Public bug reported:
24.04 nightly, downloaded Mar 5.
network-manager 1.45.90-1ubuntu1
In network manager, if you try to set ipv6.token, when you save it says
Error: connection verification failed: ipv6.token: only makes sense with
EUI64 address generation mode
This is the same as under 22.04. However under 22.04 the solution is
setipv6.addr-gen-mode eui64 along with the token. In 24.04 when you save
you get
Error: Failed to save 'netplan-enp3s0'
(6effa1b1-280b-3785-9b52-c723b445fb3e) connection: failed to update
connection: netplan: YAML translation failed: Error in network
definition: enp3s0: ipv6-address-generation and ipv6-address-token are
mutually exclusive
There doesn't seem to be any combination involving the token that works.
