dpkg退出并错误解析文件`/ var / lib / dpkg / status`，该怎么办？

尝试安装任何软件时，都会遇到此错误，因此无法更新。

Preconfiguring packages ...
dpkg: error: parsing file '/var/lib/dpkg/status' near line 51245 package 'oracle-xe':
 mixed non-coinstallable and coinstallable package instances present
N: Ignoring file 'gcl' in directory '/etc/apt/sources.list.d/' as it has no filename extension
N: Ignoring file 'gcl' in directory '/etc/apt/sources.list.d/' as it has no filename extension
E: Sub-process /usr/bin/dpkg returned an error code (2)

幸运的你！您有备份！甚至，它们每天都在您不知情的情况下制成！因此，要恢复文件，只需运行：

sudo rm /var/lib/dpkg/status
sudo cp /var/backups/dpkg.status.0 /var/lib/dpkg/status
sudo apt-get update

做完了！

如果您需要更旧的文件，则还有更多选择：

ls /var/backups/dpkg.status*
/var/backups/dpkg.status.0     /var/backups/dpkg.status.4.gz
/var/backups/dpkg.status.1.gz  /var/backups/dpkg.status.5.gz
/var/backups/dpkg.status.2.gz  /var/backups/dpkg.status.6.gz
/var/backups/dpkg.status.3.gz

只需使用gunzip以下命令解压缩它们：

gunzip -c /var/backups/dpkg.status.6.gz > /var/lib/dpkg/status

如果备份不好，则另一种方法是列出doc目录内容：

sudo -i
ls /usr/share/doc | \
      grep -v [A-Z] | \
      grep -v '^texmf$' | \
      grep -v '^debian$' | \
      awk '{print $1 " install"}' | \
      dpkg --set-selections
