I ran an apt upgrade this morning, and now battery monitoring seems broken.
upower doesn’t even list the battery anymore:

You were on rk3588 pocket reform with Debian unstable, right?
Instead of telling you to run some commands I’d like you to try out some improvements to reform-check which might uncover what’s going on (and then maybe this can also help others automatically in the future). I created this MR:
Context: I encountered an issue during an apt upgrade this morning which left apt in a broken state. I tried to resolve this by uninstalling and reinstalling the latest kernel package. At least the inconsistent apt state was resolved after that.
I see the Sub-process /usr/bin/dpkg returned an error code in your log but I assume this is due to errors with the dkms module which is incompatible with kernel 6.17 from backports? Or was there a different problem? If you already closed the terminal, you can find the answers in /var/log/apt/term.log.

Indeed, this problem will be fixed in the reform-tools version scheduled for upload to trixie-backports. Running reform-check would’ve also told you that this is the problem. Or you tell me if it does not because then I have to fix it.
E: linux-headers-mnt-reform-arm64 is not installed -- cannot compile reform2_lpc module
E: reform2_lpc is not loaded (battery status information will be missing)
E: /usr/lib/modules/6.17.8+1-mnt-reform-arm64/updates/dkms/reform2_lpc.ko{.xz} does not exist
E: the linux header package linux-headers-6.17.8+1-mnt-reform-arm64 for the currently running kernel is not installed
