Note it's not *the* failing snap but *a* failing snap. Every "snap
install" here is failing on my setup when they are more than a
couple of MB. This is why I posted as such in the instructions on
the bug.<br>
<br>
So, with curl -v -L, with the same snap than on the bug report, here
are the results: <a class="m_2017832842691031138moz-txt-link-freetext" href="http://paste.ubuntu.com/23583801/" target="_blank">http://paste.ubuntu.com/<wbr>23583801/</a><br>
I did 10 successful downloads in a row. This snap is 23MB.<br>
<br>
I did retry with the new revision (49), 32MB.<br>
Tried 10 times with curl, 10 successful and complete downloads (one
is <a class="m_2017832842691031138moz-txt-link-freetext" href="http://paste.ubuntu.com/23583847/" target="_blank">http://paste.ubuntu.com/<wbr>23583847/</a>), with expected size and
checksum.<br>
Tried 10 times with snapd, got hashsum mismatch 10 times. Download
stops after few KBs up to few MBs.<br>
<br>

<div>If you file a bug and a developer asks for

<div>Is it the case? Did you ever

</span> Yes, as mentioned. I never got any
failure with any of them and I did retry
multiple times in loop when I saw the snapd
failures.<br>
wget is in verbose mode by default and I
never got any hint that it was retrying
(just getting the normal download output).<br>
<br>
I did just try a verbose download in curl
(here, an ubuntu 300M image). Here is the
output: <a class="m_2017832842691031138m_2037343581792085072m_557326114865415527moz-txt-link-freetext" href="http://paste.ubuntu.com/23583568/" target="_blank">http://paste.ubuntu.com/235835<wbr>68/</a>.
It seems that curl doesn't complain of any
reconnect.</div>

<div><br>
</div>
<div>You are downloading an image from an
arbitrary server on the internet unrelated to
the problem we're trying to debug.</div>
<div><br>
Can you please attempt these several curl
downloads while using the exact same URL that
failed for snapd?</div>

<br>
</span> As a developer asking for more debug information,
can you please paste the exact instructions on how to get
those?<br>

based url with the .snap showing up in the logs to get the
exact same assets I pasted snapd information on. However,
curl -v returns (output stripped out):<br>

I guess that's due to the macaroon exchanged system and
I'm not authorized or something else?<br>
