<div dir="ltr">Hi Xavier,
<div><br>
</div>
<div>There's definitely a problem interrupting the connection
with the server. The fact it works sometimes means it's
inconsistent.</div>
<div><br>
</div>
<div>Can you please try to download such files several times out
of snap and snapd, to see what the error is?</div>
<div><br>
</div>
<div>Per my note above, we had a bug in snapd which prevents the
real error from being shown. We're always showing the digest
mismatch instead, which will of course happen if the download
is interrupted before its end.</div>

As written on the bug report + some part feedback emails you
received some weeks earlier, it seems you ignored one part of the
issue. Yes, it seems the network is failing. However, snapd
consistenly fails in my case for downloading, while other tools,
like wget and curl can download bigger files, many times, without
ever getting one failure. They are more robust in difficult network
situations it seems.<br>
<br>
So either the store connection side is fragile or snapd isn't robust
enough while other tools cope with those conditions just fine
(without any warning/debug message telling that they are retrying).<br>
Cheers,<br>
Didier

<div>Hi all,<br>
<br>
</div>
I don't know exactly where to find all the data you are
asking for, but this is what I found (below). Related to
the network, as a test, I just downloaded the linux
kernel .tar.xz (98MB) using python requests and worked
properly. I am not using any proxy at all.<br>
<br>
</div>
The "snap install" worked with hello-world but failed with
webdm, docker and nmap. I didn't try anymore.<br>
<div><br>
</div>
<div>Let me know if you want any further test.<br>
</div>
<div>Regards<br>
Xavi<br>

</span>This version of snapd
has a mixup of expected vs
actual hash, this is<br>
fixed in git. Sorry for the
confusion.<br>
<br>
I would love to see the
actual file that got
downloaded, that is<br>
probably tricky because
currently we delete those
iirc. It would be<br>
good to have the file to see
if its garbage or a mostly
valid squashfs<br>
with some garbage in between
or something else. Also size
would be<br>
interessting etc.<br>
<br>
