Hello,
I had an issue where after some software updates the battery icon was gone after a reboot.
After requesting the status of upower I realized the service failed to launch
# systemctl status upower.service
× upower.service - Daemon for power management
Loaded: loaded (/usr/lib/systemd/system/upower.service; disabled; preset: disabled)
Active: failed (Result: exit-code) since Tue 2023-02-21 20:31:56 EST; 5min ago
Docs: man:upowerd(8)
Process: 3085 ExecStart=/usr/lib/upowerd (code=exited, status=127)
Main PID: 3085 (code=exited, status=127)

Feb 21 20:31:56 Inspiron systemd[1]: upower.service: Scheduled restart job, restart counter is at 5.
Feb 21 20:31:56 Inspiron systemd[1]: Stopped Daemon for power management.

Feb 21 20:31:56 Inspiron systemd[1]: Failed to start Daemon for power management.
Then after checking the dependencies/libraries I saw two of them being missing

So I went ahead and reinstall the libraries. The missing libraries were back specifically after re-building libimobiledevice, then # ldconfig and re-boot
