HI,

I’m having some problems updating XtraDB cluster:

etting up percona-xtradb-cluster-server-5.6 (5.6.26-25.12-1.trusty) …

- Stopping MySQL (Percona XtraDB Cluster) mysqld [OK]

- Percona XtraDB Cluster 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-xtradb-cluster/5.6/management/udf\_percona\_toolkit.html[/url]](http://www.percona.com/doc/percona-xtradb-cluster/5.6/management/udf_percona_toolkit.html%5B/url%5D) for more details

- Stale sst\_in\_progress file in datadir mysqld \* Starting MySQL (Percona XtraDB Cluster) database server mysqld \* State transfer in progress, setting sleep higher mysqld \* The server quit without updating PID file (/var/lib/mysql/.pid).  
[fail]  
invoke-rc.d: initscript mysql, action “start” failed.  
dpkg: error processing package percona-xtradb-cluster-server-5.6 (–configure):  
subprocess installed post-installation script returned error exit status 1  
dpkg: dependency problems prevent configuration of percona-xtradb-cluster-56:  
percona-xtradb-cluster-56 depends on percona-xtradb-cluster-server-5.6 (\>= 5.6.26-25.12-1.trusty); however:  
Package percona-xtradb-cluster-server-5.6 is not configured yet.

dpkg: error processing package percona-xtradb-cluster-56 (–configure):  
dependency problems - leaving unconfigured  
No apport report written because the error message indicates its a followup error from a previous failure.  
Errors were encountered while processing:  
percona-xtradb-cluster-server-5.6  
percona-xtradb-cluster-56  
E: Sub-process /usr/bin/dpkg returned an error code (1)

Someone can help me on this?

thanks.
