Problème MàJ vers 20.0.4

Nextcloud installed on a Debian 10.07

Upgrade Nextcloud to 20.0.4

I have this issue :
Doctrine\DBAL\Exception\DriverException: An exception occurred while executing ‘UPDATE oc_filecache SET mimetype = ? WHERE (mimetype <> ?) AND (mimetype <> ?) AND (name COLLATE utf8mb4_general_ci LIKE ?)’ with params [70, 70, 2, “”]: SQLSTATE[HY000]: General error: 1206 The total number of locks exceeds the lock table size

comment résoudre ce problème de MàJ svp ?

This error has been reported and discussed so often in this forum, that you should find dozens of matches using the search function of this forum. So try to use it to find an answer on your question :wink:

I don’t find dozens of matches but only 4 …and I don’t find any help :frowning:
