Indeed, these packages are not included in Debian 10 "Buster".
It seems that the only databases supported by Kexi in Buster
are MySQL and PostgreSQL.
If you don't actually use Sybase or XBase in Kexi, then you can simply
remove these 2 packages from your Additional Software, and the other
packages should be installed again.
