Hi everyone,

Nice to hear from BKchem partners.
I have been the BKchem translator of Taiwanese Mandarin since 2007 (when I was a PhD student).
My background is in agricultural chemistry and food science. I do not know how to program. However, I can help test if a new version of BKchem is available.

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:
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
