in version cqrlog_2.0.5-1_amd64.deb at ubuntu 17.04 the mysql version is deprecated and gives out the error about expecting mysql 5.6 not 5.7 but for ubuntu 17.* and i guess 16* mysql 5.6 is already depricated and no longer possible to install correctly becouse of deprecated dependency's for mysql 5.6.
so mysql 5.6 is deprecated and updated to mysql 5.7 i guess CQRLOG needs to update to mysql 5.7 still to work now and in the near future.
