Hi, the image you have is using a broken snap seed in the image. Can you try a newer daily image?

Would doing a system update fix it, or do I have to re-download a newer daily build iso image?

removing and reinstalling the snapd package should fix it

Removed it via ‘purge’ option, did a full update, and installed it back. Worked. Thanks.
