Isso resulta de a instalação do kubuntu-desktop falhou em dependências não atendidas . Eu acho que perdi meu desktop kubuntu após a instalação do mysql 5.6. Recuperei a área de trabalho instalando o kubuntu-desktop e akonadi-backend-mysql que depende do mysql 5.5.
Quando recuperei o desktop, o MySQL 5.6 anteriormente instalado foi removido e esses dois arquivos não foram encontrados no diretório /var/run/mysqld/ .
/var/run/mysqld/mysqld.pid
/var/run/mysqld/mysqld.sock
Ainda tenho os arquivos de configuração
/etc/mysql/my.conf
/etc/mysql/conf.d/my5.6.conf
e os bancos de dados no diretório de dados
/var/lib/mysql/
Eu terei que instalar o MySQL 5.6, mas minha preocupação é que o akonadi-backend-mysql não funcione com o 5.6. Eu encontrei esse tipo de bug relatado . Aqui estão alguns dos meus detalhes:

Então, minha pergunta é
akonadi-backend-mysql ? Minha distro é o Kubuntu 14.04 LTS.
