The error information indicates that your Calibre is using an external Python library, which may have caused many problems. I suggest you follow the installation instructions provided by Calibre to install a version of Calibre that contains a built-in Python. This may help resolve the issue.

[nemelu]

I installed Calibre from the system package manager. I don't want to installed it manually.

The problem is that Python 3.12 deprecated the key_file parameter in http.client.HTTPSConnection but the package mechanize that your plugin depends on is still using it.

So, I guess I will have to wait until they fix that.

[bookfere]

Your Calibre is not a self-contained version, so the plugin just depends on the mechanize package you installed.

From the the issue of mechanize, this is a bug that exists in versions lower than v0.4.10. Fortunately, the issue has been addressed in version v0.4.10. Therefore, you need to upgrade mechanize to the latest version to resolve the issue.

Thank you for the clarification. Sorry for wasting your time. Now I just need to wait for the package update.
