The solution is to correctly configure the software installation source. For details, please refer to this article, which details how to correctly configure the system software source.

Method 2

Try to repair system dependency corruption, delete apt cache and list directory files, and then rebuild the package index.

apt-get clean
rm -rf /var/lib/apt/lists/*
apt-get update
