亲测搜狗输入法在 Ubuntu 24.04LTS 以及 Linux Mint 22.1 系统安装好后会出现无法输入中文的情况。
有两种解决办法：
下面介绍方法 2 的修复步骤。
首先退出 Fcitx 程序，然后在终端执行 sogoupinyin-watchdog 程序。
sudo su
/opt/sogoupinyin/files/bin/sogoupinyin-watchdog执行完成之后，查看终端的错误输出，例如我的输出:
./sogoupinyin-watchdog: /opt/sogoupinyin/files/bin/../lib/qt5/lib/libQt5Gui.so.5: no version information available (required by ./sogoupinyin-watchdog)
./sogoupinyin-watchdog: /opt/sogoupinyin/files/bin/../lib/qt5/lib/libQt5Widgets.so.5: no version information available (required by ./sogoupinyin-watchdog)
./sogoupinyin-watchdog: /opt/sogoupinyin/files/bin/../lib/qt5/lib/libQt5Core.so.5: no version information available (required by ./sogoupinyin-watchdog)
./sogoupinyin-watchdog: /opt/sogoupinyin/files/bin/../lib/qt5/lib/libQt5Core.so.5: no version information available (required by ./sogoupinyin-watchdog)
./sogoupinyin-watchdog: /opt/sogoupinyin/files/bin/../lib/qt5/lib/libQt5DBus.so.5: no version information available (required by ./sogoupinyin-watchdog)
./sogoupinyin-watchdog: symbol lookup error: ./sogoupinyin-watchdog: undefined symbol: qt_version_tag, version Qt_5.6这是一些 Qt5 包不存在版本信息；系统中的 Qt 包在路径 /usr/lib/x86_64-linux-gnu 路径下；只需要将这些 Qt 拷贝到搜狗中即可 /opt/sogoupinyin/files/lib/qt5/lib，可以使用下方脚本，软链接系统的 Qt 至 搜狗输入法中的 Qt，记得给脚本添加可执行权限。
