解决网络连接缺失问题

  • 772

将我的家用服务器计算机上的操作系统从 Debian 11 升级到 Debian 12（通过更改 sources.list 并使用 apt 命令）然后重新启动计算机后，我没有网络连接，也没有 IP 地址。我该如何解决问题？这台电脑是 SolidRun Cubox i2eX，使用 Freescale 芯片 i.MX6 Dual。我使用的是有线连接，如果我将其插入另一台电脑，它就可以正常工作（更新期间工作正常）。有什么线索吗？

    就我而言，问题在于文件中的主网络接口设置为 eth0 /etc/network/interfaces。将 eth0 替换为 end0 并重新启动网络服务即可解决问题。

    cp -n /etc/network/interfaces /etc/network/interfaces.orig
sed -i 's/\beth0\b/end0/g' /etc/network/interfaces
systemctl restart network
