我遇到了同样的问题。我是这样解决的：
sudo sed -i -e 's/archive.ubuntu.com\|security.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list
grep -E 'archive.ubuntu.com|security.ubuntu.com' /etc/apt/sources.list.d/*
sudo apt-get 更新
您需要将存储库目标更新为 Ubuntu 的 Eoan Ermine (19.10) 版本。可以这样做：
sudo sed -i -e 's|disco|eoan|g' /etc/apt/sources.list
