I am running Kubuntu 13.04 on an HP Pavillion Elite HPE 240f with a 64 bit AMD64 processor. It is a dual-boot configuration with Windows 8.1 Preview.
I use Chromium as my default browser in Linux. On virtually every page I go to, I get a notification to install Unity WebApps plugin. If I click Install plug-in it downloads a file into my
~/Downloads directory. I get a box asking me to Discard or Keep. No matter what I select, nothing happens. I have dozens of copies of this file now. If I select Problems Installing? from the notification bar, it takes me to a web page I can't use.
I have closed and restarted Chromium dozens of times to no avail. I continue to be pestered by this notification bar. I need to get this either installed or removed, I don't care which.
