Leia a mensagem "falha ao criar o soquete de escuta para 10.104.52.1: Endereço já em uso"
então escolha outro endereço IP, 10.104.52.2 ou algo assim
(Por favor, veja abaixo as atualizações 1, 2 e 3)
Hoje atualizei o sistema host e depois de uma reinicialização, o daemon LXD não é iniciado.
Dá o erro
failed to create listening socket for 10.104.52.1: Address already in use
O que posso fazer?
Eu tenho:
O comando que usei para iniciar
sudo systemctl start snap.lxd.daemon.service

A partir daqui, insira o loop infinito e nunca inicia
==================== UPDATE 3 ====================== =============
Eu tenho uma máquina física com o erro de loop de reinicialização do endlesse e uma máquina virtual que reinicia corretamente.
Na máquina física (com o erro durante o loop):

Isso pode ser relevante?
Leia a mensagem "falha ao criar o soquete de escuta para 10.104.52.1: Endereço já em uso"
então escolha outro endereço IP, 10.104.52.2 ou algo assim
Respondendo a mim mesmo RESOLVIDO
Eu instalei o bind9 na mesma máquina e isso tem precedência sobre o dnsmasq
