答案1
打开终端并运行：
清除（以前的版本）：
sudo apt -y purge squid* &> /dev/null
sudo rm -rf /var/spool/squid/* /var/log/squid/* /etc/squid3 /dev/shm/* &> /dev/null
安装：
sudo apt -y install squid squid-langpack
if [ ! -d /var/log/squid ]; then sudo mkdir -p /var/log/squid && sudo touch /var/log/squid/{access,cache}.log && sudo chown -R proxy:proxy /var/log/squid; fi
Crontab（可选）：
sudo crontab -l | { cat; echo "@weekly squid -k rotate"; } | sudo crontab -
