当我跑步时apt-get update我得到

我不知道这是怎么发生的，也不知道如何修复。我安装了 gnupg、gnupg-agent、gnupg-pkcs11-scd、gnupg2、gnupg-curl、gnupg-pkcs11-scd-dbg。

答案1

清除 APT 缓存并重新生成：

sudo apt-get clean
sudo mv /var/lib/apt/lists /tmp
sudo mkdir -p /var/lib/apt/lists/partial
sudo apt-get clean
sudo apt-get update

答案2

做了一个docker system prune(?!) 就解决了。是不是图片状态不好？是不是磁盘空间不足导致的问题？

如果您在 docker 内部遇到问题，也许需要考虑一些事情。

答案3

目录中可能存在无效的链接或文件/etc/apt/trusted.gpg.d/

检查目录是否包含有效的文件和链接，例如：

# ls -L /etc/apt/trusted.gpg.d/* > /dev/null
ls: cannot access '/etc/apt/trusted.gpg.d/live-net-archive-keyring.gpg': No such file or directory

因此，寻找必须包含该文件的包

# dpkg -S /etc/apt/trusted.gpg.d/live-net-archive-keyring.gpg
live-net-archive-keyring: /etc/apt/trusted.gpg.d/live-net-archive-keyring.gpg

并采取以下一些行动：

重新安装它

# aptitude reinstall live-net-archive-keyring

或者重新安装所有已安装的密钥环

# aptitude reinstall $(dpkg -l '*keyring' | awk '$1 == "ii" {print $2}')
The following packages will be REINSTALLED:
debian-archive-keyring gnome-keyring live-net-archive-keyring siduction-archive-keyring

或删除无效的链接或文件

# rm /etc/apt/trusted.gpg.d/live-net-archive-keyring.gpg

答案4

尝试 chown root:root /tmp chmod 1777 /tmp
