I had a machine in MAAS which I deployed. After deployment, I manually installed maas-rack-controller and pointed it to the Region Controller, so a new rack appeared.
I tried to delete this new rack controller and came across this error in the UI:
The delete action for 1 controller failed with error: ("Cannot delete some instances of model 'VLAN' because they are referenced through a protected foreign key: 'PhysicalInterface.vlan'", [<PhysicalInterface: name=usb0, type=physical, mac=00:0e:c6:88:b7:9f>, <PhysicalInterface: name=enp0s25, type=physical, mac=b8:ae:ed:7d:17:d2>, <PhysicalInterface: name=enp0s25, type=physical, mac=b8:ae:ed:7d:16:d0>, <PhysicalInterface: name=enp0s25, type=physical, mac=b8:ae:ed:7c:4d:75>, <PhysicalInterface: name=enp0s25, type=physical, mac=b8:ae:ed:7e:b4:99>])

I had a machine in MAAS which I deployed. After deployment, I manually installed maas-rack-controller and pointed it to the Region Controller, so a new rack appeared.
Then I configured this rack controller as secondary rack controller for a VLAN.
Finally, I tried to delete this new rack controller and came across this error in the UI:
The delete action for 1 controller failed with error: ("Cannot delete some instances of model 'VLAN' because they are referenced through a protected foreign key: 'PhysicalInterface.vlan'", [<PhysicalInterface: name=usb0, type=physical, mac=00:0e:c6:88:b7:9f>, <PhysicalInterface: name=enp0s25, type=physical, mac=b8:ae:ed:7d:17:d2>, <PhysicalInterface: name=enp0s25, type=physical, mac=b8:ae:ed:7d:16:d0>, <PhysicalInterface: name=enp0s25, type=physical, mac=b8:ae:ed:7c:4d:75>, <PhysicalInterface: name=enp0s25, type=physical, mac=b8:ae:ed:7e:b4:99>])
