Package: libllvm5.0
Version: 1:5.0-2
Severity: important

Dear Maintainer,

Can not install libllvm5.0:i386 while libllvm5.0:amd64 already exists in system:

# aptitude why-not libllvm5.0:i386
i   libllvm5.0 Breaks libllvm5.0:i386 (!= 1:5.0-2)


Also, apt message is not very usable:

apt install libllvm5.0:i386
