Does it show something after the upgrade?
sudo cat /sys/class/dmi/id/product_uuid

dmbaturin subscribed.Oct 3 2025, 11:31 AM

@immtelecom It looks like the assumption that product UUID is always available is incorrect. Out of curiosity, what kind of a machine is it? Could you show us the output of show version?

I found the same issue on KVM machines spawned with qemu-kvm by hand but I wonder where else there's no product UUID.

Proposed fix: https://github.com/vyos/vyos-1x/pull/4774

dmbaturin edited projects, added VyOS 1.5 Circinus (2025.11); removed VyOS 1.5 Circinus (1.5-stream-2025-Q3), VyOS Rolling.
dmbaturin changed Is it a breaking change? from Unspecified (possibly destroys the router) to Perfectly compatible.
