我设法控制了我的系统，现在更新运行 pacman 进行更新。当尝试更新系统时，系统会报告is corrupted (invalid or corrupted package (PGP signature)
现在似乎缺少 gnupg 程序。尝试执行时gpg会报告以下消息
gpg: symbol lookup error: gpg: undefined symbol: gpgrt_access, version GPG_ERROR_1.0
当我尝试使用sudo pacman -S gnupg以下内容安装 gnupg 时，报告
[Arch ~]$ sudo pacman -S gnupg

我将 /etc/pacman.conf 中的 SigLevel 更改为TrustAll，但仍然看到相同的问题。如何正确安装 gnupg 并解决错误corrupted package (PGP signature)？
谢谢

最后通过Arch BBS 发帖
按照以下步骤操作
我禁用了文件 /etc/pacman.conf 中的检查并恢复了系统，我将 SigLevel 更改为 Never
然后执行：pacman -Scc pacman -Syu
然后重新安装 gpg 包，重新启动系统...并执行：sudo pacman-key --init && sudo pacman-key --populate archlinux && sudo pacman-key --refresh-keys
然后我启用检查密钥并重新启动系统。
按照这些步骤后，我能够安装所有更新并登录到桌面环境。
