No module named rubber

Asked by Mohammad Samani

I installed gedit-latex-plugin successfully. I also installed rubber
sudo apt update
sudo apt install rubber

But when I try to build a pdf file from a tex file, I see this error message:

Traceback (most recent call last):
  File "/usr/bin/rubber", line 5, in <module>
    from rubber.cmdline import Build, Clean
ModuleNotFoundError: No module named 'rubber'

Calling rubber from the command prompt has the same effect.
I am running
Ubuntu 18.04.6 LTS.
gedit 3.28.1
LaTeX Plugin 3.20.0

Which python version do you have defined as your default?

For diagnostic purposes, what is the output of the following commands:

uname -a
lsb_release -crid
python --version
apt policy rubber
ls -ld /usr/lib/python2.7/dist-packages/rubb*
ls -l /usr/lib/python2.7/dist-packages/rubber/cm*

Rubber version 1.4-2 as configured for Ubuntu 18.04 is working only with python 2.7
You have to reconfigure your system such that the "python" command starts python2.7
