树莓派安装 ubuntu 20.04 LTS 碰壁指南

树莓派安装 Ubuntu 20.04 LTS 碰壁指南

1.镜像下载与烧录

镜像下载地址:https://cdimage.ubuntu.com/releases/20.04.1/release/ubuntu-20.04.1-preinstalled-server-arm64+raspi.img.xz

SD Card Formatter

Win32DiskImager

2.启用root账户

输入命令后根据提示操作

su passwd root

3.无线网络连接初始化

进入netplan配置文件夹

cd /etc/netplan/

配置无线网

sudo vim 50-cloud-init.yaml

配置如下，仅供参考

# 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:
ethernets:
eth0:
dhcp4: true
optional: true
version: 2
wifis:
wlan0:
dhcp4: true
optional: true
access-points:
"你的无线网络名称":
password: "123456789"

注意在冒号后面，记得要有个空格或者换行
启用配置

sudo netplan try
sudo netplan apply
systemctl daemon-reload

4.更换树莓派国内镜像源

sudo vim /etc/apt/sources.list

我全部更换为阿里镜像源，最终配置如下

##     or do the same in user-data
## b.) add sources in /etc/apt/sources.list.d
## c.) make changes to template file /etc/cloud/templates/sources.list.tmpl

刷新镜像源

source source.list
apt get update
apt get upgrade

4.启用SSH（*）

sudo apt install openssh-server

ufw allow ssh

尝试一下用默认账户连接(我尝试失败，您可以一试)

sshd_config

sudo vim /etc/ssh/sshd_config

/PermitRootLogin

LoginGraceTime 2m
