You get this error because your map store has a PeerAdmin card that was created using Composer 0.16 or earlier. The cards are not compatible, therefore, when the Kli tries to remove the card, it cannot. The quickest solution is to completely remove the file system map storage. Currently, the file system map storage will always be located in ${HOME}/.composer, so to delete it you will do
rm -fr ${HOME}/.composer
