Public bug reported:
Using Ubuntu Server 24.04 LTS
After upgrading my packages, including Netplan (using "apt dist-upgrade") and
rebooting, network configuration (netplan yaml file) was no longer applied to
the server.
I noticed some changes related to file/directory permissions in
/etc/netplan, but changed them to stop showing warnings.
I'm talking about the new versions 1.0-2ubuntu1.1 and/or 1.0-2ubuntu1.2 (both
came out within 3 days, so I don't know which of the two is responsible for the
relevant changes)
But only a rollback to the 4 "netplan"-packages(libnetplan1 netplan.io
netplan-generator python3-netplan) from LTS version 1.0-2ubuntu1 "solved" the
problem. My configuration is applied again on boot.
My config:
network:
version: 2
renderer: networkd
ethernets:
enp4s0:
dhcp4: false
enp6s0:
dhcp4: false
enp9s0:
