I'd argue it is necessary for golang 1.19.<br><br>In order to fix this, the code change needs to go into pgzip and libpod needs to be rebuilt.<br><br>-rt</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Apr 2, 2023 at 6:51 AM Antonio Cebrián <<a href="mailto:ancebfer@gmail.com">ancebfer@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<div>Podman cannot load images compressed with gzip. Uncompressed
images or bzip2 compressed images work right therefore it seems to
be a problem related to gzip handling.</div>
