[Bkchem-user] install bkchem 0.14.0-pre4 Ubuntu 22.04 LTS

[FyD]

Dear all,

To install 'bkchem 0.14.0-pre4' on Ubuntu 22.04 LTS with (with by  
default python3):

sudo apt install bkchem
sudo apt install python2
sudo sed -i 's|exec python3|exec python2|' /usr/bin/bkchem

I run bkchem on Ubuntu 22.04 LTS and get the following error messages:
bkchem
Could not load module pdf_cairo
Could not load module png_cairo
Could not load module svg_cairo
Could not load module ps_cairo

On Ubuntu 18.04 LTS; no problem I can find the 'python-cairo' package:
sudo apt install python-cairo
...
python-cairo is already the newest version (1.16.2-1).

Is there a 'python-cairo' package for Ubuntu 22.04 LTS to be used with  
python2 ?
I cannot find it...

thank you,
regards, Francois
