I get an error message when trying to install an extension of ANY type in any of the Libre Office Products.
It tries to open it in a text editor? I get the following error message … calibre, version 3.21.0
ERROR: Unsupported format: Tweaking is only supported for books in the AZW3 and EPUB formats. Convert your book to one of these formats first."
How do I fix this so it doesn’t try to open in calibre and I can install extensions?
I am using POP OS with KDE on top, with Libre Office 6.0.7.3.
Thanks.
