When i try to install fastcgi in ubuntu server 12.04 I get the following error: sudo apt-get install libapache2-mod-fastcgi Reading package lists... Done Building dependency tree Reading state information... Done Package libapache2-mod-fastcgi 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 'libapache2-mod-fastcgi' has no installation candidate Any solution?
