Initially an ownCloud instance provides a minimal set of applications after installation (Files, Pictures).
Many applications are available as “one click” installations that are automatically downloaded, installed, and “enabled” via the ownCloud administration user account. Other applications have to be downloaded from the '''[https://apps.owncloud.com/ ownCloud AppStore]''', installed, and "enabled" manually.
====Manual Removal====
Even though an ownCloud application is "Disabled" (administration user only) the application program code remains in a the ownCloud apps directory. Sometimes it may be necessary to permanently remove the application program code from the ownCloud instance. Additionally there are some ownCloud database entries that have to be removed also.
* Ensure that the application is "Disabled" in the Apps listing.
* All application entries in the ownCloud MariaDB database have to be removed this can done by using Amahi "phpMyAdmin".
* In the database table "oc_appconfig", find all entries having the name of the application in the "appid" column.
* Remove those entries. This step is '''extremely''' important especially if another version of this app is to be trialled later.
* Now the application is permanently removed from ownCloud.
<br>
In order to allow multiple instances of different version releases of ownCloud on the same Amahi server naming changes to the main ownCloud application directory and database names have been implemented.
* The location where the actual ownCloud application is stored has changed to "/var/hda/web-apps/owncloudx/html" (where "x" is the major release number). For example for ownCloud release version 68.1.0.5 the directory is now named "owncloud6owncloud8".
* The ownCloud database user ID, password, and name have changed in the same manner.
