GrapheneOS
"Unable to fetch list of apps" not handled gracefully for DNS or Network errors
I am frequently with no WiFi/Cellular and have the GrapheneOS Apps updater checking during these periods.
I frequently get a notification that Apps was "Unable to fetch list of apps" along with the error java.net.UnknownHostException: Unable to resolve host "apps.grapheneos.org"...
Would it be possible to have this error be handle gracefully, so that when offline Apps will just silently fail to check for updates?
Many thanks for your time
Are you using a VPN? It seems that some of them falsely claim that device is online when it isn't, or isn't yet.
I'm not using a VPN, but i think this might occur when switching between WiFi networks. I did also discover you can disable the notification channel "Background update check failed" but I still think java.net.UnknownHostException shouldn't notify.
@dm-canteen Switching between Wi-Fi networks will trigger the OS considering internet temporarily unavailable including stopping jobs.
You probably want to know if your network is broken.
It could indeed be broken, but if so it's the default behavior of my router(s) and Graphene when switching. If I immediately tap the notification and then check for updates it goes through fine. It seems the job is run after re-connecting but my network isn't actually ready; a la:

Feel free to close if you think it's just a quirk of my setup
@dm-canteen Are internet connectivity checks enabled in Settings -> Network & internet -> Internet connectivity checks ?
I've reproduced this issue by disabling internet connectivity checks, connecting to a Wi-Fi network with no internet access and then running the UpdateCheckJob: adb shell cmd jobscheduler run app.grapheneos.apps 1001
It's an expected consequence of internet connectivity checks being off if they're off.
Yes, they are enabled and set to the GrapheneOS servers. I also noticed PrivateDNS was set to Automatic, which I have just changed to Off.
@Sfcyber
Me too.

If your VPN is causing the issue, it implies that the VPN is not properly reporting when it's up or down.
How to solve. That's the message I get.
Unable to download Vanadium: Unable to resolve the server name.
Details: java.net.UnknownHostException: Unable to resolve host "apps.grapheneos.org": No address associated with hostname
@Sfcyber Your network isn't allowing resolving the apps.grapheneos.org domain name. You'll need to fix that.
My network? Just now the webview has been updated, only Vanadium does not update.
Yes, this error means that your network isn't working correctly. It means it can't correct to apps.grapheneos.org because it can't resolve the name to an IP via DNS. This is an issue with your DNS or network connection.

It's an issue with your network. If you're using a VPN, it's an issue with the VPN. If you're not, it's an issue with the mobile data or Wi-Fi connection depending on which you're using.
Does not appear to be a bug. There isn't really much that can be done to work around this in Apps as far as we can tell.

OK, I'm going to make some changes here, then I'll let you know here. Thanks
