Describe the bug I installed Kasm Workspaces Community Edition on my Ubuntu 18.04 workstation, followed by the Signal Desktop image. When I run Signal in my user workspace, it displays the message: "Signal desktop will no longer support your computer's version of Linux soon. To keep using Signal, update your computer's operating system by Sep 4, 2023. Learn more."

Why isn't this workspace presenting a supported version of Ubuntu (20.04 or 22.04) to Signal Desktop?

To Reproduce Steps to reproduce the behavior:

1. Install Kasm Workspaces Community Edition.
2. Install Signal Desktop image.
3. Run Signal Desktop.
4. See "Signal desktop will no longer support your computer's version of Linux soon. To keep using Signal, update your computer's operating system by Sep 4, 2023. Learn more."

Expected behavior Signal Desktop should not complain the OS it is running on its air to expire.

The signal image is build on the ubuntu focal (20.04) base (https://github.com/kasmtech/workspaces-images/blob/develop/dockerfile-kasm-signal#L2) But, remember containers still use the kernel from your host.

So, my guess is that Signal is detecting the old kernel from 18.04 and giving you this warning since ubuntu 18.04 reached end of standard support last month.
