update all packages and remove any packages that are no longer required sudo apt-get update -y & sudo apt-get dist-upgrade -y & sudo apt-get autoremove -y You’ll want to know when updates are being installed (or if they fail). The first thing to do before setting up automatic updates is to ensure your Raspberry Pi can send email. Any device that’s on your home network has the possibility of being a stepping stone for attackers if it can be easily breached. It seems a bit much to step away for 6 months from an absolutely minimal Ubuntu install and come back to a OS that can't update without modifying apt repo paths.Logging into machines and installing security updates periodically isn’t fun but for internet-exposed devices it’s important. While understandable repos won't be hosted super long, it would be very helpful if this migration could be recognized by the apt tool and the fix automatically suggested/applied. Sudo sed -i -r 's///g' /etc/apt/sources.listĪfter that you can run update, upgrade, and then do strongly consider release upgrade: sudo apt update sudo sed -i -r 's/(.)?//g' /etc/apt/sources.list Since OS updates are hosted by goodwill of mirrors they try to keep only newer versions hosted.īelow commands will edit your now out of date repo urls to the old-releases mirror - this worked from Impish -> Jammy and potentially for future versions as well. The repos for your OS version have removed from most mirrors (because the OS version has reached end of life). To be clear, I have auto-update turned on on the Ubuntu server and this happened recently (past week or 2).
