Some applications keep "uninstalling" themselves.
For example, I installed Google Chrome via Ubuntu After Install and it was working great. In the middle of a normal browsing session, I noticed that the Chrome icon in the dock had turned grey. Didn't know what it was, so I closed my Chrome window, and then the icon in my dock disappeared. I searched my applications for Chrome, but curiously it had disappeared. When I opened up Ubuntu After Install, it said that Chrome wasn't installed. So I reinstalled it, and it works fine again. But then the problem repeated itself.
This also happened when I downloaded and installed the Whatever .deb file (wrapper for Evernote). I downloaded the .deb, installed it via GDebi. I was able to find the application when I searched for it, however it would not open, and now has dissapeared from my application search (even though the .deb file is still in the same place).
Any thoughts?
which google-chrome
