Hello,  
I’m running the usual line to install dolfinx on a Colab notebook:

```auto
try:
    import dolfinx
except ImportError:
    !wget "https://fem-on-colab.github.io/releases/fenicsx-install-real.sh" -O "/tmp/fenicsx-install.sh" && bash "/tmp/fenicsx-install.sh"
    import dolfinx

```

and getting the following error:

```auto
---------------------------------------------------------------------------
ModuleNotFoundError Traceback (most recent call last)
<ipython-input-1-8cc2a7230184> in <module>
      1 try:
----> 2 import dolfinx
      3 except ImportError:

ModuleNotFoundError: No module named 'dolfinx'

During handling of the above exception, another exception occurred:

ModuleNotFoundError Traceback (most recent call last)
<ipython-input-1-8cc2a7230184> in <module>
      3 except ImportError:
      4 get_ipython().system('wget "https://fem-on-colab.github.io/releases/fenicsx-install-real.sh" -O "/tmp/fenicsx-install.sh" && bash "/tmp/fenicsx-install.sh"')
----> 5 import dolfinx

ModuleNotFoundError: No module named 'dolfinx'

---------------------------------------------------------------------------

```

Is there an open issue about this?

Thanks!

Probably due to this:

> <https://github.com/fem-on-colab/fem-on-colab/issues/15>
>
> Google Colab was upgraded to use python3.8, see
> https://github.com/googlecolab/…backend-info/commit/c43ed71620aa951a5747d40324f1831f0d5e4d84
> 
> This has broken all of our packages, which were built for python3.7. Upgrade is currently in progress.
