[Koha] #1005 - Can't create table `koha_library`.`aqbasket`

Hi,
we were using koha 3.18 running on ubuntu 14.04 since 2015. 2 weeks back the
server refused to respond.
i now backed up the data using mysql dump and re-installed koha 17.11
running on ubuntu 16.04 and mariadb database.
i am now trying to import the backup of our former server using phpmyadmin,
it starts to import then, the following error pops up. what to do. below is
the error:
