ON some Mysql setups this problem can happen:
(OperationalError) (1071, ‘Specified key was too long; max key length is 1000 bytes’)
One solution we know it’s working is to add into configuration:
Another user pointed our that he had to disable
STRICT_TRANS_TABLES and was able to complete the installation.
to check the current operating mode run:
SELECT @@GLOBAL.sql_mode, @@SESSION.sql_mode;
