Yesterday I flashed a new sd card (more space) for my rockpi-4b but after switching to the stable channel `armbian-config --cmd STABLE` the update keeps failing:

For now I am doing `sudo apt-mark hold armbian-firmware`.
Switching to rolling, updating there works (26.2.0-trunk.722). But the issue persists when switching back to stable.
As there have been recent changes https://github.com/armbian/firmware/pull/117 and https://github.com/armbian/firmware/pull/119 and I couldn't find other error reports on the forum, I guess this is an issue of the image packaging. 
I also plugged back in the old sd card and that system updated without issues.

And same on odroid m2

The same is happening to me on v26.2.1 for Banana Pi M5BananaPi M5 on debian trixie.

Solved it by simply removing the upstream folder which had some symlink tomfolery

1. rm -rf /lib/firmware/qcom/sm8550/ayn/

2. apt update && apt upgrade

3. PROFIT <3

Thank you @Revellion
I just did 
```
sudo apt-mark unhold armbian-firmware
sudo rm -rf /lib/firmware/qcom/sm8550/ayn/

sudo apt update && sudo apt upgrade
```
and it worked fine
