解决E: Encountered a section with no Package: header问题

在尝试使用sudo apt-get install watchdog命令在树莓派3b的Linux系统上安装看门狗软件时,遇到了错误:Error! Encountered a section with no Package: header和Problem with MergeList /var/lib/dpkg/status。为了解决这个问题,建议首先备份状态文件,然后从/var/backups目录中选择最新的dpkg.status备份进行复制,替换现有状态文件。之后运行sudo apt-get update和sudo apt-get watchdog检查是否已修复问题。如果仍未解决,可以尝试使用更早的备份文件。

项目场景:

树莓派3b,linux系统,安装看门狗,安装报错。

问题描述:

通过命令

sudo apt-get install watchdog

安装watchdog包报错:

Reading package lists... Error!
E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/dpkg/status
E: The package lists or status file could not be parsed or opened.

解决方案:

首先备份:

mv /var/lib/dpkg/status /var/lib/dpkg/status.old

要是提示没有权限,请加上sudo

您现在需要做的是获取此状态文件的备份并使用它。备份文件存储在/var/backups目录中。您可以列出它:

ls -l /var/backups/dpkg.status*

复制最新的备份:

cp /var/backups/dpkg.status.0 /var/lib/dpkg/status

现在尝试运行更新,看看问题是否已解决

sudo apt-get update
sudo apt-get watchdog

如果没有,您可以尝试使用下一个备份文件。如果文件已存档,则需要先将其解压缩。复制后,再次运行update命令并检查是否已修复。
