The code below considers the LANG always as en_US:
~_{~
system identity: 605a0996-b0e8-411d-8691-795a1c0ea4bf}
~~

If I use the LANG 'pt_BR.UTF-8', it will break the UUID:
~~~

1. LANG=pt_BR.UTF-8 subscription-manager identity | head -1
   identidade do sistema: 605a0996-b0e8-411d-8691-795a1c0ea4bf
   ~~~

The current code:
~_{~
UUID=$(subscription-manager identity | head -1 | awk '{print $3}')}
~~

Then, the UUID will be 'sistema:'.

I believe if we change the code, it will avoid this kind of issue:
~_{~
UUID=$(subscription-manager identity | head -1 | awk -F':' '{gsub("^ ","",$2); print $2}')}
~~
