Updating Percona MySQL Server

Hi, i’m having some problemas while updating percona mysql server:

Installing percona-server-server-5.6 (5.6.26-74.0-1.trusty) …

  • Stopping MySQL (Percona Server) mysqld [ OK ]

  • Percona Server is distributed with several useful UDF (User Defined Function) from Percona Toolkit.

  • Run the following commands to create these functions:

mysql -e “CREATE FUNCTION fnv1a_64 RETURNS INTEGER SONAME ‘libfnv1a_udf.so’”
mysql -e “CREATE FUNCTION fnv_64 RETURNS INTEGER SONAME ‘libfnv_udf.so’”
mysql -e “CREATE FUNCTION murmur_hash RETURNS INTEGER SONAME ‘libmurmur_udf.so’”

  • See http://www.percona.com/doc/percona-server/5.6/management/udf_percona_toolkit.html for more details

  • Starting MySQL (Percona Server) database server mysqld [fail]
    invoke-rc.d: initscript mysql, action “start” failed.
    dpkg: error processing package percona-server-server-5.6 (–configure):
    subprocesso script post-installation instalado retornou erro do status de saída 1
    Foram encontrados erros enquanto processava:
    percona-server-server-5.6
    E: Sub-process /usr/bin/dpkg returned an error code (1)

What can I do to solve this?

thanks
