Hi! I understand that you're seeing the error "app/im.status.session/x86_64/master not installed" and you'd like help resolving it. Just to clarify, are you trying to install the Session app on your ChromeOS device, or is this happening when you try to run it? Also, did you attempt any installation method so far (like Flatpak, AppImage, or other sources)?

That way, I can guide you with the most relevant steps. Meanwhile, I’ll explain a common approach based on this error message:

1. This error often means the app or a particular architecture-specific build (x86_64) isn’t installed or recognized.

2. Because you’re on ChromeOS with WebKit, apps like Session usually install through Flatpak or from official sources. Manual or incomplete installs may cause this issue.

Here’s a step-by-step to try:

1. Check if you have Flatpak installed on your device: ChromeOS supports Linux apps via Crostini. If you have the Linux terminal enabled, run in terminal:

<br> flatpak --version<br>
If not installed, you can install Flatpak via Linux terminal first. Let me know if you need help with enabling Linux on your ChromeOS.

2. Install Session app via Flatpak: Using Flatpak is often more straightforward for managing versions and dependencies. Run this command in your Linux terminal:

<br> flatpak install flathub app.im.status.session<br>

3. Run the app after installation:

<br> flatpak run app.im.status.session<br>

4. If you see errors during install: Check your Linux disk space or update Flatpak:

<br> sudo apt update && sudo apt upgrade -y<br> flatpak update<br>

5. If you had previously tried other methods such as AppImage or manual, try removing any leftover files or uninstalling incomplete installations, then reattempt Flatpak.

If you can tell me what steps you have already tried or what specific installation method you used, I can tailor the troubleshooting further.

Are you comfortable using the Linux terminal on ChromeOS? Would you like me to walk you through enabling Linux on ChromeOS and then installing Session properly?

Let me know!
