FATAL ERROR: Upgrade failed

Checked my syslog file and found this

Mar 3 14:33:41 localhost /etc/mysql/debian-start[1131]: Looking for ‘mysqlcheck’ as: /usr/bin/mysqlcheck
Mar 3 14:33:41 localhost /etc/mysql/debian-start[1131]: Version check failed. Got the following error when calling the ‘mysql’ command line client

Mar 3 14:33:41 localhost /etc/mysql/debian-start[1131]: FATAL ERROR: Upgrade failed

How I can fix it? Thanks.
