Occasionally Amahi [https://www.amahi.org/apps applications] fail to install properly. This is often noted by error messages in the application install log (/var/log/amahi-app-install.log).
======= app install end @ 2014-05-03 07:42:43 -0500 ==========</pre></small>
Other times, you may receive notice in the Dashboard (Amahi 7 ONLY).

We take these seriously and have incorporate incorporated additional error checking/prevention methods. Unfortunately they don't catch everything.

<div style="border: 1px solid #A3B1BF; padding: .8em 1em; background-color: #E6F2FF; margin: 0px 1em;">'''DISCLAIMER:''' The steps below should '''ONLY''' be attempted by advanced users. If you don't know what you are doing, recommend you seek professional assistance or you could break your HDA!</div>
<!--== MANUAL CLEAN UP ==An '''NOTE:''' We will use '''owncloud''' as an example of the application that failed to install. A web app install was unsuccessful, but it appears partially installed. This often happens and repeatedly trying to install without clean up results in multiple failed attempts. For example, 4 failed attempts of [https://www.amahi.org/apps/owncloud ownCloud] would create ''owncloud'', ''owncloud1'', ''owncloud2'', ''owncloud3''. To return your HDA to a safe state for another install attempt, the following may help:* Check Navigate to the ''Network'' tab, ''DNS Aliases'' section in the Amahi Dashboard** Make note of the URL name(s)** Remove each entry for the failed application by selecting ''Delete''* If the app has a database, execute the following command: hda-create-db-and-user -d owncloud<ul><li>The next steps must be done from the command line as ''root'' user:</li><ul><li>Navigate to /etc/varhttpd/hdaconf.d and determine file(s) to remove</webli> ls -al<li>Remove each ####-apps directory app.conf (substitute the number for #### and look URL name for the app) file</li> cd /etc/httpd/conf. d rm -rf 1001-owncloud.conf** The application short URL is the name of the directory rm -rf 1002-owncloud1.conf rm -rf 1003-owncloud2.conf rm -rf 1004-owncloud3. conf<li>Then as ''root'' user, restart apache</li> For examplesysemctl restart httpd<li>Next, Adminer would be adminer.navigate to /var/hda/web-apps</li> cd /var/hda/web-apps** <li>Remove the each app directory</li> rm -rf owncloud rm -rf owncloud1 rm -rf owncloud2 rm -rf owncloud3</ul></ul>* Check Finally check the HDA database ''hda_production'' (hda_production, apps ''webapps'' table). ** Look to see if there is an entry for the each app that failed to install correctly.** Remove the row(s) that row if it existsexist for the app (i.e.id 4, 5, 6, and 7)<br />:'''EXAMPLE'''<blockquote><pre>MariaDB [hda_production]> select id,name from webapps;
