无法在Ubuntu上获取sudo更新

Question

我的18.04 Ubuntu服务器有问题。

当我尝试运行"sudo apt-get update“时，我得到了这个(代码1)

当我尝试为乳齿象(joinmastodon.org)启动一些服务时，我也得到了这个错误(代码2)

代码1

● mastodon-streaming.service - mastodon-streaming
   Loaded: loaded (/etc/systemd/system/mastodon-streaming.service; disabled; vendor preset: enabl

代码2.2

我认为这是一个网络问题，但我不知道如何解决它。提前谢谢你。

Answer 1

为纱线运行添加最新的关键点

curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -

Answer 2

代码1中"apt-get update“的问题是，您被误认为是公钥23E7166788B63E1E。您可以通过执行以下命令将此密钥添加到您的密钥环中：

sudo apt-key adv --recv-key 23E7166788B63E1E

它将向您显示类似以下内容：

Executing: /tmp/apt-key-gpghome.6KxIWRrerk/gpg.1.sh --recv-key 23E7166788B63E1E
gpg: key 1646B01B86E50310: public key "Yarn Packaging <yarn@dan.cx>" imported
gpg: Total number processed: 1
gpg:               imported: 1

现在您可以运行"apt-get update“或"apt update"，它也会获取https://dl.yarnpkg.com/debian/dists/stable/InRelease的索引。
