I suspect, this problem has occured from the time I have installed the anaconda package of python. The following steps helped me to resolve the issue.

Step 1: Restart the machine

Step 2: $ sudo apt-get remove slack

Step 3: Download the latest version of slack from Slack website (Find the latest package here - https://slack.com/): $ wget https://downloads.slack-edge.com/linux_releases/slack-desktop-2.9.0-amd64.deb

Step 4: $ Install the downloaded package using the dpkg utility: sudo dpkg -i slack-desktop-2.9.0-amd64.deb

In step 4, we will witness the following error:

$ sudo dpkg -i slack-desktop-2.9.0-amd64.deb

Answer 2

For me All my programs fail if installed through the Ubuntu app store. If I go to the website and manually install their software from their links then everything works fine.

Doing this fixed this exact issue for me for slack. Just went to the slack site and downloaded the .deb file
