Question

我的18.04 Ubuntu服务器出现问题。

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

当我尝试为mastodon（joinmastodon.org）启动某些服务时，我也收到此错误（代码2）

代码2.1

mastodon@dedi-par-72088:~$ systemctl status mastodon-streaming.service
● mastodon-streaming.service - mastodon-streaming
   Loaded: loaded (/etc/systemd/system/mastodon-streaming.service; disabled; vendor preset: enabl

代码2.2

mastodon@dedi-par-72088:~$ systemctl enable mastodon-*
Failed to enable unit: The name org.freedesktop.PolicyKit1 was not provided by any .service files

我认为这是网络问题，但我不知道如何解决。预先谢谢你。

Answer 1

代码1中的“ apt-get更新”问题是您错过了公钥23E7166788B63E1E。您可以通过执行以下操作将此密钥添加到密钥环：

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

它将显示以下内容：

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更新”或“ apt更新”，它还将获取https://dl.yarnpkg.com/debian/dists/stable/InRelease的索引。

Answer 2

为纱线运行添加最新密钥

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

无法在Ubuntu上获取sudo更新
