Ubuntu OS image options didn't show up and then did show up about rpi-imager HOT 15 CLOSED

ah, load balancing type stuff, got it.

from rpi-imager.

Works as expected, the OS options are defined in a .JSON file on our website,

http://downloads.raspberrypi.org/os_list_imagingutility.json

When you open the application it populates the list from these which can change dynamically

from rpi-imager.

Then what I'm telling you is that it didn't work.

I searched for that file in ~/.local and didn't find it. Where is the os_list_imagingutility.json file downloaded to?

from rpi-imager.

It isn't downloaded anywhere

from rpi-imager.

Well, it didn't work until after I installed the compiled version on the raspberrypi.org site... and then reinstalled the one I compiled. Why would that be?

from rpi-imager.

I'm guessing that Ubuntu was added to the list around the time you installed the version from raspberrypi.org

This happened within a 5 minute period... I had already downloaded the raspberrypi.org version previous to building from source. I had read this blog and thought I'd try it because it mentioned the Ubuntu OS options so it was already there.

I also had the OS selection window open for a minute or two because I'd never seen this app before and thought I missed something about where the Ubuntu OS options were so I looked into the "misc" option menu item and the "use custom" options. Surely it shouldn't have taken that long to get the json file.

it is doing it right now even...

Just shut down the app and restarted it and now the Ubuntu options are there..

from rpi-imager.

You're absolutely right. The author of the tool has just pointed out that some of our mirrors are out of sync and were serving up the old json file. You shouldn't be seeing that anymore, and I'll double check that everything is okay now.

from rpi-imager.

So within a few minutes the json file at specified in config.h was changing?

#define OSLIST_URL "https://downloads.raspberrypi.org/os_list_imagingutility.json"

I thinking there was a delay in file access and the application didn't wait and continued with just the defaults.

from rpi-imager.

This app looks to be populating the menu when it is opened.

Yes, you can end up at a different server each time with round-robin DNS configurations like this.
And yes, those servers should have the same files, but if anything is wrong, they may not.

cool, case closed. Thanks for keeping with me on this. Everyone wins.

If there's interest in expanding this apps capabilities... I make a script for doing what this app does but after loading the image onto the SD, I mount the partitions and adjust the wifi settings, hostname and locale/timezone. Very handy for headless setup.

Thanks again.
