Public bug reported: Hi all. I've been using Pondus for a long time. After upgrading to 18.04 graph stopped working and the graph button is greyed out. If I hover on the button a hint appears, saying "matplotlib not available". I tried to install matplotlib by "apt install" or pip but definitely I am not a Python guy.
Then I tried to start the program from CLI (Kubuntu Konsole and standart Ubuntu terminal). I got the following message at start up: Exception in thread Thread-1: Traceback (most recent call last): File "/usr/lib/python2.7/threading.py", line 801, in __bootstrap_inner self.run() File "/usr/lib/python2.7/dist-packages/pondus/gui/window_main.py", line 359, in run import_mpl() File "/usr/lib/python2.7/dist-packages/pondus/gui/window_main.py", line 374, in import_mpl from pondus.gui.dialog_plot import PlotDialog File "/usr/lib/python2.7/dist-packages/pondus/gui/dialog_plot.py", line 17, in <module> from matplotlib.backends.backend_gtkagg import FigureCanvasGTKAgg \ File "/usr/lib/python2.7/dist-packages/matplotlib/backends/backend_gtkagg.py", line 14, in <module> from matplotlib.backends.backend_gtk import ( File "/usr/lib/python2.7/dist-packages/matplotlib/backends/backend_gtk.py", line 35, in <module> from matplotlib.backends.backend_gdk import RendererGDK, FigureCanvasGDK File "/usr/lib/python2.7/dist-packages/matplotlib/backends/backend_gdk.py", line 33, in <module> from matplotlib.backends._backend_gdk import pixbuf_get_pixels_array ImportError: No module named _backend_gdk ** Affects: pondus (Ubuntu) Importance: Undecided Status: New ** Tags: matplotlib pondus -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1768183 Title: matplotlib is not available, graph is not shown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pondus/+bug/1768183/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
