I uninstalled iceweasel because I was trying to get a different version of Firefox and it didn't work out so I reinstalled it. Then I did that again but this time it won't reinstall. I tried Apt-get install iceweasel and it says reading package lists...done Building dependency tree Reading state information... done Package iceweasel is not available, but it is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source.
I have no idea what to do and it's very important that this is fixed soon.
