1 year ago Hi!
The ImportError has been reported previously, notably in #250, and is a downstream packaging problem requiring Ubuntu (which Pop OS reuses the repositories of) to update their package of LiSP for Ubuntu 22.04.
The downstream bug report for this is here: https://bugs.launchpad.net/ubuntu/+source/linux-show-player/+bug/1987073
According to Wikipedia the team behind Pop OS will be skipping/have skipped having a 22.10 release; which is unfortunate as it would have pulled in the Ubuntu 22.10 repos (which contain LiSP v0.5.3 that fixes the problem).
The appimage error has also been reported previously - in #238 - details about that can be found there.
At the moment, the solution is to install LiSP v0.5.3 from source: https://github.com/FrancescoCeruti/linux-show-player/wiki/Install#manual-installation
Hi, I'm on the most recent version of POP! OS. Tried to install the software via "apt-get", had no success, LiSP would not even launch. This is what i got back in the terminal
Traceback (most recent call last): File "/usr/bin/linux-show-player", line 3, in <module> from lisp.main import main File "/usr/lib/python3/dist-packages/lisp/main.py", line 30, in <module> from lisp import modules File "/usr/lib/python3/dist-packages/lisp/modules/__init__.py", line 23, in <module> from lisp.ui import elogging File "/usr/lib/python3/dist-packages/lisp/ui/elogging.py", line 28, in <module> from lisp.ui.widgets import QDetailedMessageBox File "/usr/lib/python3/dist-packages/lisp/ui/widgets/__init__.py", line 1, in <module> from .cueaction_combobox import CueActionComboBox File "/usr/lib/python3/dist-packages/lisp/ui/widgets/cueaction_combobox.py", line 25, in <module> from lisp.cues.cue import Cue, CueAction File "/usr/lib/python3/dist-packages/lisp/cues/cue.py", line 25, in <module> from lisp.core.fade_functions import FadeInType, FadeOutType File "/usr/lib/python3/dist-packages/lisp/core/fade_functions.py", line 32, in <module> from lisp.core.util import FunctionProxy File "/usr/lib/python3/dist-packages/lisp/core/util.py", line 22, in <module> from collections import Mapping ImportError: cannot import name 'Mapping' from 'collections' (/usr/lib/python3.10/collections/__init__.py)So I downloaded the appimage. The application launched wonderfully! But when creating a media cue i get the error "Backend not loaded", i went into my preference tab and there is not even a Gstreamer option. How can I solve this?
