[TYPO3-english] Re: [TYPO3-core] Announcing TYPO3 CMS 6.2.27 LTS, 7.6.11 LTS and 8.3.1

[Dennis Hoffland]

Hello,

I tried to update to 6.2.27 but ran into the following error in the Upgrade Wizard (Install Tool):

Update failed!
SQL-ERROR: Incorrect table definition; there can be only one auto column and it must be defined as a key

SQL-statement:

ALTER TABLE tx_realurl_pathcache ADD uid int(11) NOT NULL auto_increment;

Repeating the procedure as suggested here https://forum.typo3.org/index.php/t/214123/ only results in the same error.

Any help is much appreciated (6.2.27 is a security fix)

Kind regards,

Dennis
