Gcc-multilib install error


installation gcc-multilib for compilation of 32 bit (sudo apt-get install gcc-multilib) app gives an error
Package gcc-multilib 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 ‘gcc-multilib’ has no installation candidate
