from 30 minutes ago on slack refuses to start on my 20.04 box. Last thing i did before it stopped working was updating firefox to 102.0 but i'm not confident if this is related to it.

I downloaded the recent slack 4.27.154 deb package from their website and installed it through through apt install, however it still refuses to start.

Here's the console output:

> slack 
Initializing local storage instance

I also noticed a strange error when trying to get the help information:

❯ slack --help

Anyone has any idea what the problem is? I'm not finding anything on this stuff in the web.

**UPDATE : July, 8th **

Available working version now from slack is : 4.27.156


OUTDATED proposal : I confirm also that this version of Slack seems to have problems.

as explained by @Iam Strad you can install Slack from snapcraft, unfortunately, it will probably not be enough as it brings you the same version 4.27.154 2022-06-27.

But with snap you can find an older version of slack that is still functional until a better version is published.

sudo apt update
sudo apt install snapd
sudo snap install slack --channel=insider/edge


sudo snap refresh slack --channel=insider/edge

it should bring you version 4.25.1 that could be a temporary workaround .

    Directly from slack support, they propose those two alternatives which are closed from what was proposed on this page : If you're on the Snap Store version you should be able to do this via sudo snap revert slack If you are on the .deb, you can download 4.26.1 here: downloads.slack-edge.com/releases/linux/4.26.1/prod/x64/…

    it fixed the problem after running top and killing Slack processes. Jul 1 at 9:02
  • Just received the upgrade to 4.27.156 but it seems to be still broken. :-(

    4.27.156 is working after I killed all stale slack processes. :tada:

Downgrading seems to work, as a workaround for now;

sudo apt install slack-desktop=4.26.1
  • This worked for me. Thank you. Ubuntu 20.04.

    Thx but didn't WFM (Ubuntu 20.04). After downgrade, running slack from command line no longer outputs [winston] Attempt to write logs with no transports errors after Initializing local storage instance, but slack still doesn't start. Worrying. Don't want to reboot at the mo. so I'll use slack from my browser until I next reboot. Jul 1 at 9:39

As a workaround you could use slack with chromium. In a terminal you could execute: chromium --app=https://yourslackworkspace.slack.com

If that works, create your own desktop file in /home/user/.local/shares/applications for easy access:

[Desktop Entry]
Name=Chromium Slack chat
Comment= Slack chat app
Exec=chromium --app=https://yourslackworkspace.slack.com

I'm running slack with this config, calls, huddle etc works out of the box


For those who have the it installed on apt-get:

In my search for an older version to roll back to, I ended up scouring the flathub code for a url for downloading an older .deb and came across:


Replacing the $version with a version number found on the slack release notes page did the trick.


wget https://downloads.slack-edge.com/releases/linux/4.26.1/prod/x64/slack-desktop-4.26.1-amd64.deb

and then

sudo dpkg -i slack-desktop-4.26.1-amd64.deb

UPDATE: I could have probably saved a lot of trouble by following the dowgrade path for flatpak apps.


I found these problems, my slack was installed by *.deb and yesterday I updated to version 4.27. I solved it by updating the nvidia video card drivers, using the drivers from the nvidia-driver package.
