在 Linux 上下载和安装 flatpack 的正确方法是什么？
解决方法
先运行 sudo pacman -Syy 解决
请注意，不建议在 -Sy 或 -Syy 之后安装单个软件包。如果您需要使用 -y 更新镜像以安装软件包，您应该将其与完整系统升级 -u 结合使用：
sudo pacman -Syu flatpak
您可能不会看到 -Sy <package> 立即损坏，但最终会随着继续使用而损坏。如果 <package> 碰巧引入了新的 lib 版本，则任何依赖于这些 lib 的程序都 will break since they will still be built against the old libs。
