Circleci sudo apt key adv间歇性故障

我下面介绍如何在CircleCI上安装Thread，但CircleCI在尝试检查密钥服务器时显示了以下错误：

sudo apt-key adv --keyserver pgp.mit.edu --recv D101F7899D41F3C3
Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret-keyring /tmp/tmp.j5q2IRFiKK --trustdb-name /etc/apt/trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyring /etc/apt/trusted.gpg.d//apt.postgresql.org.gpg --keyserver pgp.mit.edu --recv D101F7899D41F3C3
gpg: requesting key 9D41F3C3 from hkp server pgp.mit.edu
gpgkeys: key D101F7899D41F3C3 not found on keyserver
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0

sudo apt-key adv --keyserver pgp.mit.edu --recv D101F7899D41F3C3 returned exit code 2

Action failed: sudo apt-key adv --keyserver pgp.mit.edu --recv D101F7899D41F3C3

---

错误消息表示GPG无法加载用于验证包签名的公共GPG密钥。尝试这样做：

sudo apt-key adv --fetch-keys http://dl.yarnpkg.com/debian/pubkey.gpg

问题是，

pgp.mit.edu

keyserver有时会中断，这会导致您看到的错误消息。通过URL加载GPG密钥应该更可靠
