尝试配置时出现的Netplan错误
尝试配置时出现的Netplan错误
提问于 2021-09-15 16:45:04
我正在远程 Raspberry Pi 4上运行Ubuntu服务器20.04.3LTS。它通过WiFi连接到一个远程路由器(IP 192.168.1.1)，并且我已经用netplan配置了网络。然而，几个月后，我决定更改DNS配置，即删除我的路由器本地DNS，并将其替换为Cloudflare的DNS。因此，知道yaml文件对空格非常敏感，我所做的唯一更改就是删除"92“和"68"，因此文件现在如下：
$ cat /etc/netplan/50-cloud-init.yaml
# This file is generated from information provided by the datasource. Changes
# to it will not persist across an instance reboot. To disable cloud-init's
# network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
network:
version: 2
renderer: networkd
ethernets:
eth0:
dhcp4: true
wifis:
wlan0:
dhcp4: no
addresses: [192.168.1.12/24]
gateway4: 192.168.1.1
nameservers:
addresses: [1.1.1.1, 8.8.8.8]
access-points:
"accesspointname":
password: "accesspointpassword"
version: 2然而，当我运行netplan尝试时，我会得到以下内容：
$ sudo netplan try
Job for netplan-wpa-wlan0.service canceled.
An error occurred: Command '['systemctl', 'stop', 'systemd-networkd.service', 'netplan-wpa-*.service']' returned non-zero exit status 1.
Reverting.
Warning: Stopping systemd-networkd.service, but it can still be activated by:
systemd-networkd.socket另外，有时我会得到以下错误：
$ sudo netplan try
Job for netplan-wpa-wlan0.service canceled.
An error occurred: Command '['systemctl', 'stop', 'systemd-networkd.service', 'netplan-wpa-*.service']' returned non-zero exit status 1.
Reverting.

During handling of the above exception, another exception occurred:

raise CalledProcessError(retcode, cmd)
subprocess.CalledProcessError: Command '['systemctl', 'stop', 'systemd-networkd.service', 'netplan-wpa-*.service']' returned non-zero exit status 1.我希望对此非常小心，因为我不希望在网络配置错误的情况下被永久地锁在门外，因为我没有本地访问权限来修复需要的东西(这就是为什么我运行netplan尝试。我不确定是否重新启动系统，是否会被锁在门外？)有什么建议吗？

看看这有什么区别..。
注意：确认没有制表符，只有空格
注：普通缩进是两个空格
network:
version: 2
renderer: networkd
ethernets:
eth0:
dhcp4: true
optional: true
wifis:
wlan0:
addresses: [192.168.1.12/24]
gateway4: 192.168.1.1
nameservers:
addresses: [1.1.1.1, 1.0.0.1]
access-points:
"accesspointname":
password: "accesspointpassword"并创建/etc/cloud/cloud.cfg.d/99-disable-network-config.cfg...
network: {config: disabled}然后..。
sudo netplan try
等你准备好了。
sudo netplan generate
sudo netplan apply
reboot
