[Bug 1720442] Re: Software (gnome-software) crashes after several seconds. Entirely unusable.

2017-10-25 Thread Dan Bright
Certainly looks like you've identified the issue, great!

Hopefully as far as Gnome Software is concerned, the fix would be
relatively trivial then - i.e. handling the case where the "type" and
"id" fields are empty ...

2017-10-24 Thread Robert Ancell
Thanks Dan! Looks like snapd can return broken snaps we're not handling. The 
JSON for the broken snap is:
{
 "apps":[{"snap":"nominal-roll-generator","name":"node-service"}],
 "broken":"cannot read snap \"nominal-roll-generator\": cannot find installed 
snap \"nominal-roll-generator\" at revision x20",
 "channel":"",
 "confinement":"",
 "contact":"",
 "description":"",
 "developer":"",
 "devmode":true,
 "icon":"",
 "id":"",
 "install-date":"0001-01-01T00:00:00Z",
 "installed-size":0,
 "jailmode":false,
 "name":"nominal-roll-generator",
 "private":false,
 "resource":"/v2/snaps/nominal-roll-generator",
 "revision":"x20",
 "status":"active",
 "summary":"",
 "tracking-channel":"",
 "trymode":true,
 "type":"",
 "version":""
}

It's the blank type and id fields that is causing GNOME Software to
crash. The "broken" field is a new one I haven't seen.

Think you're nailing it. The output references the snap I was attempting
to create one evening, before I abandoned the experiment and deleted it
(as referenced above). It was called "nominal-roll-generator".

Hi Dan,

Could you attach the raw output after running this command? It will
access snapd and get the list of snaps you have installed. The
stacktrace is suggesting you have a snap without a name. I've seen
similar issues show up in automatic crash reports but never been able to
work out why this might occur.

$ nc -C -U /run/snapd.socket
GET /v2/snaps HTTP/1.1

That's great, no problem at all, I'll keep the system as-is.

Just give me a shout if and when you need more details or testing;

If you could keep the system in that state to help debugging the issue
that would be great. The backtrace has the debug info now and we are
looking at the problem but might need more details later or somebody to
test a potential fix one we have one, you should have updates on that
bug in the next days in any case.

2017-10-19 Thread Dan Bright
Oops sorry about that - thought I'd reinstalled the debug symbols before
the last backtrace, but clearly not. Please find new backtrace,
attached.

I'm keeping this current installation with a view to helping with
diagnosis of this issue. As far as I'm concerned, that's fine for the
moment (I very rarely use the GUI to manage software packages). But,
being that it's quite possible that a fresh install would solve the
issue (reinstalling and missing/corrupt packages, for example), then let
me know and I'll just wipe and reload at some point.

Essentially, I'm not bothered about this issue being investigated/solved
for my own purposes, but if you feel it may be useful to pursue this
possible bug in terms of the wider community, then I'm more than happy
to keep the current install as-is for the moment, with a view to
assisting with that process.

As regards the snapping of my own application, thanks for the heads-up
about the forum. I did raise a question there several weeks ago, but in
the end it just wasn't worth the time/hassle to sort it out. I'm sure
the issues I were having were just the result of me somehow messing it
up, and the app in question was just a demo thing that I doubt anyone
would really be interested in. It was just a preliminary experimentation
using snap really (a very exciting distribution method, that I look
forward to playing with again soon!).

Hi,

Yes, the issue is still occurring, with every attempt to run gnome-
software resulting in the same outcome (a crash).

I'm bang up-to-date with all system and software updates.

Yes, snap is working fine from CLI. I just installed/removed a snap to
test, with no issue whatsoever.

Please find a further backtrace attached.

Thanks!

Thanks for the details and sorry for taking time getting back to you. Do
you still get the issue? Could you maybe install the libglib2.0-0-dbgsym
as well?

Is the snap service working correctly for you? Can you snap install some
snap from a command line?

[Bug 1720442] Re: Software (gnome-software) crashes after several seconds. Entirely unusable.

2017-10-01 Thread Dan Bright
While looking through the backtrace, I noticed the references to
libgs_plugin_snap.so. That reminded me, I was messing around with
snapcraft a couple of weeks ago, trying to snap an app of mine (it
didn't end well).

I'm wondering if I inadvertently broke something, possibly removing a
critical snap related file in error (I didn't intentionally remove or
change anything outwith my own created snap files, but wouldn't rule out
having done so erroneously as a possibility).

Either way, in that scenario a resultant gnome-software crash probably
wouldn't be a desired/expected outcome, so I'd imagine the bug would
nevertheless stand, but this is some additional context in case it's
useful.
