Comment 0 for bug 2023036

I'm running MAAS 3.2.7 with:

maas root boot-resources import

And I can my images get stuck importing at some random percentage on multiple MAAS redeployments. Moreover, in the gui I can only see one of the resources importing even though I have 3 of them:

$ maas root boot-source-selections read 1
Success.
Machine-readable output follows:

wget on images.maas.io works properly on the machine:
