after having problems with the update to the version V3.9.0 two days agao, I’ve restored my installation from a backup to the version V3.8.1.
Today Matomo showed me the new version V3.9.1 in the user interface and I tried to update from V3.8.1 to V3.9.1.
Unfortunately, the update failed again with the following error message:
Matomo encountered an error: Call to undefined method Piwik\Plugin\Manager::getPluginDirectory() (which lead to: Circular dependency detected while trying to resolve entry ‘Piwik\Twig’)
As a test, I ran the archive job “core:archive”. That worked without any problems and without errors. With V3.9.0 this job failed with several errors.
Nevertheless, I decided to restore the version V3.8.1 from my backup, waiting for an newer Version.
