This will be fixed soon.

I started from scratch. Installed Armbian_25.2.2_Rpi4b_bookworm_current_6.12.15_minimal.img Having in mind what @eselarm suggested as culprit, I put raspi-firmware on hold root@rpi5b:~# apt-mark hold raspi-firmware then dpkg --remove --force-all libraspberrypi0 armbian-bsp-cli-rpi4b-current apt --fix-broken install apt install armbian-bsp-cli-rpi4b-current everything OK apt upgrade everything OK Reboot root@rpi5b:~# uname -a Linux rpi5b 6.12.31-current-bcm2711 #1 SMP PREEMPT Wed Jun 4 14:00:53 UTC 2025 aarch64 GNU/Linux Tried the same with raspi-firmware unhold and got this . .

Then I installed Armbian_25.2.4_Rpi4b_bookworm_current_6.12.22_minimal.img First thing after boot: root@rpi4b:~# update-initramfs -u update-initramfs: Generating /boot/initrd.img-6.12.22-current-bcm2711 ERROR: Unsupported initramfs version (6.12.22-current-bcm2711) The same with Armbian_25.5.1_Rpi4b_bookworm_current_6.12.28_minimal.img I don't have anymore a clean 25.2.3 but the homeassistant_minimal.img one has the same problem. No idea how to fix it. raspi-firmware has status optional and the 25.2.2 works OK without it, I think I will go this way hoping somebody with better skills then me will fix it one day.

Wow, that was fast! But what about ipv6? It works on the community image for opi-PC2 as I mentioned but not here.. Edit. Nvm, I see there is a cmdline.txt file in there.. Thank you for the fast reply!

I tried to set the I2C interface with the armbian-config option but it doesn't work because it writes to the file: armbianEnv.txt .... overlays=sun50i-h6-i2c0 sun50i-h6-i2c1 sun50i-h6-i2c2 and it didn't work on my OrangePi3LTS and it doesn't start the i2C service on startup? but when I enter it manually: overlays=i2c0 i2c1 i2c2 then the i2c service works with my 40x2 LCD 🙂 ...is this a bug and if so can it be fixed? is the option: armbian-config still compatible with my OrangePi3 LTS?

docs don't apply for rpi family since it uses proprietary boot way. Upstream howtos for editing /boot/firmware/config.txt apply. dtoverlay=disable-bt dtoverlay=disable-wifi
