答案1
您可能有一个文件包含/etc/apt/sources.list.d无效的存储库定义。删除该错误就不会再出现。
答案2
E: The repository 'https://download.docker.com/linux/debian kali-rolling Release' does not have a Release file.
Docker 没有kali-rolling.您应该使用 debian 代号。
Debian 衍生品（例如“BunsenLabs Linux”）的用户，“卡利Linux”或“LMDE”（基于 Debian 的 Mint）应遵循 Debian 的安装说明，用其发行版的版本替换相应的 Debian 发行版。请参阅您的发行版的文档，查找与您的衍生版本相对应的 Debian 版本
echo "deb [arch=amd64] https://download.docker.com/linux/debian buster stable" | \
sudo tee /etc/apt/sources.list.d/docker-ce.list
正如斯蒂芬所说,删除下面的文件/etc/apt/sources.list.d 这是错误的根本原因。
