Google System updates not working on Enterprise devices

[Johny]

Application device policy is set Automatic update but did not instal the system update automatically. Seems like that system update is downloading but not processing for the installation. As my app is on kiosk mode therefore there is no manual way to install the update. Application is running two user one is admin user and another is secondary user. 
1. Admin user 
2. Secondary

Device policy creating with the selection: 
pattern: String =

• "TYPE_INSTALL_AUTOMATIC"
• "TYPE_INSTALL_WINDOWED"
• "TYPE_POSTPONE"

fun mapToPatternToSystemUpdatePolicy(
pattern: String,
startTime: Int?,
endTime: Int?,
😞 SystemUpdatePolicy {
// Device update policy
 if (pattern.contains("TYPE_INSTALL_AUTOMATIC")) {
return SystemUpdatePolicy.createAutomaticInstallPolicy()
} else if (pattern.contains("TYPE_INSTALL_WINDOWED")) {
// Update windowed time is et minutes.
 if (startTime != null && endTime != null) {
return SystemUpdatePolicy.createWindowedInstallPolicy(
startTime,
endTime,
)
}
} else if (pattern.contains("TYPE_POSTPONE")) {
return SystemUpdatePolicy.createPostponeInstallPolicy()
}

return SystemUpdatePolicy.createAutomaticInstallPolicy()
}

Setup the policy in the :
val updatePolicy = DevicePolicyMapper.mapToPatternToSystemUpdatePolicy(
    systemUpdatePolicy,
    startTime,
    endTime,
)
dpm.setSystemUpdatePolicy(adminComponentName, updatePolicy)

What can be the causes pretty unclear to me.

It *should* interrupt any running process and perform the update. 

Could you attempt the same with Windowed instead? If it works, it'll be something disrupting the automatic install process; I'm expecting that with app updates in kiosk but not system normally.

[Johny]

I have tried with Windowed also. Doesn't work. System download the update but not able to install automatically.  

[jasonbayton]

Just to clarify are you talking about OEM system updates or Google (play) system updates? The latter it is expected and is reasonably new behaviour, the former would need logs to understand what's not working properly

[Johny]

I am looking for Android system update like Android 13 has released for Android 12 devices. I can see from the settings that system update is ready to download and install. [installation process should work as automatic when new release is available]. 

[jasonbayton]

Ok then yeah debug logs - a bug report - would offer some insight into what's going on.

We also see that our devices connected via mobile data also doesn't do an update.

Have you tried that connected to a Wifi?

[Johny]

Yes, device is connected with WIFI and admin. Device is downloading the update not able to install automatically. If there is issue with the internet issue in that case device will not able to download the update.

I fully agree.
