Calibre and dedrm problems

Hi guys,

I’m a Linux newbie and recently switched from Windows 10 to Linux Mint Cinnamon 21.3. A lot of things are easy to understand, understandable and work perfectly.

But I can’t solve one problem and am hoping for detailed instructions, including at the command level.

I want to install Calibre and dedrm/nodrm and get them running. I’ve tried all sorts of tips from the internet, but the epub and pdf files keep their drm.

For example, reddit says you need wine winetricks samba and lib32-gnutls. If you follow this advice, lib32-gnutls is already included when you install wine etc. Or wine is 64-bit, but you need 32-bit.

Sure, the information on reddit is older, but no matter what, I can’t get it to work.

Who can help me?
Please give me everything that is necessary at the command level etc.

Hi,

Your message is a little bit confusing and not sure what the actual problem is:

  • You are unable to install dedrm plugin
  • or you have installed it but id does not work as expect.

I assume the first. Here is a short guide how to install DeDRM on Ubuntu/Debian/Mint Linux. I have tested the installation on Debian and there were no problems:

  1. Download the DeDRM plugin. Navigate to DeDRM plugin github page and download a tools zip file: (e.g., DeDRM_tools_7.x.x.zip)
  2. Before you can install it you first must unzip the file.
  3. Locate the: DeDRM_plugin.zip
  4. Open Calibre. Click on Preferences (found at the top bar).
  5. Under the Advanced section, click Plugins.
  6. At the bottom of the plugins window, click Load plugin from file.
  7. Navigate to the downloaded .zip file and select it. not the tools zip but the DeDRM_plugin.zip
  8. Confirm any warnings you may see.
  9. After it is installed, restart Calibre to activate the plugin.

Once installed you should see something like:

Hope this helps. Let me know if you need more help.
