怎么办呢，论坛上传不了图片。
正常模式进入不了了，选择systemd模式能进入桌面，但是无网络，无线和有线都不行，能采用什么方法修复呢？

1. Ubuntu 15.04 / 15.10 預設就是 systemd 初始化
你說的 正常模式 就是 systemd 初始化

2. 但是你的開機選單 跟一般不同
2-1. 登入桌面
把下面指令 複製 貼進終端機 執行
2-1-1. sudo update-initramfs -u -k all
2-1-2. sudo update-grub
意思就是 重新產生最新的開機選單
然後
2-1-3. sudo reboot
看看
2-2. 上述指令 隨時可以執行 以產生最新的開機選單

3. 如果你想更換為 upstart
請參考
https://wiki.ubuntu.com/SystemdForUpsta ... it_systems
3-1. Switch to upstart for a single boot
3-2. Permanent switch back to upstart

4. 把下面指令 複製 貼進終端機 執行
4-0. uname -r
4-1. sudo lspci -knn
4-1-1. 如果無線網卡是 usb 裝置 請增加
sudo lsusb
4-2. sudo lshw -numeric -class network
4-3. sudo ifconfig -a
4-4. sudo route -nv
4-5. sudo rfkill list all
4-6. sudo nmcli dev status
4-7. sudo dhclient -v
4-8. sudo iwlist scan
把你的 ESSID 那一段落 直接 選取/複製 貼上來
4-9. sudo ls -al /etc/resolv.conf
4-10. sudo cat /run/resolvconf/resolv.conf
4-11. sudo dkms status
4-12. sudo cat /etc/NetworkManager/NetworkManager.conf
4-13. sudo cat /etc/network/interfaces
把結果直接 選取/複製 貼上來
把結果直接複製 貼到
http://paste.ubuntu.com
再把回應網址
http://paste.ubuntu.com/xxxxxxx
貼上來

感 谢大大的回复，花了一天一夜重装系统报告修复过程。

我尝试先修复网络，提示网络管理没了

再进行重新產生最新的開機選單，也没任何反应。

由于无网络，出错代码代码无法贴出来。决定还是重装。这次升级失败是从lubuntu15.04升级的，好几年没有重装了，系统从以前一路升级过来的，里面就有三个桌面，一个GONME，一个那个坑爹吃大资源的，一个就是LUBUNTU，这几年一直都用LUBUNTU.

所以下载了LUBUNTU 15.10 ISO做了U盘启动，这次留了个心眼，先尝试运行不安装，长时间结果停在了第一个进度小圆点上面，重启也不行，只能关机。

重新下载了15。04。 ISO做了U盘启动，因为之前15。04是能够正常使用的，所以直接进行安装。最后提示安装成功重启，就出现下面截图的错误。重启不了，只能关机，怀着捉狂的心情重新开机，居然没提示错误正常进入系统。


现在也没出现任何错误。15。10应该是无福享受，纪念一下老机以后升级先用U盘启动尝试能不能正常运行再进行安装

感谢大大，感谢UBUNTU，感谢LUBUNTU，老机焕发青春

如果 15.04 能夠使用 15.10 不行
最大可能是 顯卡驅動不支援 15.10 的 kernel 版本
或者 顯卡硬件 不支援 3D
這只是猜測

1. 如果你想確認看看 上面猜測是否準確
把下面指令 複製 貼進終端機 執行
1-1. uname -r
1-2. sudo lspci -knn
1-3. sudo lshw -numeric -class video
1-4. sudo ubuntu-drivers devices

本本是显卡是GF 9300M GS，目前能够安装上NVIDIA-Linux-x86_64-340.96.run 驱动。
