Slack crashes on Debian

snap
1

Executing slack on the terminal emulator does not produce any output nor start Slack. The only thing is the following Syslog record:

out 15 16:58:36 galadriel kernel: traps: slack[15792] trap int3 ip:5631583631a5 sp:7fff019e0850 error:0 in slack[5631563e6000+531d000]

What I’ve done

  • Reinstall slack
  • Delete ~/.config/Slack
  • Installed slack.deb, which worked

I also have the same issue since several days ago. I am using Debian 10.

3

perhaps the patch from

has not landed in the debian 5.2 kernel yet ? (there should be some debug hints to find if you are affected by this in the other thread)

As far as I can tell this issue is not related to Mounts broken with kernel 5.2. Besides that, I’ve other snaps using volumes:

Facing same problem on debian 10 buster. Slack is simply not working with snap.
Tried to install slack using debian package it works but at the time of installation throwing an error for gconf2***

Uninstalled the latest version of slack
and then installed the edge (older - weird) version and guess what, its working fine.

Command to remove latest and greatest slack:
sudo snap remove slack

Command to install the edge version:
sudo snap install slack --classic --channel=edge

Hey guys I raised ticket on slack site about above issue and they have helped me to get it up and running.
It was really quick reply from Slack support team (Wojtek).

Wojtek confirmed that there is known bug in current version and it will be fixed in next release meanwhile slack’s latest snap package can be used using below command.

slack --no-sandbox

Thnx,
Sudhir Dhumal

Confirming that slack --no-sandbox did start Slack.
