That is just telling you that you have a typo after mariadb in your command pip install mariadb Kernel because there is no matching item for your distribution in PyPI that matches ‘'Kernel’.
I think according to here, you meant type something more along the line of python3 -m pip install mariadb_kernel? Note the underscore, no space, and no capitalized K.
