无法安装任何软件包：“软件包 linux-image-5.4.0-42-generic 缺少最后的换行符”？

我尝试在 Ubuntu 20.04.5 上安装一些软件包更新，但一切都失败了：

dpkg: unrecoverable fatal error, aborting:
 files list file for package 'linux-image-5.4.0-42-generic' is missing final newline

我该如何解决这个问题？

这是我尝试过的示例：

您的/var/lib/dpkg/info/linux-image-5.4.0-42-generic.list文件已损坏。您应该将其移开，然后dpkg才能继续：

sudo mv /var/lib/dpkg/info/linux-image-5.4.0-42-generic.list{,.bak}

理想情况下，您可以重新安装该软件包，以便dpkg可以正确删除它，但这可能不再可能（该软件包无法从存储库中获得）。您应该手动检查其中列出的内容/var/lib/dpkg/info/linux-image-5.4.0-42-generic.list.bak并删除其中列出的不属于任何其他包的任何文件（用于dpkg -S检查）。

您可能需要手动清理/lib/modules/5.4.0-42-generic；/boot也检查并删除相应的vmlinuz文件（initrd如果有）。
