[BUG] ValueError: Namespace AppIndicator3 not available

[timocarnill]

when I try to run pulsemeeter (installed with: sudo pip install pulsmeeter on Pop!_OS 22.04, with python 3.10.4, it doesn't open. When I run it in the terminal it says: Traceback (most recent call last): File "/usr/local/bin/pulsemeeter", line 5, in from pulsemeeter.main import main File "/usr/local/lib/python3.10/dist-packages/pulsemeeter/init.py", line 1, in from .interface import MainWindow File "/usr/local/lib/python3.10/dist-packages/pulsemeeter/interface/init.py", line 2, in from .main_window import MainWindow File "/usr/local/lib/python3.10/dist-packages/pulsemeeter/interface/main_window.py", line 26, in gi_require_version('AppIndicator3', '0.1') File "/usr/lib/python3/dist-packages/gi/init.py", line 126, in require_version raise ValueError('Namespace %s not available' % namespace) ValueError: Namespace AppIndicator3 not available

Hello. You are missing the libappindicator of your distro. You should be able to install it by writing sudo apt install libappindicator-dev in your terminal. If that didn't work for you or you need more help, you might be interested in joining our Discord: https://discord.gg/ekWt9NuEWv . Closing this issue because it isn't an issue with the software.

Same error on Ubuntu 22.04 LTS. Installing libappindicator-dev does not help:

Traceback (most recent call last):
  File "/home/reichardt/.local/bin/pulsemeeter", line 5, in <module>
    from pulsemeeter.__main__ import main
  File "/home/reichardt/.local/lib/python3.10/site-packages/pulsemeeter/__init__.py", line 1, in <module>
    from .interface import MainWindow

    from .main_window import MainWindow
  File "/home/reichardt/.local/lib/python3.10/site-packages/pulsemeeter/interface/main_window.py", line 26, in <module>
    gi_require_version('AppIndicator3', '0.1')
  File "/usr/lib/python3/dist-packages/gi/__init__.py", line 126, in require_version
    raise ValueError('Namespace %s not available' % namespace)
ValueError: Namespace AppIndicator3 not available

I think the according package for this OS would be libayatana-appindicator3-dev? But unfortunately it doesn't solve the issue.

Unkle Bonehead seems to have posted a solution on our Discord:

(8.6.2022) sudo apt install gir1.2-appindicator3-0.1

Please confirm if it worked so we can put it in our install instructions.

@Fl1tzi I was just having the same error and installing gir1.2-appindicator3-0.1 fixed that issue for me. I am running Kali though so I had to manually install as the repo does not include that package. I am going to look through the rest of the issues though to see if I can find my new one to keep from hijacking another thread.

To answer the question, I think adding that to the install instructions may be a good idea as it got rid of the error for me.

Installing gir1.2-appindicator3-0.1 works on Ubuntu 22.04 LTS. :+1:

(sry for the late reply)

Hello,

I experienced the following error when trying to install the libappindicator3-dev package :

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libayatana-appindicator3-1 : Conflicts: libappindicator3-1
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

Trying to install gir1.2-appindicator3-0.1 instead solved the issue. Could please the wiki be updated accordingly ?

Also the Ubuntu (apt based) item of the table of contents doesn't work.

Thanks

You would need to look into what your distribution packages it as.

"Package 'gir1.2-appindicator3-0.1' has no installation candidate" what do i do? tried everything

if you're on debian (amd64) run:

ARCH=amd64
curl http://ftp.us.debian.org/debian/pool/main/liba/libappindicator/gir1.2-appindicator3-0.1_0.4.92-7_$ARCH.deb \
    -o gir1.2-appindicator3-0.1.deb && sudo dpkg -i gir1.2-appindicator3-0.1.deb
rm gir1.2-appindicator3-0.1.deb

if that doesn't work initially, try: sudo apt --fix-broken install
