TYPO3 Upgrade from v9 to V10 lazy loading error

Question

I’m trying to update a TYPO3 site from version 9.5.30 to version 10.0.0.

I have the following error:

(1/1) #1549446998 LogicException TYPO3\CMS\Core\Cache\CacheManager can not be injected/instantiated during ext_localconf.php loading. Use lazy loading instead.

Answer 1

Do you really update to TYPO3 10.0.0? You can and should update directly to version 10.4 (10.4.20 as of today).

According to the TYPO3 bug tracker (#88843, #88975), there were problems which have been fixed already a long time ago.
