Take the 2-minute tour ×  I've made a clean install of 13.04
64-bit on a Dell Vostro 3500 i5 4gb RAM. The apps are working
properly when installed after the Firefox requests, only Gmail
(which was a troubled app for some systems on previous versions
also) doesn't appear on Unity and on the Messaging Menu. I've
tried to reinstall the app via Synaptic, but no results. Would
there already be a way to solve this in 13.04? Thanks in
advance.  share|improve this question  2 Answers 2  In case you
want to retry adding the Gmail Unity webapp from firefox:
execute sudo apt-get purge unity-webapps-gmail, restart firefox
and surf to https://gmail.com. You should see the dialog asking
to install the gmail webapp.  I'm experiencing the same issue,
one thing I've noticed is that the file
~/.local/share/applications/GMailmailgooglecom.desktop was
missing on my system. I created it and populated it with (you
can create it by running unity-webapps-desktop-file
/usr/share/unity-webapps/userscripts/unity-webapps-
gmail/manifest.
