I forgot to delete the Iceweasel on my Kali Linux before installing Firefox. The firefox installation is failed as expected. I removed the sources.list entry of the firefox and conducted "apt-get update". However, I got a message of "the package firefox-mozilla-build needs to be reinstalled, but I can't find an archive for it". The apt-get command does not work properly anymore.
Later, I fixed the problem by issuing the following commands :
sudo dpkg-reconfigure firefox-mozilla-build --force
sudo dpkg --purge --force-all firefox-mozilla-build
After that, I perform "sudo apt-get update", the error message gone.
That's all! See you.
