鉴于官方已不再支持deepin23.1了，而deepin25.1.0又有linglong和磐石，本人改造它已经很久了，所以最近本人就修复了它最后几个小问题，并深度自定义了内核、版本、修复了所有漏洞…

音频不同步、无线网时序问题、福昕pdf阅读编辑、安装搜狗输入法官方个人版(因为它比搜狗next好用很多)等，具体修复如下(经本人验证可行):

1. 软件源修复（核心）

更换为中科大源

sudo tee /etc/apt/sources.list << 'EOF'
deb https://mirrors.ustc.edu.cn/deepin/beige/ beige main commercial community
deb https://com-store-packages.uniontech.com/appstorev23 beige appstore
EOF

更新源

sudo apt update

2. 音频修复（PipeWire）

systemctl --user daemon-reload
systemctl --user unmask pipewire.socket pipewire-pulse.socket
systemctl --user unmask pipewire.service pipewire-pulse.service
systemctl --user enable pipewire.socket pipewire-pulse.socket
systemctl --user enable pipewire.service pipewire-pulse.service
systemctl --user start pipewire.socket pipewire-pulse.socket
systemctl --user start pipewire.service pipewire-pulse.service

3.配置开机网络等待5秒

创建 override 配置文件

sudo mkdir -p /etc/systemd/system/systemd-networkd-wait-online.service.d/
sudo tee /etc/systemd/system/systemd-networkd-wait-online.service.d/override.conf << 'EOF'
[Service]
ExecStart=
ExecStart=/usr/lib/systemd/systemd-networkd-wait-online --timeout=5
EOF

重载配置

sudo systemctl daemon-reload

重启测试

sudo reboot

重启后验证

systemd-analyze blame | grep networkd-wait-online

4. Foxit Reader 修复

sudo tee /opt/foxitsoftware/foxitreader/FoxitReader-deepin.sh << 'EOF'
#!/bin/bash
unset LD_LIBRARY_PATH
export QT_QPA_PLATFORM=xcb
/opt/foxitsoftware/foxitreader/FoxitReader "$@"
EOF
sudo chmod +x /opt/foxitsoftware/foxitreader/FoxitReader-deepin.sh

sudo tee /usr/share/applications/FoxitReader.desktop << 'EOF'
[Desktop Entry]
Name=Foxit Reader
Comment=View pdf documents
Type=Application
Exec=/opt/foxitsoftware/foxitreader/FoxitReader-deepin.sh %F
Icon=FoxitReader
Categories=Office;Viewer;
MimeType=application/pdf;
EOF
sudo update-desktop-database

5.卸载搜狗 Next (fcitx5 版本) 及其所有相关组件

卸载主包和相关组件

sudo apt purge com.sogou.ime.ng.fcitx5.deepin sogou-ime-ng sogou-ime-ng-cpis-*

清理依赖和配置文件

sudo apt autoremove --purge

手动删除残留配置

rm -rf ~/.config/SogouPY* ~/.config/sogou* ~/.local/share/fcitx5 ~/.config/fcitx5

验证是否清理干净

dpkg -l | grep -i sogou

6. 安装fcitx4 输入法框架及其组件

sudo apt install fcitx fcitx-config-gtk fcitx-frontend-gtk3 fcitx-frontend-qt5 fcitx-googlepinyin

安装sogoupinyin_4.2.1.145_amd64.deb

cd ~/Downloads
sudo dpkg -i sogoupinyin_4.2.1.145_amd64.deb

搜狗拼音锁定

sudo chattr +i /opt/sogoupinyin/files/bin/sogoupinyin-service
sudo chattr +i /opt/sogoupinyin/files/bin/sogoupinyin-watchdog
sudo chattr +i /usr/bin/fcitx
sudo chattr +i /usr/lib/x86_64-linux-gnu/fcitx/fcitx-sogoupinyin.so
