dpkg: error: parsing file '/var/lib/dpkg/status' near line 0

系统会自动备份该文件

解决方案：
sudo rm /var/lib/dpkg/status
sudo cp /var/backups/dpkg.status.0 /var/lib/dpkg/status
sudo apt-get update

如果还不行使用更旧的文件即可

ls /var/backups/dpkg.status*

sudo cp /var/backups/dpkg.status.1 /var/lib/dpkg/status
sudo apt-get update
