完成！刚刚解决问题。
原来，libcrypto.so.1.0.0失踪了。
我开始用以下方法搜索：
xyz@xyz-laptop:~$ sudo locate libcrypto.so.1.0.0
/snap/core/11420/lib/x86_64-linux-gnu/libcrypto.so.1.0.0
然后在对其进行罚款后，我开始复制它：
xyz@xyz-laptop:~$ sudo cp /snap/core/11420/lib/x86_64-linux-gnu/libcrypto.so.1.0.0 /usr/lib/
就是这样！
我现在可以使用 进行升级sudo apt upgrade。
