由于NO_PUBKEY未找到错误，无法在Ubuntu 18.04.5 LTS上安装NodeJS 14或16

Question

我的目标是安装NodeJS。这是我正在运行的命令:

curl -fsSL https://deb.nodesource.com/setup_16.x | sudo -E bash -

由于以下错误而失败:

W: GPG error: https://releases.parity.io/deb release InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 3B1FE9FFD0787F8B

全栈跟踪在附录a中可用。

我试图解决这个关键问题，并运行以下命令:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 3B1FE9FFD0787F8B

结果是由于缺少密钥而未检查一些签名，完整的堆栈跟踪可作为附录b。

然后，当我尝试使用命令sudo apt-get update更新系统时，我得到错误:The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 3B1FE9FFD0787F8B。完整的堆栈跟踪可在附录c中获得。

如何解决gpg密钥错误，以便安装NodeJS14或更高版本?

更新1:将-k添加到curl:

root@vultr:~# curl -k -fsSL https://deb.nodesource.com/setup_16.x | sudo -E bash -

它没有改变任何东西:

Answer 1

显然释放。parity。Io/deb是未签名的。这个答案建议您可以将[trusted=yes]添加到/etc/apt/sources.list，以避免遇到此错误。

我不知道这有多安全。

编辑:

搜索以

开头的行

deb https://releases.parity.io/deb

并将其更改为

deb [trusted=yes] https://releases.parity.io/deb

链接答案中提到的其他选项也值得一试。

更新1:在正确的文件

中添加[trusted=yes]

文件/etc/apt/sources.list.d/parity.list有这样一行:deb [signed-by=/usr/share/keyrings/parity.gpg] https://releases.parity.io/deb release main。应该修改这一行以使其工作:deb [trusted=yes,signed-by=/usr/share/keyrings/parity.gpg] https://releases.parity.io/deb release main

Answer 2

可能/usr/share/keyrings/的GPG密匙环已经损坏-这就是为什么没有密钥匹配了。您可以创建一个新的密匙环，并开始用apt-key --keyring添加密钥。

也许可以尝试通过端口:80请求(不知道为什么会这样):

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3B1FE9FFD0787F8B
