• I have checked the issue tracker and have not found an issue that matches the one I'm filing. This should include closed issues.
• This issue doesn't reproduce on web browsers (such as in Chrome). If it does, issue reports go to the Mattermost Server repository.
• I have read the contribution guidelines.

Mattermost Desktop Version

Mattermost Desktop 5.12.1

Operating System

Kubuntu 24.04

Mattermost Server Version

9.6.1

What type of crash did you experience?

System crash (The application quit unexpectedly with no warning, or the operating system reported a crash)

Crash report details

Mattermost Desktop 5.12.1 consistently crashes on Kubuntu 24.04 with the following error:

Error: EIO: i/o error, write
at Object.writeSync (node:fs:774:3)
at Object.writeFileSync (node:fs:2215:35)
at createLogFile (/opt/Mattermost/resources/app.asar/main.bundle.js:223045:10)


I suspect this is caused by the outdated Electron version (22.x) bundled with 5.12.1. Kubuntu 24.04 ships with Linux Kernel 6.14 and Mesa 24.x (Radeon RX 580). Many Electron-based apps using < v26 show similar behavior on this stack.

✔️ **Works fine in Chrome and other browsers**  
✔️ **Issue does not occur on Windows**

Additional Information

It seems the Linux build lags behind Windows/macOS in updating Electron. Could you consider releasing a 5.x patch with Electron >= v26 or backporting the fix from 6.x nightly?

Meanwhile, is there a known workaround for Linux users to avoid this crash?

@skorpions2000 Desktop App v5.12.1 is using Electron v35, so it wouldn't be that. FWIW the next version will be releases with v37 which could fix your issue.

It seems as though there's something in Node failing on I/O, which seems more system dependant. Does the app works on other systems as expected? This isn't something I can reproduce.

[skorpions2000]

@devinbinnie I also couldn’t reproduce the issue. On other systems (like Windows) there are no such problems because the software stack differs.

This time, Kubuntu 24.04 was installed “from scratch.” I performed exactly the same steps as before: installed Mattermost and Steam, launched Counter-Strike 1.6, then closed the game. After that, Mattermost failed to start with the same EIO: i/o error, write. That’s what happened last time, but now everything works fine. The actions were identical.

Honestly, I suspect this could be related to the AMD drivers (GPU: Radeon RX 580, Mesa 24.x). Could it be a Mesa + Electron issue?

[devinbinnie]

Possibly. This is sounding more like an Electron issue than it is a Mattermost issue. I'd check their repo and see if anyone has seen any similar errors.
