I got a PXE server that was able to netboot Debian 9.5. I wanted to start playing with Buster/Sid, and completely forgot how to convert the machine.
For more information on Sid, check out here. But the most relevant thing about it is this:
The Unstable repositories are updated every 6 hours. You can upgrade with apt-get dist-upgrade, taking all the necessary precautions beforehand of course.
I did some googling and found this page on how to do it, but figured I’d capture it for myself here.
Make sure that your Debian 9.5 machine is as up to date as possible:
NOTE: you need to be root for all of this.
apt-get update apt-get upgrade apt-get dist-upgrade
Next, convert the
sed -i 's/stretch/buster/g' /etc/apt/sources.list
apt cache with the new sources.
Update the machine fully:
apt-get upgrade apt-get dist-upgrade
Verify that the update has succeeded:
cat /etc/debian_version buster/sid
I’d reboot now to make sure everything comes up as expected.
