Comment 3 for bug 1049077

Same problem here but in Trusty:

However, I found a problem with redis configuration shipped with Zentyal. While trying to lauch the redis-server instance for ebox (/etc/init/ebox.redis.conf):

# sudo -u ebox /usr/bin/redis-server /var/lib/zentyal/conf/redis.conf

*** FATAL CONFIG FILE ERROR ***
Reading the configuration file, at line 307
>>> 'vm-enabled no'
Bad directive or wrong number of arguments

It seems to be a wrong version of redis that lacks some configuration directives shipped with Zentyal. Commenting out the following on /usr/share/zentyal/stubs/core/redis.conf.mas

vm-enabled no
vm-swap-file /var/lib/redis/redis.swap
vm-max-memory 0
vm-page-size 32
hash-max-zipmap-entries 512
hash-max-zipmap-value 64

You can do an apt-get install -f and end installation (however some other errors appears)
