Unable to restart device after update from web page or REST API

[Maxwell Pung]

Hello,

I am using SWUpdate 2024.05 commit 3a333f4b4b1cec5e3cb1f2e3da41ad82735d0242. I am finding that after a doing an update (performed via web page or rest API), I am unable to restart the device.

When I click the Restart System button in the top right corner of the web page, a modal dialog box will pop up for a short while (10 seconds maybe) saying "The system will restart. Please be patient, as restarting takes about one minute." Then the dialog box disappears and the system does not restart.

When I issue a restart command via the REST API with command curl -X POST --data "" http://foobar:8080/restart I get the response Device will reboot now. But the system does not restart.

Any time I issue one of these commands or attempt to restart via web page the swupdate service prints a new line to it's log:

Aug 27 15:24:47 <machine> swupdate.sh[361]: [DEBUG] : SWUPDATE running :  [postupdate] : Running Post-update command

In the docs there is a snippet about the restart REST API endpoint:

"If configured (see post update command), this request will restart the device."

I take this to mean you need CONFIG_SCRIPTS=y, which I do have. My interpretation of this could very well be wrong. I will share my runtime cfg file as well in case the issue is there:

globals :
{
verbose = true;
loglevel = 5;
syslog = true;
public-key-file = "/etc/public-key-for-signed-updates.pem";
};

webserver :
{
document_root = "/www";
userid        = 0;
groupid       = 0;
};

What am I missing or not understanding?

Does it help if you pass "-p /sbin/reboot" to SWUPDATE_ARGS?

If I extend my swupdate.cfg with postupdatecmd = "/usr/sbin/reboot"; in the globals sections then it will reboot automatically after an update is performed. Regardless of whether that update is performed via cli, REST API or web page.

This behavior does not fit my use case. It would be preferable to not reboot automatically after the update is finished but independently, at a later time, using something like curl -X POST --data "" http://foobar:8080/restart or the Restart System button on the web page.

I am able to get desired behavior by adding postupdatecmd = "/usr/sbin/reboot"; to the globals section of swupdate.cfg and adding run-postupdate = false; to the webserver section. Restarting system via REST API and web page work with this configuration.

Right, this is the correct configuration for your use case.
