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 [url][http://www.percona.com/doc/percona-server/5.6/management/udf\_percona\_toolkit.html[/url]](http://www.percona.com/doc/percona-server/5.6/management/udf_percona_toolkit.html%5B/url%5D) 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
