I typed the following command to install gcc-multilib:
sudo apt-get install gcc-multilib
but I got the following error message:
Reading package lists... Done
Building dependency tree
Reading state information... Done
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
How do I fix it ?
