certtools issue

[amin-prvn]

when I built a Docker file, got this error:

[10/15] RUN certtool --generate-self-signed --load-privkey ca-key.pem --template ca.tmpl --outfile ca-cert.pem:
#0 0.318 Trailing garbage: ` '
#0 0.318 error parsing number: 1

Do you have any idea, how I can fix that?

In this format everything worked.
