The problem is the underscore. Use x86\textunderscore 64
or x86\_64
.

Don't forget your architecture is not i386, but x86\textunderscore 64. Better to use \texttt{\$(uname -i)} instead of manually specifying this

I also change tt
to \texttt
. Alternative you can use \ttfamily
. For more information about this topic read l2tabu
Quoted from l2tabu:
Why not use obsolete commands? Obsolete commands do not support
LATeX2ε’s new font selection scheme, or NFSS. {\bf foo}
, for
example, resets all font attributes which had been set earlier before
it prints foo in bold face. This is why you cannot simply define a
bold-italics style by {\it \bf Test}
only. (This definition will
produce: Test.) On the other hand, the new commands
\textbf{\textit{Test}}
will behave as expected producing:
Test. Apart from that, with the former commands there is no
‘italic correction’, cf. for instance halfhearted ({\it
half}hearted
) to halfhearted (\textit{half}hearted
).
