[Archlinux] zig: signature from .... is unknown trust

`pacman -Syu` 的時候遇到了：

 error: zig: signature from "Daurnimator <quae@daurnimator.com>" is unknown trust

:: File /var/cache/pacman/pkg/zig-0.8.0-1-x86_64.pkg.tar.zst is corrupted (invalid or corrupted package (PGP signature)).

Do you want to delete it? [Y/n] y

error: failed to commit transaction (invalid or corrupted package)

Errors occurred, no packages were upgraded. 

更新 keyring (`sudo pacman-key --refresh-keys`)：

gpg: refreshing 125 keys from hkp://p80.pool.sks-keyservers.net                        

gpg: keyserver refresh failed: No name                                                                                                                                        

==> ERROR: A specified local key could not be updated from a keyserver. 

這時更換一下 keyserver：

https://wiki.archlinux.org/title/Pacman/Package_signing#Change_keyserver

換成 ubuntu 的 keyserver: `/etc/pacman.d/gnupg/gpg.conf`

```
keyserver hkp://keyserver.ubuntu.com

```
再清理 cache: sudo pacman -Sc

然後再一次 `sudo pacman-key --refresh-keys`

結果遇到：
==> ERROR: A specified local key could not be updated from a keyserver.

再更新一下 keyring
`sudo pacman -S archlinux-keyring`

再 refresh 一次：`sudo pacman-key --refresh-keys`

結果依舊：
==> ERROR: A specified local key could not be updated from a keyserver.

^ 不要鳥他 我沒有解決

直接 `sudo pacman -Syu` 完成。
