I also upgraded from bookworm to trixie and saw this warning. I can confirm that Igor's suggested workaround addresses it: wget https://apt.armbian.com/armbian.key gpg --dearmor < armbian.key | sudo tee /usr/share/keyrings/armbian.gpg > /dev/null apt is now happy with the armbian repo.

I flashed same image to a SD card and tried to boot from it. Following is the result of `grep mmcblk1p2 /var/log/syslog` 2025-09-17T09:52:44.015489+00:00 rock-5-itx armbian-resize-filesystem[947]: ### [resize2fs] Trying to resize ext4 filesystem on /dev/mmcblk1p2: 2025-09-17T09:52:44.015493+00:00 rock-5-itx armbian-resize-filesystem[947]: Running 'resize2fs /dev/mmcblk1p2' now... 2025-09-17T09:52:44.015508+00:00 rock-5-itx armbian-resize-filesystem[947]: Filesystem at /dev/mmcblk1p2 is mounted on /; on-line resizing required 2025-09-17T09:52:44.021891+00:00 rock-5-itx kernel: EXT4-fs (mmcblk1p2): mounted filesystem with writeback data mode.

many thanks, JMCC but I couldn't, for the life of me get it to install. After trying to install whatever armhf .deb files I could, I got stuck with 3 missing deps. After more fiddling and basically copying every possible deb file to the apt cache, somehow I made it worse. I give up for today, it's been a couple of hours after my dayjob already. Wanted to use the tinkerboard a video streamer/lite computer for the bedroom but without acceleration for youtube, netflix and even my own movies, might as well get one of those crappy android sticks. I'm affraid that without some automagic script to run it all I'm lost this is what I succeded in getting: The following packages have unmet dependencies: media-buster-legacy-tinkerboard : Depends: qtmultimedia5-examples but it is not going to be installed Depends: qtgstreamer-plugins-qt5 but it is not going to be installed Depends: kodi-rk but it is not installable Depends: mpv-legacy but it is not installable Depends: librga2 but it is not installable

Sorry, it's working now.

Hi, In the documentation (https://docs.armbian.com/Developer-Guide_User-Configurations/#user-provided-kernel-config) it says: "User provided kernel config: If the file userpatches/linux-$LINUXFAMILY-$BRANCH.config exists, it will be used instead of the default one from config." Is there a way to define only the desired changes to the kernel parameters?
