替换源

运行

sudo gedit /etc/apt/sources.list

将源文件全部删除，替换成如下：

#阿里源deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

更新

sudo apt-get update sudo apt-get upgrade

安装

sudo apt install fcitx fcitx-ui-qimpanel sudo apt install fcitx-pinyin

为fcitx设置自启动

避免重启后输入系统消失

键盘输入法切换为fcitx

切换后为安装搜狗输入法做准备

总结

以上是生活随笔为你收集整理的Ubuntu1804键盘输入系统无fcitx的解决方法的全部内容，希望文章能够帮你解决所遇到的问题。
