Debian 12 to 13 - KNotes Gone?

I just performed an in-place upgrade from Debian 12 to Debian 13, using KDE Plasma as my desktop. I have used KNotes to keep information handy on my desktop; it seems to work better than the Plasma Sticky Notes widget for my workflow. Upon restarting, I cannot find KNotes, and it does not appear to be available for download through Discover or the web. Is there a way for me to recover KNotes or to import its data into another program? I also have a backup of my home folder using Backups in System Settings; could I recover my notes data from there? Thank you in advance.

It was removed 2 years ago (from the more up to date distros):

Thank you for the reply. I installed Marknote and ran the “Import from KNotes” command, but it created an empty notebook. Does that mean my KNotes data did not survive the upgrade to Debian 13?

I would assume the KNotes data is stored somewhere hidden down in your user account directory (and not removed by a upgrade / simple package removal).

But that has to answer someone that has more internal knowledge where that data is actually stored. So that you can look for that file (if it is a file) and if it is still there for its size, or even your backups if you have one that includes the hidden “dot” stuff.
@jlskuz maybe?
If it is still there and doesn’t look empty that could be a Marknote bug.

For Debian to not only remove but purge everything from KNotes completely on upgrade by default seems weird. But I have never used Debian myself.

Edit: It is stored in a Akonadi database, found this:

Don’t forget to chance the id number at the end of the SELECT ... to the number it shows for you at “text/x-vnd.akonadi.note”. If the resulting “/tmp/outraw.txt” is a empty zero byte file then unfortunately nothing is there anymore, if it is not then Marknote probably has a bug.

I am not a developer of KNotes or Markdown so cant help here, sorry.
