I am trying to install Owncloud server on a fresh install of Ubuntu 16.04 and have been following these instructions from Digital Ocean and it has gone flawlessly up until the command
$ sudo apt-get install owncloud
So I tried running
$ sudo apt-get install owncloud-files
Which something installed, but it didn't do the installer as expected per the Digital Ocean instructions
To be clear, I have done all of the steps leading up to the install of owncloud.
$ sudo curl https://download.owncloud.org/download/repositories/stable/Ubuntu_16.04/Release.key | sudo apt-key add -

Package owncloud is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
owncloud-files
E: Package 'owncloud' has no installation candidate
That is everything that happens when I follow the steps, it still says there is no 'owncloud' installation candidate.
The problem here is that ownCloud recently dropped the owncloud meta-package (that can be harmful in environments with multiple applications hosted simultaneously). The difference with the owncloud-files package is described in the docs:
owncloud-files (recommended): This package installs only ownCloud. It does not install Apache, a database, or any PHP dependencies.
owncloud: This package installs ownCloud, complete with all dependencies.
So, basically, you downloaded and installed ownCloud on your system (you'll see it living under your /var/www/owncloud dir.) - but now it's missing its dependencies. You'll need to install them manually; you can see a list in: https://doc.owncloud.org/server/10.0/admin_manual/installation/source_installation.html#install-the-required-packages:
sudo apt install -y apache2 mariadb-server libapache2-mod-php7.0 \
php7.0-gd php7.0-json php7.0-mysql php7.0-curl \
php7.0-intl php7.0-mcrypt php-imagick \
php7.0-zip php7.0-xml php7.0-mbstring
After the installation, you'll be prompted with the apache wizard you were missing from the DigitalOcean tutorial. From there you'll be able to customize the server installation. In case you need more info on how to complete the process, see: configuring the apache server and completing the installation
