If this is not the correct cert for you, you can follow these steps (for Firefox on desktop, may vary for other browsers or mobile):
1. Go to https://acs.cdn.overdrive.com (from the "Loading book from ..." log message in Calibre)
2. Click the "lock" icon at the left end of the URL bar, click "Connection secure" then "More information"
3. This page has 3 tabs, for me the middle one was the one I cared about -- "GTS CA 1P5"
4. Go to https://pki.goog/repository/ (linked from the bottom of the middle tab), and scroll down to the "Subordinate CAs" section.
5. Find the cert you need and click "Action" to download the certificate format you need, then install it

Thank you! This worked for me too, problem resolved.

I’m not using this plug-in, but could this certificate issue be what’s causing my sudden inability to properly interact with any of my Overdrive websites, no matter which browser I use?

How do I know which security certificate I need? (I’m on a Mac.) Thanks.

I'm using the OverDrive Libby plugin to download acsm files (I'd hoped it would download epubs, but I only get acsms).

I then installed DeACSM. I'd hoped it would download the epub once the acsm file appeared in Calibre or once I double clicked on the acsm file in Calibre. However nothing happens on import and when I double click my computer launches ADE and that downloads the epub (which I can then import to Calibre). I've installed the certificate referenced in the last few posts.

How can i fix this?

You need to add the original ACSM file to calibre after installing the plugin. After install, it is part of the import pipeline so you would have to remove the .acsm files from calibre and then use Add books to re-add them.

I installed the DeACSM plugin.

I then used the OverDrive plugin to add the ACSM file to Calibre.

I'm not understanding what I should do next.

My present workflow is import an ACSM with the OverDrive plugin, double click on it, wait for ADE to finish fetching the epub, then Add the epub to Calibre. It does not sound as if the DeACSM plugin is any easier.

Am I understanding correctly?

For me, the DeACSM plugin is easier. I download the .ascm file, use the Add Books tool to add it to calibre and during the add pipeline, the epub is downloaded.

I use Firefox to download the .acsm files, for my personal preferences it is easier to download from multiple sites using one tool. If I only obtained ePubs from libraries, the Overdrive plugin might be more useful but I obtain ePubs from multiple sites.

One item to remember is that like the majority of the input plugins, DeACSM only sees the file during the import process. You can't click on the file once it has been imported.

If I recall correctly, the Overdrive Libby plugin will use the DeACSM plugin to obtain the epub version during the import process so if both are installed and configured, you should get an ePub when a .acsm file is downloaded.

My download preference is to drop ACSMs into an unsorted downloads folder. Then I move them to a Calibre autoadd subfolder.

Don't download directly to the autoadd folder. You might end up with files autoadded mid-download.

Alas, the key word is "should". Based on this thread and the Overdrive thread, it should work. Alas, it does not and I can't figure out why not.

Any idea about things to try?

What are your settings for both plugins?

Images attached, as requested. Sorry about that.

Obscure links is technically pushing the rules since you don't know what the image will actually BE

The probable issue is that your library is sending you .acsm files that require your Adobe ID to download the file. Basically, the .acsm file from the library gets send to ADE. ADE then generates a request signed with the key generated when ADE was registered to your Adobe ID. Once you opened the book with your Adobe ID, anonymous or any other Adobe ID will not work. I would suggest using the same Adobe ID for DeACSM as you are using for ADE.

I tried helping a friend to install the ACSM plugin on their computer. I had downloaded the 0.0.16 version from the second message and also the 0.1.0 beta and neither would install. Their computer is running Windows 11. We tried using pip to install oscrypto but that did not work either.

That did it!
