How to install Slack on Ubuntu
Ubuntu gives you two main ways to get the chat app on your desktop. The first method uses the built-in Snap package manager that ships with Ubuntu. Snap puts the app in an isolated box and runs updates in the background. You can open the Ubuntu software center, search for the app, and click install. Your system handles the download and adds an icon to your desktop menu.
The second method uses a Debian package file from the official vendor website. You download the package file through your web browser and open it with your installer. This setup adds the vendor repo to your system software list. When you run system updates, Ubuntu checks that list and pulls new chat versions. Both paths ask for root rights on your local machine to finish the setup.
Choosing between Snap and Debian packages
Your choice between Snap and Debian packages changes how the app reads local files. Snap packages use strict rules to limit what folders the chat app can read. This setup keeps the app away from your local SSH keys and system files. Sometimes these strict rules can block screen sharing on older Linux display servers. Most modern Ubuntu releases use Wayland or updated rules that fix screen sharing issues.
Debian packages run with the same local rights as your main desktop user. The app can read any file in your home folder without asking you first. It also starts up a bit faster on older laptops with slow disks. Teams that want simple background updates usually pick the Snap method. Teams that manage every package through central system scripts often prefer the Debian package.

What local chat setups leave open during incidents
Once the chat app runs, engineers use it to coordinate live production fixes. Team members paste database queries and shell commands into channels during an outage. They also use chat integrations to approve production changes or trigger deployment scripts. Local package setups only control how the chat app runs on the laptop. They do not control what happens when an engineer runs a shared command.
When a developer copies a query from chat into a terminal, big risks appear. A native database login only checks who logs in at the start. It does not check what each SQL statement or shell command does in flight. One bad command from a chat thread can drop a table or leak data. Without field masking that rewrites emails, phone numbers, or card numbers, raw data spills into chat.
Add runtime guardrails and masking beside your databases and APIs
Login rules, role grants, and CI checks govern who connects to your stack. Yet any allowed script, engineer, or AI agent still runs commands with the full scope of its role. For workloads on Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes, SSH, or internal HTTP services, hoop.dev sits inline in the protocol beside the service as an open-source proxy, a sidecar for your database or API. On every production query an agent or human runs, hoop.dev decides whether to pass, mask, block, or escalate it for review.
Before a query runs, hoop.dev guardrails check the statement against your rules, an AI Analyzer you configure can score intent or hold risky calls for human approval, and hoop.dev data masking rewrites sensitive fields in responses in memory. Explore the MIT-licensed project on GitHub.
Frequently asked questions
Does the Ubuntu desktop app update on its own?
Yes, both the Snap version and the Debian package support background updates. Snap updates run on their own, while Debian updates run with your system updater.
Why is screen sharing blank on my Ubuntu machine?
Screen sharing issues usually happen when your display server blocks window capture. Switching your login session between Wayland and Xorg often fixes the black screen.
Can I sign in to multiple workspaces on Linux?
Yes, the Linux desktop app lets you log in to many workspaces at once. You can switch between different team accounts using the left sidebar menu.
