How to Get a list of Installed ‘web-apps’ and Remove them in Ubuntu 12.10?


Although it is very tempting, due to few reasons, I have decided to wait a few more months (hopefully) before I give a go at the new Ubuntu Unity’s ‘web-apps’ features. I did install few of these apps, but encountered few glitches here and there, it doesn’t seem like it is quite there yet (at least in my ‘short’ experience).

Anyhow, whether you use this feature or not, if you have installed some of these ‘web-apps’ through Firefox, then it can be a bit difficult to get rid of them later, as there is no way to get a list of currently installed ‘web-apps’ through the ‘Online Accounts’ tool, as it does not show all the installed apps.

But luckily, you can use a simple trick in the Terminal window, to get a list of currently installed ‘web-apps’. And once it gives you the list, then you can use the usual ‘apt-get remove …’ command to get rid of them easily.

For that, please follow the below steps.

Step 1: Finding them.

Open your Terminal window and enter the below command.

dpkg --get-selections |grep unity-webapps

This as shown below, should give you a list of currently installed ‘web-apps’.

Note: ‘libunity-webapps0′ and ‘unity-webapps-service’ are core libraries of ‘web-apps’. So make sure not to remove them.

Step 2: Removing them.

Let’s say I wanted to get rid of the ‘Launchpad’ web-app, then I’ll use the below command.

sudo apt-get autoremove unity-webapps-launchpad

You can remove multiple ‘web-apps’ at the same time too. For that, make sure to add a ‘space’ between each package’s name, as shown below.

sudo apt-get autoremove unity-webapps-launchpad unity-webapps-youtube

Also remember to replace these package names with the ones installed on your Ubuntu OS as well (of course). That’s it.
