DHCP issue after upgrade to MAAS 3.7

I’ve recently had to update Ubuntu from 22.04 LTS to 24.04 LTS. After the update I also went ahead and updated MAAS from v3.3 to v3.7 (Debian packages). However, since then I have problems with the DHCP configuration.

So far, I’ve figured out, that /var/lib/maas/dhcpd-interfaces and the respective dhcpd_.conf are all empty. On each restart, the maas-dhcpd_.service fails, because the dhcpd_.conf files are initially missing.

On the Web UI, everything looks good. I have a fabric with VLANs and subnets defined. For some MAAS manages DHCP.

I can’t find a reason, why MAAS doesn’t pick up the DHCP configuration. Any help in troubleshooting this problem is highly appreciated. :pleading_face:

There were a bunch of DHCP-related bugs in 3.7.0 that are waiting to be released in 3.7.1 (ETA next days/early next week) 3.7.x : MAAS

I’d suggest to try 3.7/edge

Thank you r00ta for the quick response. There isn’t a Debian package release for 3.7/edge, is there?

I am not sure whether this problem has been fixed because I have some clusters affected with this bug and haven’t been fixed after upgrading to 3.7.1.

@osmanlicilegi Unfortunately, I cannot provide feedback yet. I’m waiting for the next maintenance window to install the update. I’ll keep you posted.
