操作系统：Linux Mint 20.3
每当我执行 sudo apt update 时，我通常会收到此错误。
dpkg: warning: files list file for package 'libecryptfs1' missing; assuming package has no files currently installed
但它从未引起任何问题。
现在我正在将 Linux mint 升级到 21，升级因抛出以下错误而停止。
dpkg: warning: files list file for package 'libecryptfs1' missing; assuming package has no files currently installed

当我尝试重新安装它时，发生以下错误

不确定该输出意味着什么
注意：我apt update在开始升级之前做了任何有关修复此问题的帮助。
根据 @ab 的建议，我运行了所有命令
粘贴下面最后一个命令的输出

现在，我该如何恢复升级？通过 Mintupgrade 工具还是有任何命令？
答案1
免责声明：我假设系统过去曾发生过文件系统损坏。如果这仅限于一个包的元数据，那很好。如果其他损坏仍然存在或仍在发生（例如：硬件问题），情况可能会更糟。所以重要的数据应该先备份。
目标是重新安装此软件包，同时忽略其以前的元数据部分，这使得它可以卸载。有问题的文件将被移走。通常这个触发文件只是触发运行ldconfig：这是安装提供共享对象库的库包后必须要做的事情。因为我不信任当前的 .deb 文件，所以/var/cache/apt/archives首先清空整个缓存，以便重新下载并重新验证它。触发器文件应替换为升级后的新版本。
首先验证文件系统是否已满或接近满 ( df -h)，并在需要时腾出空间。
以下所有命令必须以 root 身份运行（sudo如果需要，请使用）。
mv /var/lib/dpkg/info/libecryptfs1.triggers /root/libecryptfs1.triggers.badfile
apt clean
apt update
apt-get -f reinstall libecryptfs1
然后就可以像往常一样取出包裹了。如果加密依赖于它，则不应将其删除。
