Error while loading SQL upgrade file "index.php.sql" PS upgrade 1.7.1.0

[omine]

Upgrading from 1.6.1.12 to 1.7.1.0 stuck on "Disabling modules now..."

 

Before the "Database upgrade" action, 2 errors are displayed:

Error while loading SQL upgrade file "index.php.sql".

 

Error while loading SQL upgrade file "index.php.sql".

 

(see attached file)

 

Despite the error, i tried to access other pages but the authentication automatically redirects to BackOffice login page.

 

I can see the version was changed to 1.7.0.1 but cannot enter .

 

The login seems authenticating but something forcing back to login page again.

 

 

 

When enabling the debug mode:

PrestaShopDatabaseException in Db.php line 744:Table 'pe_jp_db.ps_authorization_role' doesn't exist<br /><br /><pre>
SELECT `slug`,
`slug` LIKE "%CREATE" as "add",
`slug` LIKE "%READ" as "view",
`slug` LIKE "%UPDATE" as "edit",
`slug` LIKE "%DELETE" as "delete"
FROM `ps_authorization_role` a
LEFT JOIN `ps_access` j ON j.id_authorization_role = a.id_authorization_role
WHERE j.`id_profile` = 0</pre>

I found the sql files into upgrade/sql folder

 

This folder is inside a folder named "autoupg-inst-58e507769c2d0"

 

After execute some obvious SQL files, i've entered on BackOffice.

 

However, of course, nothing is working and have millions of errors, things not loaded, missing files, etc. 
I give up.. this version is too far to be reliable.
