    Running Unity Hub 3.0.0-beta.5 on Ubuntu 20.04. If I have a separate
    /tmp
    partition mounted as
    noexec
    , it produces the following error on the terminal

    Code (csharp):
    1. A JavaScript error occurred in the main process
    2. Uncaught Exception:
    3. Error: /tmp/.org.chromium.Chromium.SuiCGP: failed to map segment from shared object
    4.     at process.func [as dlopen] (electron/js2c/asar_bundle.js:5:1846)
    5.     at Object.Module._extensions..node (internal/modules/cjs/loader.js:1138:18)

    The fix to this is to not mount
    /tmp
    as
    noexec
    , but this is poor security practice. It's mounted that way for a reason—being able to execute files in
    /tmp
    can open all kinds of security vulnerabilities. Unity Hub, should really put its temporary executables somewhere else.

    Hi there!
    Could you please report it as a bug using the Bug Reporter within the Hub? We need to check the log to understand what's going on.
    To do so, go to Account Settings > Troubleshooting > Report a bug
