As explained here, hash sum mismatch errors are usually more typical for clients behind proxy caches. To solve the issue, remove all the content of
Type in the terminal:
sudo rm -rf /var/lib/apt/lists/*
sudo apt update && sudo apt upgrade
It should solve the issue. Ask your Internet Service Provider do they use some proxy. If yes. Then ask can they disable proxy for you.
