kubuntu 18.04 默认主题 Breeze-Dark Plasma主题修复日记
KDE Plasma 5.12 LTS
原因是下午5点半,更改锁屏图片,后来想想硬盘空间不大,删除了纯色背景
在设置图片就发现有问题了,有的项不显示了,心里想不会搞坏了吧,结果一锁屏,黑屏了
当时不知道可以切 命令行,强制重启了,
还好固态没有崩溃
但是主题崩了,
Kubuntu shows error at login (file:///usr/share/sddm//themes/breeze/Main.qml:No such file or directory)
进系统时按 shift 或是 esc 进修复模式,结果没有用
找了很多资料,很多方案,都行不通,最后找到这个国外文章,觉得是一模一样的问题,
How to Install the KDE Plasma Desktop on Ubuntu 18.04 LTS
链接
也不行,(这里应该可以)
最后晚上11点找到这个文章,通过自己的思考,悟出来了:
Had the exact same issue after uninstalling some basic programs through the UI. Fixed it with apt-get install sddm-theme-breeze apt-get install --reinstall plasma-desktop The first install made it possible to log on again and the second one fixed the rest. You may use a virtual terminal to login (by pressing ctrl+alt+F1; if that doesn't work, try the other virtual terminals from ctrl+alt+F2 up to ctrl+alt+F6).
但是怎么执行都报这个错误
Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
最后想想是不是命令行没有网络,
ping 163.com
果真是不通的,找跟有线网线,接上,再ping 就可以了
按照上面
apt-get install sddm-theme-breeze apt-get install --reinstall plasma-desktop
办好了,真是方法很简单,命令很简单,但是你不知道就不知道多难,记录,希望帮到你
