Slack refusing to start

Question

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

[winston] Attempt to write logs with no transports {"level":"debug","message":"getLogger: Winston backend does not support child logger"}

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

https://downloads.slack-edge.com/releases/linux/4.27.156/prod/x64/slack-desktop-4.27.156-amd64.deb

OUTDATED proposal : I confirm also that this version of Slack seems to have problems.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

or

sudo snap refresh slack --channel=insider/edge

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

Answer 2

Downgrading seems to work, as a workaround for now;

sudo apt install slack-desktop=4.26.1

Answer 3

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]
Version=1.0
Type=Application
Name=Chromium Slack chat
Comment= Slack chat app
Exec=chromium --app=https://yourslackworkspace.slack.com
Icon=/home/user/.local/share/applications/slack.png
Path=
Terminal=false
StartupNotify=true
StartupWMClass=yourslackworkspace.slack.com

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

Answer 4

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:

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

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

Example:

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.

Answer 5

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.

Answer 6

I recently had the same issue. If you want to disable Apparmor for slack until it is resolved then you can find the profile in:

/var/lib/snapd/apparmor/profiles/snap.slack.slack

Then create a symbolic link to this in the /etc/apparmor.d/disable directory:

cd /etc/apparmor.d/disable && sudo ln -s /var/lib/snapd/apparmor/profiles/snap.slack.slack .

This then allowed me to start slack.
