<p>Hej,<br>
<br>
this is really weird. I am able to download the file via a browser. However, I still get the same error msg during the build process. I regenerated the resolv.conf as Andreas suggested. Unfortunately, that didn't help.<br>
<br>
So, if I am able to access the file in the browser and make gives me the error that it can't find the file... that means...(?)<br>
<br>
Anyway, thank you very much for the fast replies.<br>
<br>
<br>
Best regards,<br>
Maik<br>

<p>Hej there,</p>
<p><br>
</p>
<p>I am getting this strange (MD5 related?!) error during the build process and unfortunately, I don't have any idea how to approach it. It seems like I am not able to download the external data. Maybe the hashtag is not correct?! Did anyone encounter this
problem before?</p>

<p>Thank you very much for your help in advance.<br>
