安装插件
Calibre本身没有移除DRM的能力，需要借助第三方插件来实现：
下载 DeDRM_tools
wget https://github.com/apprenticeharper/DeDRM_tools/releases/download/v6.6.1/DeDRM_tools_6.6.1.zip
解压zip包
unzip -d DeDRM DeDRM_tools_6.6.1.zip
启动 Calibre
calibre
选择
偏好选项->插件->从文件加载插件
选择
DeDRM_calibre_plugin中的DeDRM_plugin.zip
- 重启 Calibre
移除DRM
安装插件后，在添加书籍的时候，Calibre会自动去掉DRM。而且无法手工对已经添加的书籍移除DRM。
如果要移除已经添加书籍的DRM，则需要先把书籍删掉后，在重新添加。
