In FCE deployment, when changing the bootsources from the default “http://images.maas.io/ephemeral-v3/daily”, it might still trying to fetch the bootsources from that url. And running that in an airgapped environment can have even worse consequences.
It should cancel import when changing (maas boot-resources stop-import), when changing the boot sources (eg. with maas boot-source update 1 url=“http://offline.repo/maas/” and re-initiate it with the updated config.

such as? I mean I expect it to fail, but what are the ‘even worse’ consequences that you allude to?
if you have firewall dropping the requests, it will just stay stuck there trying to fetch the image, but no response will come. Basically the connection is open, pending forever.
I didn’t mean even worse as the universe will suffer.
