Battery monitor not working after upgrading ubuntu 21.04
See original GitHub issueI used the 20220109_v1.7.0_MiniPupper_V2_PS4_Ubuntu_21.10.0_Baseline.img.zip image.
The battery monitor was working. I could read the data from /sys/class/power_supply/max1720x_battery.
After installing I did a apt upgrade the battery monitor was no longer working.
During the upgrade a new kernel was installed (5.13.0-1015-raspi). The previous kernel was 5.13.0-1011-raspi.
It turns out that the max1720x_battery kernel module is not present in the new kernel.

@tech-life-hacking this issue is just on the device that upgrade the kernel .
Sorry, what I mention above, only for not apt upgrade. In my case, I installed some ROS packages and the battery monitor didn’t work, but it recovered correctly after running scripts above.
