Try searching that error on internet. It seems to have different solutions and I don't know your setup so unfortunately I am not able to help you.

It crashes.

I'm using Gnome and Wayland here but it seems to be down to the use of 'xdg-screensaver'. The 'xdg-utils' Arch Linux package has 'perl-net-dbus' and 'perl-x11-protocol' listed as optdepends for 'xdg-screensaver'. It's only an issue if your system makes use of 'xdg-screensaver'

I do not have this issue with indicator on my 2 pcs. I don't think that caffeine contains a single line of perl code, so I this this is highly improbable that it needs some perl modules. Maybe you are using some panel/desktop environment that uses perl for that. I have no idea, using lxde and xfce4 here, both on x11.

Also this package states optdependency on libayatana-appindicator, without it i have this error

Traceback (most recent call last):
  File "/usr/bin/caffeine-indicator", line 32, in <module>
    gi.require_version('AyatanaAppIndicator3', '0.1')

    raise ValueError('Namespace %s not available' % namespace)
ValueError: Namespace AyatanaAppIndicator3 not available

@micwoj92 one more issue. 'caffeine-indicator' will fail to work if 'perl-net-dbus' and 'perl-x11-protocol' are not installed. I get the following error messages without those two packages installed. I suggest they should be added as optdepends for 'caffeine-indicator'.

Disregard previous comment, I'll apply your patch later today.

I added py_modules=[] to per the suggestions I got out of the bug report I linked to in my previous message and that solved the issue. My patch for it is here:

I also let the caffeine developers know about the issue here:

The issue seems related to this

@micrwoj92 I'm seeing the following build error message below on two separate systems. Do you know what might be the issue?

 error: Multiple top-level packages discovered in a flat-layout: ['etc', 'share', 'translations'].

To avoid accidental inclusion of unwanted files or directories,
setuptools will not proceed with this build.

If you are trying to create a single distribution with multiple packages
on purpose, you should not rely on automatic discovery.
Instead, consider the following options:

1. set up custom discovery (`find` directive with `include` or `exclude`)
2. use a `src-layout`
3. explicitly set `py_modules` or `packages` with a list of names

To find more information, look for "package discovery" on setuptools docs.
