Dear All,

On Ubuntu 18.04 LTS:
cd /usr/lib/python2.7/dist-packages
sudo tar zcvf cairo.tgz cairo

On Ubuntu 22.04 LTS:
cd /usr/lib/python2.7/dist-packages
sudo tar zxvf cairo.tgz

-> I get cairo on 22.04 LTS and it looks like one can do some stuffs with that...
dirty work I guess ;-)

regards, Francois

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
