我通过在 sources.list 中添加条目并评论一些不需要的来源解决了这个问题

sudo add-apt-repository "deb https://apt.dockerproject.org/repo/ $(cat /etc/issue | awk '{print $1}' | tr '[:upper:]' '[:lower:]')-$(lsb_release -cs) main"

之后，它要求我添加缺失的 PUB_KEY

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys F76221572C52609D

在这之后，我

sudo apt-get update

问题解决了
