[Sugar-devel] Running Sugar Activities

[James Cameron]

Hello Soham,

You have an unusual configuration;

- a PyGObject introspection module in /home/soham/.local instead of
  /usr, (caused by using pip instead of isntalling the python-gi
  package),

- the Sugar Toolkit is installed in /usr/local, (caused by building
  Sugar Toolkit from source without specifying a prefix),

I don't know what problems that may cause.  You're very brave.

However, answering your traceback, the TelepathyGLib namespace can be
installed on Ubuntu 18.04.3 by typing;

	sudo apt install gir1.2-telepathyglib-0.12

You didn't say what version of Calculate you had installed, but as the
traceback referenced Python 2 perhaps it was Calculate-45.  How did
you install this activity?

Latest is Calculate-46, which is Python 3.

On Ubuntu 20.04, the dependencies for the Calculate-46 activity could be;

python3, python3-sugar3, python3-gi, python3-dbus, gir1.2-glib-2.0,
gir1.2-gtk-3.0, gir1.2-pango-1.0, gir1.2-rsvg-2.0,
gir1.2-telepathyglib-0.12, and python3-matplotlib

So after you install gir1.2-telepathyglib-0.12 you may have to install
other packages.
