Dear all,

On a Ubuntu 20.04, documentation builds stops with

Hi Vincent,

I did not had such an issue on my Ubuntu 20.04 computer. Your log says

'cremona_mini.db' not found in any of ['/home/debian/sage/local/share/cremona']

For some reason, this file is present in my sage root directory but not in yours:

ls -l /home/eric/sage/9.6-develop/local/share/cremona
total 8200
-rw-r--r-- 1 eric eric 8392704 févr.  8 14:34 cremona_mini.db

Best regards,

Eric.
