Iniciando o servidor de banco de dados MySQL: mysqldinstall: usuário inválido 'mysql'

Question

Eu tenho um problema com o mysql no meu Raspberry Pi executando Linux raspberrypi 3.18.7+ #755 PREEMPT Thu Feb 12 17:14:31 GMT 2015 armv6l GNU/Linux .

Este é o erro que tenho quando executo sudo service mysql start

Starting MySQL database server: mysqldinstall: invalid user 'mysql'

Eu não encontrei resposta em nenhum lugar, então estou perguntando aqui.

versão do mysql: mysql Ver 14.14 Distrib 5.5.41, for debian-linux-gnu (armv7l) using readline 6.2

etc/passwd file:
