我在 Hyper-V 中运行 Ubuntu 虚拟机。启动过程中出现无法启动网络的错误。
osis@projmngsys:~$ sudo systemctl status networking

[2]+ Stopped sudo systemctl status networking
里面 sudo nano /etc/network/interfaces 有：
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.1.69
#netmask 255.255.0.0
#gateway 192.168.1.254
#dns-nameservers 8.8.8.8 8.8.4.4 192.168.1.254
#dns-search google.com
在这方面，问题是如何逐步配置Ubuntu和Hyper-V，以便Internet和SSH在其中工作。

我同时遇到了几个问题。Docker 删除后留下垃圾，我执行了命令：
apt remove --purge ubuntu-fan
sudo apt autoremove
接下来，我清理了 Samba 共享文件并删除了挂载设置
sudo nano /etc/fstab
正确地将主机名写入文件
hostname
我将结果名称添加到文件中
sudo nano /etc/hosts
我在文件开头添加了主机信息：
127.0.0.1 MYHOSTNAME
在文件中，我将所有内容恢复为标准设置
sudo nano /etc/network/interfaces
我意识到你需要仔细阅读错误文本并持续解决这些错误。为此，我阅读了
sudo journalctl -xe
sudo systemctl status networking
仔细阅读错误文本，其中有很多信息，感谢大家的帮助。
