indeed, to sum up you can create the directory by yourself and set the permissions correctly (even if not used, apps-external requires correct permissions for the installation process to end).
FYI, I created a bug report about it and the ownCloud team is working on it.
I am having the same issue and am stuck. I noticed that there was a /var/www/html/owncloud/apps/external directory. Shouldn’t it be using it, instead of the non-existant /var/www/html/owncloud/apps-external directory? Is there a config file somewhere that I can point it the right place?
Bear with me, I am new to this. Here is the contents of /var/www/html/owncloud/config/config.php:
$CONFIG = array (
'instanceid' => 'ocnbvtm2fzca',
Am I looking at the wrong file?
Also, the apps-external directory was never created by the install. It did create /var/www/html/owncloud/apps/external with a bunch of files and directories in it.
I installed version 10.4.0. Is the install really that broken that is trying to reference directories that it was supposed to create but didn't???
