我们好，Arch Linux用户！ 每当我尝试从终端使用“ sudo pacman -Syyu”命令升级Arch Linux桌面时，都会收到以下错误消息。

 there is nothing to do

我已经面对此错误已有几天了。
在Arch Linux论坛上搜索后，我找到了该解决方案。
我们最近是否遇到过此错误？
解决此问题的快速而肮脏的解决方法是，我们需要运行以下命令：

$sudo pacman -Syu

上面的命令将主要解决问题并更新所有软件包。

如果没有，请运行此命令。

$sudo pacman -Suu

上面的命令将更新所有软件包，然后降级所有受影响的软件包。

然后，使用以下命令进行完整升级：

$sudo pacman -Syyu
