(flatpak 添加源、修改国内镜像) flatpak report: error: The application com.tencent.WeChat/x86_64/master requires the runtime org.freedesktop.Platform/x86_64/23.08 which was not found

[ysl2]

Ref: https://mirror.sjtu.edu.cn/docs/flathub

官方添加源的方式：

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

如果之前没有添加过官方的源，就直接添加国内镜像：

sudo flatpak remote-add flathub https://mirror.sjtu.edu.cn/flathub/flathub.flatpakrepo

否则，如果之前添加过官方的源，就将其修改为国内镜像：

sudo flatpak remote-modify flathub --url=https://mirror.sjtu.edu.cn/flathub

# 如果上述出现错误，可尝试：
wget https://mirror.sjtu.edu.cn/flathub/flathub.gpg
sudo flatpak remote-modify --gpg-import=flathub.gpg flathub

如果某次安装被中断，则需要修复：

flatpak repair
