我想通过以下方式升级我的 Arch Linux 发行版系统：
yay -Syu
但不幸的是，当我尝试导入新的 GPG 密钥时，出现了 DNS 错误

但是，我能够从 dig 中获得正确的 DNS 响应：
dig hkps.pool.sks-keyservers.net
; <<>> DiG 9.16.8 <<>> hkps.pool.sks-keyservers.net

我忽略了什么？
答案1
最后我找到了一个解决方案，
spotify 软件包存在问题，可以通过 spotify 软件包讨论中的置顶评论解决 -https://aur.archlinux.org/packages/spotify/#pinned-747857
所以我跑了
curl -sS https://download.spotify.com/debian/pubkey_0D811D58.gpg | gpg --import -
现在一切都正常了！
