Dec 23, 2023 • 1 min read

I'm continuing to work through upgrading all of my Debian virtual machines.

Upgrade PH-01

Steps performed on PH-01

cat /etc/os-release
- PRETTY_NAME="Debian GNU/Linux 11 (bullseye)"
sudo apt-mark showhold
sudo apt update
- 3 packages can be upgraded.
sudo apt upgrade
sudo apt full-upgrade
sudo apt autoremove
sudo nano /etc/apt/sources.list
- I replace each instance of bullseye with bookworm
sudo apt update
sudo apt upgrade
Restart services during package upgrades without asking? Yes
sudo apt full-upgrade
sudo apt autoremove
sudo reboot
cat /etc/os-release
- PRETTY_NAME="Debian GNU/Linux 12 (bookworm)"

Steps performed on AUTHENTIK-01

cat /etc/os-release
- PRETTY_NAME="Debian GNU/Linux 11 (bullseye)"
sudo apt-mark showhold
sudo apt update
- 4 packages can be upgraded.
sudo apt upgrade
sudo apt full-upgrade
sudo apt autoremove
sudo nano /etc/apt/sources.list
- I replace all instances of bullseye with bookworm
sudo apt update
sudo apt upgrade
Restart services during package upgrade without asking? Yes
sudo apt full-upgrade
sudo apt autoremove
sudo reboot
cat /etc/os-release
- PRETTY_NAME="Debian GNU/Linux 12 (bookworm)"

Authentik is functioning properly after the upgrade.

Steps performed on BOOKSTACK-01

cat /etc/os-release
- PRETTY_NAME="Debian GNU/Linux 11 (bullseye)
sudo apt-mark showhold
sudo apt update
- 21 packages can be upgraded.
sudo apt upgrade
sudo apt full-upgrade
sudo apt autoremove
sudo nano /etc/apt/sources.list
- I replace all instances of bullseye with bookworm
sudo apt update
sudo apt upgrade
Restart services during package upgrade without asking? Yes
sudo apt full-upgrade
sudo apt autoremove
sudo reboot
cat /etc/os-release
- PRETTY_NAME="Debian GNU/Linux 12 (bookworm)"

Bookstack is working after the upgrade.

Since this is such a slow process to work through I'm probably going to have to work on tackling a few machines each day.
