Adding another solution I found for this particular problem. At first, installation seemed ok as I could enable scheduler module and fill (un)publishing dates on content. Although the (un)publishing dates were never saved. It gave a hint that the installation was not made properly.
It failed because of missing folders (default/files/tmp and default/files/translations). The installation made by "composer require" didn't tell where it failed.
