Specified network must be of type bridge

Hello,

I suddenly can’t boot multiple instances anymore. it shows the following error message

Failed start validation for device “eth0”: Specified network must be of type bridge

The instances are attached to a physical network “enp2s0” that I created with the incus-os tutorial “Directly attach instances to host network”. I used that network for weeks without problems

If I switch the network to the default bridge network “incusbr0”, I can boot the instance again. If I try to switch back to “enp2s0” I get the following error:

Invalid devices: Device validation failed for “eth0”: Specified network must be of type bridge

I would be happy for some help, thank you!

Apparently this is a bug: Invalid devices: Device validation failed for "eth-1": Specified network must be of type bridge · Issue #3155 · lxc/incus · GitHub
I should have looked on github before posting here, sorry.

Sadly I can’t get the temporary workaround working.
If I try:

devices:
  eth-1:
    nictype: bridged
    parent: enp2s0
    type: nic

I get the same error, when I try saving the configuration file.

@07359 Do you maybe have another NIC defined in a profile which also affects that instance?

I dont think so, the yaml only shows one configured

devices:
  eth-1:
    nictype: bridged
    parent: enp2s0
    type: nic
  eth-2:
    type: none
  eth0:
    type: none

Is that the incus config show --expanded output?

thank you for your help!

this is the whole output:

  root:
    path: /
    pool: local
    type: disk

the “parent: enp2s” is missing the “0” at the end, because I can’t save with the correct name “enp2s0” because then I get the error message
