每次安装或删除软件包时，都会出现LVM2错误
我需要帮助来处理这个错误。 我运行Ubuntu Budgie 18.04LTS。
anon@computer:~$ sudo dpkg --configure -a Setting up lvm2 (2.02.176-4.1ubuntu3) ... update-initramfs: deferring update (trigger activated) Failed to restart lvm2-lvmetad.service: Unit lvm2-lvmetad.socket is masked. invoke-rc.d: initscript lvm2-lvmetad, action "restart" failed. ● lvm2-lvmetad.service - LVM2 metadata daemon Loaded: loaded (/lib/systemd/system/lvm2-lvmetad.service; static; vendor preset: enabled) Active: inactive (dead) Docs: man:lvmetad(8) dpkg: error processing package lvm2 (--configure): installed lvm2 package post-installation script subprocess returned error exit status 1 Processing triggers for initramfs-tools (0.130ubuntu3.1) ... update-initramfs: Generating /boot/initrd.img-4.15.0-23-generic Errors were encountered while processing: lvm2 anon@computer:~$ 以上是我在安装/删除软件包时看到的内容。 我对linux很新。 我无法弄清楚如何解决这个问题。 重新安装LVM2软件包没有帮助，也没有dpkg --configure -a或dpkg --configure lvm2 。 但是，我可以很好地安装和删除软件包，似乎包括lvm2本身。
我也尝试过：
anon@computer:~$ sudo service lvm2-lvmetad start Failed to start lvm2-lvmetad.service: Unit lvm2-lvmetad.socket is masked. anon@computer:~$ sudo systemctl enable lvm2-lvmetad.socket Failed to enable unit: Unit file /etc/systemd/system/lvm2-lvmetad.socket is masked.
然后我尝试了这里链接的修复，但也没有用。 在检查了lvmetad联机帮助页后，我做了：
anon@computer:~$ sudo pvscan --cache [sudo] password for anon: WARNING: Failed to connect to lvmetad. Falling back to device scanning. anon@computer:~$
最后我也试过骑自行车的动力，更新和升级一切等等。请不要提出想法。
更新：我尝试直接取消屏蔽套接字。 起初它似乎工作，因为当我启用然后启动lvm2-lvmetad服务它没有说失败。 我尝试升级包，同样的错误仍然存在。

在程序包管理期间仍然出现错误。
编辑：修复。 请参阅我的评论以获取详细信息这是一个损坏的lvm2依赖项。
升级到18.10测试版后我遇到了完全相同的问题。
什么对我有用：
rm -rf / etc / lvm apt purge lvm2 apt install lvm2
