Installing Slack on Linux
The proper way to install Slack is to download the installer for your Operating System on the Slack website.
However I realized my Slack client was not really up-to-date.
When installing Slack, a daily cronjob is installed automatically which is supposed to configure the automatic updates.
However for some reason on my computer the cronjob while running never installed anything.
It is only when I started to encounter problems with my Slack client that I realized I had an outdated version.
How to verify if Slack is correctly configured?
The configuration should create the following file: /etc/apt/sources.list.d/slack.list
If this file is missing, you can use the following steps to install it manually.
Configuring APT for Slack updates
There is a tutorial and an automatic script that you can find here: https://packagecloud.io/slacktechnologies/slack/install
But if you want to do it step by step, here is how to do it.
- First add the repository key
wget -O - https://packagecloud.io/slacktechnologies/slack/gpgkey | sudo apt-key add -
- Enter your password and you should see the following result.
--201X-XX-XX XX:XX:28-- https://packagecloud.io/slacktechnologies/slack/gpgkey
- 100%[===================================>] 3,86K --.-KB/s in 0s
201X-XX-XX XX:XX:30 (59,8 MB/s) — [3954/3954]
OK
- Create the file /etc/apt/sources.list.d/slack.list with the following content
deb https://packagecloud.io/slacktechnologies/slack/debian/ jessie main
- Run sudo apt update
- Run sudo apt install slack-desktop
- That's it, Slack is now installed and will update itself automatically with APT.
