Discord installed via snap won't launch the app. It just gives me this screen (see screenshot) and lets me choose between "Ubuntu (deb)", "Linux (tar.gz)" or "I'll figure it out". The last one quits the application. I had to install the deb to be able to launch the application.

When using Discord, I can't properly exit the application. File > Exit either does nothing or makes the window go 'black' (Discord's background colour, really) and then reloads Discord, with the 'black' screen still there in another window.

Image of the latter case

Closing the app obviously (as expected) leaves Discord running in the background (though the indicator doesn't work). Using kill on the Discord PID (which I find with top) successfully kills the app, then I can reload it as normal from the Dash.

Hey, I'm trying to quit discord installed via snap and can't do it. I need to use killall Discord (sometimes twice because it restarts itself). I'm trying to quit it by right clicking the tray icon and selecting "quit".

Some more info:
discord 0.0.4 52 snapcrafters
This is on Solus Linus

I have installed Discrod application on Ubuntu 18.04. When I run it, it spams log with several messages per second like this:

audit[17638]: AVC apparmor="DENIED" operation="ptrace" profile="snap.discord.discord" pid=17638 comm="Discord" requested_mask="trace" denied_mask="trace" peer="unconfined"

The above are the main bulk. Then there are few like the following sprinkled around:

AVC apparmor="DENIED" operation="open" profile="snap.discord.discord" name="/proc/2750/cmdline" pid=17638 comm="Discord" requested_mask="r" denied_mask="r" fsuid=1000 ouid=0

not all compose key sequences seem to work with the snap
combinations like √ or some music notes don't seem to work

An OTA update to Discord pops up this now...

I get the B&W Emojis only on Discord. I don't understand why, I'm using Noto Color Emoji font and I'm on Ubuntu 18.04 LTS. They usually work on every apps that I have but on Discord I still get the B&W Emojis (they are showed correctly in the title bar).

Is something missing ? or is it related to the app?

I have Discord installed as Snap on Ubuntu 16.04, including snapd-xdg-open. Yet I am unable to directly open links from Discord. I have to copy and paste them manually into the browser.

Please let me know whether this is already a known issue, or this is wrong place to report such an issue.

Edit: Running xdg-open from the commandline works fine.

See title

Meanwhile when I run package:

Ubuntu 16.04. Installed from snap.

Discord crashes at startup with:

failed to create prefix path: /tmp/snap.rootfs_3knyfv/var/lib/snapd/lib/vulkan/icd.d: Permission denied

Tried reinstalling, purging configurations and installing mesa-vulkan-drivers. No help.
The files that the discord seems to be looking for are located at
/usr/share/vulkan/icd.d

I was having a look through the snap of Discord and noticed that there are a lot of libs included. Why is this? Most of the libs look like they have nothing to do with Discord and would definitely be present on a normal user's install.

Including so many libs might be the reason that the snap of Discord doesn't seem to want to follow my system theme (and also cause other problems with incompatibilities with the system and those libs).

Hello!

It seems like this snap does not have access to my steamapps folder. I often attach screenshots from certain games to Discord. (~/.steam/steam/steamapps/common/Rust/Screenshots f.i.)

Expected behaviour
Attach any file that your user owns successfully. Either with drag and drop or the attach file menu.

Current behaviour
Attaching files from for instance .steam makes Discord angry and it will not upload the file. Seems to be related to missing access.

Reasoning for the expected behaviour
Discord is a voice and chat application made for gamers. Users will share pictures from their games.

Current workaround
Copy picture to ~ before attaching to Discord.
Remove picture from ~ after sending.

It seems like the snap does not include a font with emoji support.

While discord mostly use their own built-in emojis, it is possible that certain people or applications use standard emojis instead. Using the snap you'll only see a square instead of the expected emoji.

Distributor ID: Ubuntu
Description: Ubuntu 16.04.3 LTS
Release: 16.04
Codename: xenial

Discord isn't running at startup with "Open Discord" enabled under LINUX SETTINGS -> SYSTEM STARTUP BEHAVIOR.

When trying to use any Discord RPC enabled application together with the Snap images of Discord the rich presence doesn't show up. As soon as you switch to the Debian package provided by Discord on their website everything works as expected.

Tested on Ubuntu 18.04 LTS with Discord Snap Version 0.0.4

I got a pop up asking me to download either the .deb file or the .tar.gz file. It won't let me use it if I click "I'll figure it out".

I ran # snap refresh, and everything's up-to-date. In addition, according snap info discord, last refresh was yesterday.

$ snap run discord
/snap/discord/64/bin/desktop-launch: line 23: /home/adam/.config/user-dirs.dirs: Permission denied

I also have the Deb installed.

I think it's similar issue with #30

It's works smooth on chrome

And this is the Discord snap package on the same OS

So definitely it's not an OS related issue. Probably the snap package has some missing parts for emojis

The non-snap discord has a normal linux mint menu, but this one is different, anyway to fix it?

Hi everyone,
I have daily crashes on my machine apparently caused by Discord, here are the logs attached. At 11:40, I get a full crash then a restart of my machine with a purple screen (but no login window). I would be grateful to anyone that could point me in the right direction. Thanks a lot.

Logs - Failed reboot.txt

Similar to #3 , I get an empty Discord window but this time I get this when clicking the 'update now' button in the top right (it looks like the Firefox Download logo, but it's green) and updating via that. I get the new Discord come up but also an unclose-able blank window even if I close the working Discord client. Presumably snapd alone should be handling updates, is there an easy way of disabling in-app updates?

audit[6291]: AVC apparmor="DENIED" operation="ptrace" profile="snap.discord.discord" pid=6291 comm="Discord" requested_mask="trace" d (I can't see the rest of the line through systemctl and I can't open the file in Text Editor (it's too big) and cat and nano can't seem to read it (is that normal?)) is repeated many times in /var/log/journal/system.journal making it 100MB for just a few days of logging. The /var/log/journal directory is over 4GB.

Expected Behavior

Clear audio on receive.

Actual Behavior

Audio cuts in and out, infact there is more silence than audio.

Steps to Reproduce the Problem

1. sudo apt-get install snapd
2. sudo snap install discord
3. Wait it to update then connect to voice with another user and try receiving.

Specifications

• Version: 1 Apr 2018 because there isn't a clear in app version number. Especially when launcher can be different version from actual electron app.
• Platform: Ubuntu 16.04 x64
• Subsystem: What subsystem?

Screenshots

Debug log

I would attach the voice debugging log I enabled in the settings but it isn't specified where I can find that too.

discordlinux/support#18

To my mind, it would make more sense if the contact field were https://github.com/snapcrafters/discord/issues instead of [email protected] (which I presume is from when Martin had snapped Discord and not transferred it over).

I enabled every permission, & restarted the app. Still not there.

sudo snap disconnect discord:process-control core:process-control
sudo snap disconnect discord:system-observe core:system-observe

Both tell me that these are not connected but Discord still sees the processes on my computer? 🤔

On install, under settings, the checkbox under Linux Settings -> System startup behaviour is enabled, but

$ grep -r X-GNOME ~/snap/discord/
$ 

then you disable it and

$ grep -r X-GNOME ~/snap/discord/
/home/john/snap/discord/79/.config/autostart/discord-stable.desktop:X-GNOME-Autostart-enabled=false
$ 

and then enable it again

$ grep -r X-GNOME ~/snap/discord/
/home/john/snap/discord/79/.config/autostart/discord-stable.desktop:X-GNOME-Autostart-enabled=true
$ 

i have a couple of folders mounted from ntfs partition and i am denied access when trying to open them
this might related to PR-30

I have refreshed the snap to the latest rev 86.
I have tried removing and installing again.
Have done more than one reboot cycle.
Running discord from cli exits nearly instantly exit code 1 with no output.

I'm trying to get discord to run on my Raspberry Pi Model 3 b but for some reason the command line install doesn't work
"sudo snap install discord
error: cannot install "discord": snap not found"
The first command is lifted directly from the snapcraft store, but for whatever reason it seems to think Discord doesn't exist
I'm running both the latest version of Raspbian and snap so I have no idea what the issue is

(be gentle I'm new)

After installing the Discord snap on 18.04 daily, I get the error below when trying to run it.

https://github.com/qwertyquerty/pypresence

Plugin using API works well via installed .deb, but not in snap. Tried the following in snap, but still got a file not found error

After some research I found some snap plugins which opened up a few more permissions, which did not work - at least with Ubuntu 18.04 (since it's referencing Unity, I assume this worked on earlier versions).
snap connect discord:system-observe :system-observe snap connect discord:unity7 :unity7

Plugin in question is: https://github.com/ToppleKek/discord-rhythmbox-plugin which works perfectly if .deb is installed.

System is Ubuntu 18.04

Distributor ID: Ubuntu
Description: Ubuntu 16.04.3 LTS
Release: 16.04
Codename: xenial

When clicking "Quit Discord" from the Unity panel in the top right, the Discord window pops up, but doesn't close. Clicking "Quit Discord" repeatedly doesn't work either.

Icon changes path between some Discord upgrades and that makes (at least on kde) that shortcuts on panels become invisible until deleted and created again.

I've seen this issue in other snap upgrades, mostly on Discord recently, but it's definitely an issue on snaps as a whole.

Discord seems unable to use the IME (in my case, Anthy) and hence I can't type Japanese characters (copying in/out works just fine, but it's annoying). Japanese characters also appear as boxes, though it seems to be issue #8 (which I'm not entirely sure if it's the fonts or not, I'm only using whatever build was readily available in the snap repo a few days ago).

Also I noticed Discord is not using the native open dialog box which makes me wonder if it's related (it may mean a library issue), though that can also just be a red herring.

Running Ubuntu 16.04 64-bit.

Whenever I click on a link in discord, nothing happens. Nothing is opened in the browser.

If I use the discord debian package, all good.

I'm not sure what's causing this only with the snap version. I'm on Kubuntu 18.04 and use google chrome (install from apt).

I'd love some direction on how to debug this. I know there is very little information, so it's a hard guess.

Reviving #1 on Kubuntu 18.04. Did stuff break again?

Like that thread's OP, I have snapd-xdg-open installed, and xdg-open [url] works in a console, yet clicking any links in Discord that would normally open in the browser does nothing.

As with the old issue #49 . Discord snap is out of date yet again: 0.0.9 is required and 0.0.8 is currently on snap.

The latest build (0.0.8) seems to be 12 days ago:
https://build.snapcraft.io/user/snapcrafters/discord/479130
Can someone please ran and check the build again?

i have noticed certain fonts are missing in the snap version

Discord was running like a bag of crap, UX freezing for a few seconds, etc. So when I found it also spamming /var/log/syslog to death, it was off to the chopping block...

Except, even after removing, it was still spamming up my logs.

It seems the program continues to live even after it's been removed. Shouldn't the removal process also kill off any running programs from the snap being removed?

The Discord AppIndicator doesn't work out-of-the-box on Ubuntu 17.04. As I said here, I think the likely reason is because Ubuntu changed the value of XDG_CURRENT_DESKTOP from Unity to Unity:Unity7 for Ubuntu 17.04.

@flexiondotorg 's patch for the Dropbox Deb was:

# Fix indicator icon and menu on Unity environments. (LP: #1559249)
new_env = os.environ.copy()        
if 'Unity' in os.environ.get("XDG_CURRENT_DESKTOP", '').split(":"):
  new_env['XDG_CURRENT_DESKTOP'] = 'Unity'

Presumably we could do a similar thing in a scriptlet for the Discord snap?
