After upgrading distro, graphical interfaces of Trackma doesn't work

[coolboymew2]

After upgrading my distro I've found myself unable to open Trackma anymore. I tried reinstalling and it's telling me

error: externally-managed-environment

I searched online and apparently I have to install and use pipx. I did, and I reinstalled Trackma and all of the graphical interfaces refuses to work. Curses just tell me I have a package missing, normal Trackma works in terminal

Any ideas?

Thanks

You're definitely missing dependencies. Not sure where you got the pipx recommendation from, but what actually is your distro and how did you install trackma and which version?

[coolboymew2]

MX Linux. I just upgraded from 21.3 to 23 through their guide. Trackma has not been opening since

As said, I tried reinstalling through pip3 and I got

`error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
    python3-xyz, where xyz is the package you are trying to
    install.

    If you wish to install a non-Debian-packaged Python package,
    create a virtual environment using python3 -m venv path/to/venv.
    Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
    sure you have python3-full installed.

    If you wish to install a non-Debian packaged Python application,
    it may be easiest to use pipx install xyz, which will manage a
    virtual environment for you. Make sure you have pipx installed.

    See /usr/share/doc/python3.11/README.venv for more information.

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.

I have no idea what this is about, but from your comment, I assume everything python broke?

[qyot27]

Python didn't break, it was a deliberate change to how pip installs packages. It tells you that at the very end of the message: hint: See PEP 668 for the detailed specification.

But, you can override it by using the --break-system-packages option when using pip install (no, that name's not hyperbolic at all :sarcasm:), although that might require a newer version of pip. Applications with limited scope and few dependencies like trackma (especially few dependencies not already handled by the system repo) aren't the ones that are going to cause the kind of conflicts that this policy change in Python/pip is intended to prevent.

[coolboymew2]

I got scared by the hyperbolic "--break-system-packages", but it looks like just running pip3 as usual with that command did the job and it's opening again

Thanks for the advice

@coolboymew2 I experienced the exact same errors as you. I've figured out the correct way to install this using pipx.

pipx install --system-site-packages trackma
pipx inject trackma urwid
pipx inject trackma pyqt5

@z411 you might want to add this to the README.
