当我最终决定升级运行 vanilla Arch Linux 的笔记本电脑时(由于互联网问题)，我不断收到如下错误:

$ sudo pacman -Syu

由于互联网问题，我已经有近一个月或更长时间没有更新/升级了。我尝试了人们在其他网站上建议做的所有事情，包括堆栈溢出，但没有一个起作用。

我尝试过:

$ sudo pacman -Rdd catalyst                             47.6s  Fri 21:44
error: GPGME error: No data
error: GPGME error: No data
error: target not found: catalyst

$ sudo pacman -Syu                                              Fri 21:44
error: GPGME error: No data
error: GPGME error: No data
**and the same thing as "$ sudo pacman -Syu"**

This is also the same output for $ sudo pacman -Syy

我也尝试过

$ sudo pacman -Scc
$ sudo pacman-key --init
$ sudo pacman-key --populate archlinux                     1394ms  Fri

但是没有任何效果，根本没有改变。
有谁知道为什么会发生这种情况？是不是因为我太久没有更新Arch Linux了？我该如何解决这个问题？

谢谢!

删除然后更新

在终端

2. $ sudo pacman -Syu
