Public bug reported:
After performing an autoinstall with Ubuntu Server ISO and rebooting,
trying to automate the installation of ubuntu-desktop-minimal causes DNS
settings to be lost.
For our specific use-case, we are installing ubuntu server (fully automated),
then using Puppet to install desktop packages. This was working without any
manual interaction previously on both Ubuntu 22.04 and 24.04
For the last week or so, deployments of 24.04 (22.04 is still fine) are getting
stuck after installing ubuntu-desktop-minimal. The DNS server settings are
lost, but IP connectivity remains.
Step-by-step
1) Install Ubuntu Server with default network configuration using autoinstall.
2) Reboot and install network-manager (note that everything is still working
normally)
3) Install ubuntu-desktop-minimal
DNS settings are now lost on the primary interface, yet IP connectivity
remains. networkd is still managing the interface, but "netplan get"
reports that NetworkManager is the current renderer.
```
network:
version: 2
renderer: NetworkManager
ethernets:
enp1s0:
critical: true
nameservers:
addresses:
- 172.16.1.100
- 172.18.1.100
dhcp-identifier: "mac"
dhcp4: true
```
We can workaround the problem forcing an extra reboot after installing
ubuntu-desktop-minimal. But previously this workflow was fine without rebooting
until the very end of the config.
