Epubcheck binary does not execute

[José Lemos Neto]

Using the epubcheck package from ubuntu stable repo, it just doesn't execute, i'm running on a podman container from the official ubuntu image at dockerhub, installed the package normally through apt. (i got no further verbose)

/usr/bin/epubcheck: line 1: $'PK\003\004': command not found
/usr/bin/epubcheck: line 2: syntax error near unexpected token `)'

     �� ��A�áj��n�0஽�a=�>�I��D�m�$9M��)ۉˎ��!�E�G��Hʹe�\'

It just doesn't execute, giving me strage errors on the binary and displaying some stdout about META-INF that (should?) be related to the epub i'm scanning, you can read some information about my system on this paste of inxi -bGI: System:
