** Description changed: Summary ======= Issue observed using 20200422 images focal-preinstalled-server-arm64+raspi.img.xz and focal-preinstalled-server-armhf+raspi.img.xz on: - Rapsberry Pi 4 4GB - Rapsberry Pi 3B When setting up Wireless network via netplan config on a Raspberry Pi 4 4GB with Ubuntu Server 20.04, the settings are not taken into account until the device is rebooted, because the service created (netplan-wpa- wlan0.service) is in a "inactive (dead)" state. A workaround is to manually restart the service after applying netplan configuration $ sudo netplan apply $ sudo systemctl restart netplan-wpa-wlan0.service This should be done automatically when a new netplan configuration is applied. + + SRU acceptance criteria + ======================= + + The netplan package is generally covered by an SRU exception, so general + testing should suffice. That being said, the fix can be verified + explicitly by making sure that WiFi configuration still works: using the + -proposed packages on a WiFi-enabled device, craft a netplan yaml config + enabling wifi and apply the config with `netplan apply`. Wireless should + now be working correctly without any other manual steps. + Steps to reproduce ================== 1. Install Ubuntu Server 20.04 image (focal-preinstalled-server-arm64+raspi.img.xz) on a Raspberry Pi 4 4GB (I haven't tested with Ubuntu Server on other devices). 2. Connect a screen and a USB keyboard, or connect to the device via serial console (UART). 3. By default, the device is not connected to the network yet: $ ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000 link/ether dc:a6:32:57:b9:ba brd ff:ff:ff:ff:ff:ff 3: wlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000 link/ether dc:a6:32:57:b9:bb brd ff:ff:ff:ff:ff:ff $ networkctl IDX LINK TYPE OPERATIONAL SETUP 1 lo loopback carrier unmanaged 2 eth0 ether no-carrier configuring 3 wlan0 wlan off unmanaged 3 links listed. 4. Create a netplan config file to match your WiFi router config and copy it to /etc/netplan/: $ cat lab.yaml network: version: 2 wifis: wlan0: access-points: ubuntu-cert-wpa: password: myp455w0rd dhcp4: yes $ sudo cp lab.yaml /etc/netplan/ 5. Apply the new configuration: $ sudo netplan apply In journalctl: Apr 23 03:57:38 ubuntu systemd[1]: systemd-networkd-wait-online.service: Succeeded.

I then found there is a `netplan-wpa-wlan0` systemd service that is "inactive". Restarting it, the connection process happens, the device gets an IP from the DHCP server (my WiFi router), and I can ping the gateway and the outside: $ sudo systemctl status netplan-wpa-wlan0.service ● netplan-wpa-wlan0.service - WPA supplicant for netplan wlan0 Loaded: loaded (/run/systemd/system/netplan-wpa-wlan0.service; enabled-run> Active: inactive (dead) $ sudo systemctl restart netplan-wpa-wlan0.service Apr 23 04:01:25 ubuntu wpa_supplicant[1752]: Successfully initialized wpa_supplicant Apr 23 04:01:28 ubuntu wpa_supplicant[1752]: wlan0: Trying to associate with SSID 'ubuntu-cert-wpa' Apr 23 04:01:30 ubuntu wpa_supplicant[1752]: wlan0: CTRL-EVENT-ASSOC-REJECT bssid=00:00:00:00:00:00 status_code=16 Apr 23 04:01:33 ubuntu wpa_supplicant[1752]: wlan0: Trying to associate with SSID 'ubuntu-cert-wpa' Apr 23 04:01:35 ubuntu systemd-udevd[760]: Network interface NamePolicy= disabled on kernel command line, ignoring.
