前言

每天打开我的Ubuntu，就好像开盲盒一样，你永远不知道他的网路到底好着没。

---

网络问题

果不其然，今天打开ubuntu，又又又又又没有网络标识。

无论我怎么改变网络适配器的网络连接方式，无论是桥接模式还是NAT模式，都没有网络表示。

---

原因分析：

想都不用想，肯定是没有网络连接的。
ifconfig只能找到本地环回

ping一下肯定也是不行的
无论ping域名还是ping ip都不行

---

解决方案：

几个还算有效的方法分享一下

1 重启网络

1.1 启动网络服务并输入密码

sudo systemctl start NetworkManager

1.2 重启网络服务

sudo systemctl restart NetworkManager

---

2 可能是Ubuntu的NetworkManager有问题（80%的问题都是他）

2.1 进入root并输入密码

sudo su

2.2 更新NetworkManager的配置

得先有gedit或者vim，两个随意一个，这里用的gedit，没有就先弄gedit，有的话直接下一步

apt-get install gedit

用gedit打开NetworkManager.conf

gedit /etc/NetworkManager/NetworkManager.conf

将第五行 managed=False 改为 managed=True ，然后 ctrl+s 保存后退出

如果本身就是True就不用改了。

2.3 删除NetworkManager配置

service NetworkManager stop
rm /var/lib/NetworkManager/NetworkManager.state 
service NetworkManager start 

注意看桌面左上角状态来会自动恢复网络连接的，会出现图标。

2.4 重启即可恢复网络标识

---

3 VM设置

将vm中网络适配器从NAT模式换为桥接模式，或者桥接模式换为NAT模式。

---

别忘了之后重启一下vm！

总结

相信总有一款适合你，我的ubuntu也好了。
网络标识也出来了。

前奏：文中的绝大多数情况都是因为服务器没有网络服务，如果读者的电脑有完全的网络服务可能参考意义不是很大。不过，处理的方法和排查的思路可以作为一个借鉴。

#尝试重启大法：

另外一台服务器尝试新建虚拟机

重新作了一台类似的虚拟机之后OK
先安装：
./A300-3010-npu-driver_20.2.0_ubuntu18.04-x86_64.run --install-username=ubuntu --install-usergroup=ubuntu --full
接着安装：
./A300-3000-3010-npu-firmware_1.76.22.3.220.run --install-username=ubuntu --install-usergroup=ubuntu --full

本台服务器新建虚拟机

 

#安装到90%的时候，系统会异常关机；

最后尝试在虚拟机里面关掉所有的PCI之后系统重启安装则OK，

但是尝试重新挂载PCI则虚拟机无法启动

#最后，卸载虚拟机、直接在裸机上安装ubuntu机器；

使用npu-smi info查看NPU的情况

 

总结：

tar xvf A300.tar
tar xvf install_gcc&make.tar
sudo dpkg -i *.deb
./A300-3010-npu-driver_20.2.0_ubuntu18.04-x86_64.run --install-username=ubuntu --install-usergroup=ubuntu --full

注意：

ubuntu安装需要在安装系统的过程中安装ssh、因为系统默认不安装、如果跳过后期安装需要直接在服务器上处理，无法远程连接和操作。

finalshell也是一个优秀的远程连接工具；

通过Esxi的ip地址可以直接进入vmware的管理界面，vmware workstation也是通过Esxi访问到服务器的虚拟化服务的；
