Public bug reported: Call trace occurred every time when running `netplan apply` after a wrong wireless interface was once described in the yaml.
System: Intel NUC7PJYH Image: Ubuntu Core 20 beta daily build (20200514.2) Steps to Reproduce: 1. On this Intel NUC7PJYH I tested, its wireless interface is wlo2 instead of wlan0, I mistakenly described the wireless interface as wlan0 in the yaml at the first time, corrected it to wlo2 as far as I found the wireless connection is unreachable. 2. After the wireless interface was corrected to wlo2, following call trace happened every time running `netplan apply`: $ sudo netplan apply Failed to start netplan-wpa-wlan0.service: Unit netplan-wpa-wlan0.service not found. Traceback (most recent call last): File "/usr/sbin/netplan", line 23, in <module> netplan.main() File "/usr/share/netplan/netplan/cli/core.py", line 50, in main self.run_command() File "/usr/share/netplan/netplan/cli/utils.py", line 179, in run_command self.func() File "/usr/share/netplan/netplan/cli/commands/apply.py", line 46, in run self.run_command() File "/usr/share/netplan/netplan/cli/utils.py", line 179, in run_command self.func() File "/usr/share/netplan/netplan/cli/commands/apply.py", line 173, in command_apply utils.systemctl_networkd('start', sync=sync, extra_services=netplan_wpa) File "/usr/share/netplan/netplan/cli/utils.py", line 86, in systemctl_networkd subprocess.check_call(command) File "/usr/lib/python3.8/subprocess.py", line 364, in check_call raise CalledProcessError(retcode, cmd) subprocess.CalledProcessError: Command '['systemctl', 'start', '--no-block', 'systemd-networkd.service', 'netplan-wpa-wlo2.service', 'netplan-wpa-wlan0.service']' returned non-zero exit status 5. 3. When a call trace happened, the wireless could still connect to the AP without problem. When system connected to the AP described in yaml, it still has the ability get an IP from it and ping the gateway on AP. ** Affects: netplan.io (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1878926 Title: Call trace occurred after a wrong wireless interface mistakenly applied once in the yaml To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/netplan.io/+bug/1878926/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
