Kodi upgrade 19.4 to 21

I installed “aptitude” and it gives me solutions :

aptitude install kodi-inputstream-rtmp
The following packages will be updated:
  kodi-inputstream-rtmp{b}
The following partially installed packages will be configured:
  kodi
1 packages updated, 0 newly installed, 0 to be removed and 0 not updated.
You will need to download 77.7 kB of archives. After unpacking, 28.7 kB will be used.
The following packages have unmet dependencies:
 kodi-inputstream-rtmp : Depends on: kodi-api-inputstream (>= 3.2.0) which is a virtual package, provided by: 
                                  - kodi (2:20.1+dfsg-1) provides kodi-api-inputstream=3.2.0, but 3:20.5-4~bookworm is installed

                         Depends: kodi-api-inputstream (< 3.3.0) which is a virtual package, provided by:
                                  - kodi (2:20.1+dfsg-1) provides kodi-api-inputstream=3.2.0, but 3:20.5-4~bookworm is installed
 
The following actions will resolve these dependencies:

     Keep the following packages in their current version:
1) kodi-inputstream-rtmp [19.0.1-3~bullseye (now)]
