[Bug 2097769] Re: Installation of ubuntu-desktop-minimal breaks DNS
#19 might work in some scenarios, but not in all cases.
@aph3rson If you're using Ubuntu autoinstall, I decided to just install
ubuntu-desktop-minimal at that stage before our Puppet takes over. It
avoids this issue, but does mean we need a separate autoinstall user-
data for desktop and server builds

Title:
Installation of ubuntu-desktop-minimal breaks DNS
Status in netplan.io package in Ubuntu:
Triaged
Status in systemd package in Ubuntu:
Won't Fix
Bug description:
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.
