安装或删除任何软件“lvm2-lvmetad.service”的问题

我正在尝试安装或删除任何软件，但遇到以下错误：

Failed to restart lvm2-lvmetad.service: Unit lvm2-lvmetad.socket is masked.

我试图在这里学习一些教程，但对我不起作用。

Answer 1

我已经解决了这个问题：

sudo apt-get purge lvm2
sudo apt autoremove
sudo apt install lvm2

重新启动系统，并安装新内核。此外，这个讨论对我有帮助。

Answer 2

如果systemctl status lvm2-lvmetad返回，Loaded: masked (/dev/null)您应该取消屏蔽并启用它

sudo systemctl unmask  lvm2-lvmetad && sudo systemctl enable lvm2-lvmetad

该命令systemctl status lvm2-lvmetad.socket应返回确认成功的状态。

如果这种方法对您不起作用，那么使用此处描述的清除/重新安装方法可能会更好，但我建议您进行良好的备份。
