I just upgraded to Ubuntu 12.10 from 12.04. But I cannot use WebApps. In fact there is no sign of them anywhere. Firefox and Chromium are not prompting for integration.

I tried re-installing both browsers/webapps plugin of each, but no luck. Out of curiosity, I tried to install unity-webapps-preview through terminal, apt-get reported that this operation is going to need 127mb. After installation, restarting session, nothing.

I re-ran the unity-webapp-preview in terminal and SURPRISINGLY it again asked me that this operation is going to need 58mb. After Installation, nothing.

Firefox is showing the unity-webapp plugin in Extensions but in Preferences there is noting like Unity settings or options for exceptions in General tab (as I seen in some threads).

Chromium is not even showing the plugin in Extensions nor in the settings. Really need help. I know there is a reported bug but it is mostly about the complains that the webapps are not working as they should but in my case they don't seem to exist.

EDIT: The out put of gsettings list-recursively | grep webapp is:

com.canonical.unity.webapps allowed-domains @as [] com.canonical.unity.webapps dontask-domains @as [] com.canonical.unity.webapps index-update-time 43200 com.canonical.unity.webapps integration-allowed true com.canonical.unity.webapps preauthorized-domains ['amazon.ca', 'amazon.cn', 'amazon.com', 'amazon.co.uk', 'amazon.de', 'amazon.es', 'amazon.fr', 'amazon.it', 'www.amazon.ca', 'www.amazon.cn', 'www.amazon.com', 'www.amazon.co.uk', 'www.amazon.de', 'www.amazon.es', 'www.amazon.fr', 'www.amazon.it', 'one.ubuntu.com']

What do you mean by re-ran the unity-webapps-preview? Please edit your question to include the output of gsettings list-recursively | grep webapp. –  edwin Jul 1 '13 at 19:26

Can you please add the output of dpkg --get-selections | grep webapps as well? Thanks :) –  Seth Jul 1 '13 at 22:38
downgraded to 12.04 from 12.10? upgraded to 13.04 from 12.10? Typo. Please clarify. –  Yet Another User Dec 17 '13 at 21:37

The latest version for Ubuntu (stable) is 13.10 and not 12.10, do a clean install to that version and post your feedback, remember to do a backup of your data.

I use Trusty, so I cant test this solution, but I found this PPA for webapp integration for Quantal(12.10) https://launchpad.net/~webapps/+archive/preview

Visit this link, and select on "View package details" and find and download integration packages for your browser, and then install "unity-webapps-2.0-0quantal1" (or you may do this first before downloading integration packages for your browser)

Hope this works.
