I'm having the same problem with 12.04.01 as Eeesy in a previous post.
I use the link in Kubuntu to invoke the installer to 'Install Mozilla Firefox Browser.'
(By 'invoking the installer' I mean K menu-->Applications-->Internet-->'Mozilla Firefox Browser Installer') I go through the installation dialogue boxes, and it indicates
Package successfully installed. After this, I do not seem to be able to locate the link to Firefox. (I have tried: which firefox and which Firefox, neither of which result in a path.)
I have also tried:
sudo apt-get install firefox
[sudo] password for chphunk: Reading package lists... Done Building dependency tree Reading state information... Done Package firefox is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'firefox' has no installation candidate
When I browse the Muon Software Center, it shows Firefox Web Browser as installed. When i select 'More Info', it indicates 'Find in the menu: K --> Applications -->Internet -->Mozilla Firefox Browser Installer.
I just want to run Firefox. Can you offer any guidance here? Thanks in advance.
