Title:
/usr/sbin/on_ac_power incorrectly reporting ac power status
Status in powermgmt-base package in Ubuntu:
Confirmed
Status in powermgmt-base source package in Kinetic:
Confirmed
Bug description:
Good afternoon, folks.
I believe I discovered a bug in the /usr/sbin/on_ac_power script. I
have a Dell OptiPlex 5090 host that has an entry in
/sys/class/power_supply for "ucsi-source-psy-USBC000:001". I believe
this is the USB-C power delivery port on the front of the chassis. The
issue I'm encountering is that /usr/sbin/on_ac_power is exiting with
code 1 which states: (1 (false) if not on AC power) when that isn't
the case.
This looks to be because of the ucsi-source-psy-USBC000:001 entry
reporting the "online" status as 0, presumably because nothing is
currently connected to that USB-C port.
This causes /usr/sbin/on_ac_power to incorrectly report that the
machine isn't connected to AC power and causes other utilities like
unattended-upgrades to quit when using the default configuration since
it believes the machine isn't connected to AC power.
There is a workaround with unattended-upgrades where you can specify
it to run regardless of if AC power is connected, but as more and more
chassis implement power-delivery USB-C ports I foresee this becoming
more of an issue.
I'm not sure if it's anything to look into, but I figured I would
share my findings. Please let me know if you have any questions or if
I can provide any additional information, troubleshooting, or testing.
Thanks!
