我正在开发一个嵌入式系统,使用Debian 8(需要升级)。当我执行apt update
命令时,会收到以下提示:
...

W: GPG error: http://deb.debian.org stable InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 648ACFD622F3D138 NO_PUBKEY 0E98404D386FA1D9 NO_PUBKEY 605C66F00D6C9793
我尝试过:
apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys
但是得到了:

我也尝试过:

返回了以下结果:

我在运行 # apt update
命令后仍然收到了 NO_PUBKEY
错误。这个问题应该如何解决?我的源如下:
cat /etc/apt/sources.list.d/multistrap-debian.list
deb [arch=arm64] http://deb.debian.org/debian stable main contrib non-free
deb-src http://deb.debian.org/debian stable main contrib non-free

现已被弃用。请您为未来的读者添加正确处理方式。谢谢。 - 4wk_sudo
- FlorentE: gnupg、gnupg2和gnupg1似乎未安装,但其中一个是此操作所需的。命令'/bin/sh -c apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 871920D1991BC93C'返回了非零代码:255
。 在我的情况下,我不得不使用Ubuntu 20.04镜像或更新的Debian版本。 - undefined
