It seems that your migrating MySQL database from 5.1 to 8.0.36 is wrong.

The `0` is retrieved from `database_version` record in `system` table but the
value is never `0`.
The following is from database for Trac 0.12.x
[[[
mysql> SELECT * FROM `system`;
+--------------------------+-------+
| name | value |
+--------------------------+-------+
| database_version | 26 |
| initial_database_version | 26 |
+--------------------------+-------+
2 rows in set (0.03 sec)
]]]
The value of `database_version` is depended on the Trac version:
[[[
| database_version
------------+------------------
Trac 0.12.x | 26
Trac 1.0.x | 29
Trac 1.2.x | 41
Trac 1.4.x | 45
Trac 1.6.x | 45
]]]
