authentication on fedora 39 fails

I have a setup with an internal gitlab setup authenticating the mattermost account.

the procedure (which worked until a few days/weeks?) back was:

1. on login screen click GitLab
2. browser opens, you authenticate (or just approve the access permission if already logged in)
3. the mattermost flatpak gets the auth token and you´re ready to chat.

now after step 2 nothing happens, mattermost flatpak does not get anything.

(FYI: firefox/rpm is used here)

quit unexpectitly

Remove i386

It hasn't been supported by Flathub for a while

Systray icon does not appear until GNOME AppIndicator extension is reloaded

After starting Mattermost application using flatpak run com.mattermost.Desktop, the system tray icon does not appear.

If I, while Mattermost is running, use the GNOME Tweaks application to disable the AppIndicator GNOME Shell extension and then enable it immediately after, the system tray icon shows up.

The official Mattermost AppImage release does not exhibit this behaviour, so the issue is specific to the Flatpak release. That is, after starting the AppImage binary, the system tray icon shows up immediately - I do not need to reload the AppIndicator GNOME Shell extension.

I'm running Fedora 32, GNOME Shell v3.36.5, AppIndicator extension v33, and Mattermost v4.5.3 (both Flatpak and AppImage).

Desktop entry not correct

If I record a notification with https://flathub.org/apps/org.freedesktop.Bustle it shows the desktop entry as Mattermost, while it should be the appId com.mattermost.Desktop. This causes some slight breakage with the app icon in the new gnome notifications.

Drop --filesystem=xdg-run/pipewire-0 from manifest

Once Mattermost updates to Electron >= 16 screen sharing should work fine without direct socket access to pipewire.

Feature Request: Autostart support

It would be great to add autostart support, see flatpak/flatpak#118 and https://github.com/flatpak/xdg-desktop-portal/blob/master/data/org.freedesktop.impl.portal.Background.xml

P.S.: Thanks for bringing mattermost to flathub!

Prerequisites update

Hey,

I'm not really knowledgeable in flatpak things so I'm not sure if this can be just my OS version thing, anyway, I'm on Tumbleweed and for me the Prerequisities show a little different than written on the README.

After going through the steps, I found out that the versions required for me no longer are 19.08, but 20.08 for both. Also the electron baseapp distribution is actually wrong, for me when installing the 20.08 of the same image I got an error. It actually doesn't want

flatpak install flathub io.atom.electron.BaseApp//20.08

but this one is needed:

flatpak install org.electronjs.Electron2.BaseApp//20.0

Mattermost on start fails with "write EPIPE"

Right after starting up, mattermost complains with a dialog message showing an internal error "write EPIPE" and clicking any button forces mattermost to close and not reopen.

Opening mattermost from a terminal fixes the issue as it have a tty I believe.

Bug: Launcher starts new instances when hidden in Systray

Steps to reproduce:

• Configure Mattermost to hide in the Systray when the window is closed.
• Restart Mattermost so the changes take effect
• Close the window so only the Systray indicator is left
• Start Mattermost again via the launcher

Observed behaviour:
A new instance is started

Expected behaviour:
The hidden instance is reactivated at its window gets show

No support for arm64 / aarch64

Only amd64 builds are available currently, which makes it impossible to install this Flatpak on devices like a Pinebook Pro.

Recently, aarch64 Linux builds have been added to the upstream CI pipelines, and will be included in the next release: mattermost/desktop#2406

It would be useful if this would be added to the next release on Flathub as well.

update freedesktop runtime to 20.08

Wrong tray notification icon

Hi!

the notificaciont icon that appears in system tray is not correct. It should be the same app icon with a little red circle to show that a new message has been received.

The third icon on the left side:

Can't access yubikey

The flatpak is not able to access my yubikey, when I need it as a second factor for login.

I've set socket=pcsc and device=all not sure which one is the correct one, but after restarting the app it worked fine.

Mouse Cursor Extremely Small on HiDPI Displays Running Wayland

This is similar to this issue here: flathub/im.riot.Riot#341 and might be fixed like it was done for the Signal flatpak here: flathub/org.signal.Signal@831398d

I am running mattermost with the flags--enable-features=UseOzonePlatform,WebRTCPipeWireCapturer --ozone-platform=wayland since I am on wayland and I use scaling. Without those flags all the fonts are blurry. But the cursor still is suuper small and does not get scaled appropriately. It seems to be a common issue as I found several issues about it here.

I can get more information on this if needed.

Redirecting mattermost links to the app is not working

If I click on an link in my browser it fails to find the desktop client to open it with. This was apparently fixed in the native build here: mattermost/desktop#2917

Is there a possibility to fix this in the flatpak build aswell?

No tray icon on Manjaro Gnome

Hi, I am on the latest Manjaro Gnome and installed the Desktop Application; however, when I close it and run it in the background, I would like to have a tray icon to see that Mattermost is still running and if new notifications arrive. Unfortunately, there is no icon. Is this a known issue or did I do something wrong?

UI blurry on Fedora 39 GNOME Wayland HiDPI display

This Mattermost Desktop Flatpak installation produces a blurry display of the UI on Fedora 39 with Wayland GNOME on a HiDPI display.

This happens with and without the file ~/.local/share/applications/com.mattermost.Desktop.desktop being present to overlay the stock .desktop file:

$ diff /var/lib/flatpak/exports/share/applications/com.mattermost.Desktop.desktop ~/.local/share/applications/com.mattermost.Desktop.desktop

4c4
< Exec=/usr/bin/flatpak run --branch=stable --arch=x86_64 --command=mattermost-flatpak --file-forwarding com.mattermost.Desktop --enable-features=WebRTCPipeWireCapturer @@u %U @@

Do other people experience this issue, too?

Can not add a server

Hey there,

I just installed a new system and grabbed mattermost from flathub.

Then tried to add a new server:

Clicked No server configured -> + Add server -> Nothing happens

Not sure if there should be a popup. Unfortunately I can't get a decent log, as running flatpak run com.mattermost.Desktop seems to not attach to the running process. Probably due to the electron wrapper.

"Start app on login" fails

Hi thanks a lot for this packaging, very helpful :)

I'm using it on Linux Mint, here the "Start app on login" setting does not work: it writes an autostart script with the command /app/main/mattermost-desktop --hidden which of course makes no sense from the pov of my system.

I ended up disabling the setting and adding my own autostart entry which calls the same command as the existing menu entry: /usr/bin/flatpak run --branch=stable --arch=x86_64 --command=mattermost-flatpak --file-forwarding com.mattermost.Desktop --enable-features=WebRTCPipeWireCapturer

Would be nice if this autostart command could be adjusted accordingly when added by a flatpak'd app.

Open permissions to the user home directory

Hi,

Right now, Mattermost has open permissions to the whole of user's home directory by default as can be seen in Flatseal.

Comparing that to the permissions of Slack, I believe the permissions are way too open and could be more restricted, like so:

Are there any blockers to implement this?

Must be an issue with the desktop/appdata file

Official support

Ideally the Flatpak would be offically recomended on mattermost.com when users are downloading it. This issue tracks the steps that might be needed for that to happen.

The original proposal to build a Flatpak is here: mattermost/desktop#870. @SemaiCZE Has there been any upstream interest to officially support the Flatpak since then?

An intermediate step could be to have it listed as part of GitHub releases with an unofficial label (like the AppImage). Also it could be mentioned in the install guide.

To do (in no particular order):

• Ensure feature parity between Flatpak and non-Flatpak releases.
• Explore if electron-builder could be used over extracting the tarball.
• I personally think using the tarball is pretty sensible, after all the Flatpak manifest is quite simple.
• See if the icon can be fixed without putting it in the repo.
• Ensure x-checker-data works properly.
• Ask upstream if they have any issues/concerns with officially supporting a Flatpak package.
• Investigate building the Flatpak as part of Mattermost's infrastructure.
• This means there'd be no GitHub repo like we have now. Instead it would look like Mozilla's Firefox Flatpak (notice there's no publisher link).
• See also: flathub/com.obsproject.Studio#136

Cannot connect behind corporate proxy

Hello,

I cannot connect to a Mattermost instance behind a corporate HTTP proxy when using the Flatpak package. This appears to be quite specific to the Flatpak variant; my proxy configuration works

• with normal desktop apps,
• with other Flatpak apps (I can e.g. send me messages with Signal Desktop through the same proxy), and even
• with the Linux binary one can download from https://mattermost.com/download/#mattermostApps/ (the one also listed as source in the flatpak manifest JSON).

It's really just the Mattermost Flatpak which is stuck in the loading spinner behind a proxy (it works if I use a public network, so it's really a proxy issue I guess). I can really just download the binary listed as source in the JSON, run in directly and it works, so I really believe some flatpak stuff is to blame here.

Unfortunately I know neither Mattermost nor Flatpak sufficiently to do any debugging; I'd very much appreciate pointers in the right direction.

Kind regards

No tray icon anymore

I'm not exactly sure since when but I guess since a few days or so
there is no tray icon anymore

it worked before

for testing I tried mattermost-desktop from nixpkgs (version 5.1.0)
and there the tray icon worked

I'm using LXQt with x11
Version 5.3.1 commit: 2c3d80f

Fails to upgrade/install to 4.6.0

I've had this problem for a while where Mattermost never managed to upgrade to 4.6.0 from Flathub.
Tried removing, and running install again (from the command line):
