似乎已libp11-kit.so损坏，我可以通过重新安装来解决问题libp11-kit-dev。但由于apt update不再起作用，我不知道如何实现这一点。或者也许还有其他解决方案或建议？

我刚刚意识到错误是由于 libffi 损坏造成的，我尝试通过http://ubuntu.pkgs.org/20.04/ubuntu-main-amd64/libffi7_3.3-4_amd64.deb.html 下载deb 文件：/ /archive.ubuntu.com/ubuntu/pool/main/libf/libffi/libffi7_3.3-4_amd64.deb并安装它并且dpkg -i它可以工作！
