[Otas]

Hello,

Im using virtualBox on Ubuntu 18.02 and trying to launch nextcloud on VirtualBox using centos7 but im getting the same error “Internal Error”

Im doing all the same like this tutorial: https://docs.nextcloud.com/server/15/admin_manual/installation/source_installation.html

This error shows on nextcloud 12, 13, 14, 15. I tried even owncloud but i get error what server cant write config file, but nothing more.

I am new at this and can someone help? I dont know where to find log’s. Thanks.

If you have same error on some many version of nextcloud, lay be error is on an other way. Config in your server.
Are you sure you have the right to write, with the good user ?
