Failed upgrade 5.5 to 10.3

Hi - I upgraded from mysql 5.1 to MariaDB 5.5 That went perfectly fine.

I then tried upgrading from 5.5 to 10, and the install went okay but the database refuses to start. I tried various paths (mysql 5.1-mysql5.5-mariadb5.5-maria10) but the result is always the same:

Obviously the problem is '2018-10-14 19:45:57 0 [ERROR] InnoDB: Table `mysql`.`innodb_table_stats` not found.' from the log below

BUT - if I create this file in mariadb5.5 it then complains about the structure.

Is the a 5.5 compatible version of this table of this table that will work with 10.3?

It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware.

We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail.

Server version: 10.3.10-MariaDB-log key_buffer_size=33554432 read_buffer_size=2097152 max_used_connections=0 max_threads=2502 thread_count=0 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 25709168 K bytes of memory Hope that's ok; if not, decrease some variables in the equation.
