I was trying to install owncloud on Ubuntu 18.04.2 LTS, I followed the instructions online and everything was going smoothly. In the finally step I found this Problem
it says that Can’t create or write into the apps-external directory
I tried to fix this problem by
sudo chown -R www-data:www-data apps-external
but it says no such file or directory.
Really appreciate if anyone could solve this problem:)
