For rails development I need to use the selinium driver.
But then I see this error :
Could not find Firefox binary (os=linux). Make sure Firefox is installed or set the path manually with Selenium::WebDriver::Firefox::Binary.path=
so I tried to install firefox this way :
sudo apt-get install firefox xvfb
but then I see this errror message :
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
firefox : Depends: libstartup-notification0 (>= 0.8) but it is not installable
Recommends: xul-ext-ubufox but it is not going to be installed
Recommends: libdbusmenu-glib4 but it is not installable
Recommends: libdbusmenu-gtk4 but it is not installable
xvfb : Depends: xserver-common (>= 2:1.15.1-0ubuntu2.7) but it is not going to be installed
Depends: x11-xkb-utils but it is not installable
E: Unable to correct problems, you have held broken packages.
How can I take care that I can do the test ?
