linux - Ubuntu升级14.04出错

Question

事情的经过比较长
昨晚换了一个yun-idc的源更新，提示可以升级系统到14.04，手贱点了。
过了一夜，今早发现升级窗口的terminal中经常出现：

Fontconfig error: "/etc/fonts/conf.d/65-khmer.conf", line 14: out of memory
Fontconfig error: "/etc/fonts/conf.d/65-khmer.conf", line 23: out of memory
Fontconfig error: "/etc/fonts/conf.d/65-khmer.conf", line 32: out of memory

终于最后一次出现这个bug，系统假死，全无响应，硬盘灯长亮。再次手贱强制关机重启。
然后就进不去图形界面了。



尝试回车之后就进入了只有一个提示符的屏幕，没有然后了。

可以Ctrl+Alt+F1登陆，但是不能用Wi-Fi联网。
以上

请问各位有什么解决的思路么？小弟的毕设还在系统里丢不得……
先谢过帮忙的各位了！

很多朋友建议重装，再次谢谢各位了！
但是小弟不死心，想试一试在CtrlAltF1下尝试联网，修改源，再等Ubuntu正式发布14.04的时候do-release-update，各位大大觉得有希望么？
谢谢！

Answer 1

Okay, I solved this problem myself.

The idea is to enter CtrlAltF1 and plug in the Internet cable. Fortunately, there is a network, so apt-get update && apt-get upgrade
When upgrading, you are prompted to -f install some packages, so do so
So began the long setting up......
After the end, I upgraded again, and then started the long setting up...
I don’t know what else to do after it’s over, so restart.

That’s it, the system has been updated to 14.04LTS.

This kind of repair is probably done by chance. Thanks again to all those who helped!

Answer 2

Ubuntu upgrade is not done well, problems often occur, and the upgrade effect is not as good as reinstalling. You can connect to the Internet via wired network first, and then copy the data out

Answer 3

I encountered this situation when installing Ubuntu on VBox. From the prompts, it seems that the graphics device such as the graphics card does not have a driver. I don’t know the specific solution. But you can back up the data first and then consider reinstalling.

If you made a /home partition when partitioning, the partition will not be included in the reinstallation, and the data will be there.

Answer 4

I have never been successful in upgrading Ubuntu. Try arch or gentoo. You can copy files from livecd

Answer 5

If the data is not in the disk where the root directory is, just reinstall it directly. For a safe point, you can use a USB flash drive to make a simple system like puppy first, copy the data out and then reinstall it
