Can't start LXD containers with IPv6 routed


Today I wanted to patch and reboot the containers, but unfortunately they don’t start anymore.


Tried to detach the default, but without success.
lxc network detach lxdbr0 webserver default

I’m using:
lxc config device add webserver eth0 nic nictype=routed ipv6.address=IPv6 on the container

This problem only affects the IPv6 containers with nictype=routed.

lxd 4.21 22114 latest/stable canonical✓

Looks like the same issue as:

The workaround until the fix is published is to set:

lxc config device set <instance> <device> ipv{n}.gateway=none
