Hello,
I am trying to start a Tryton 7.2.1 deployment from scratch on Gentoo. When trying to add GBP currency I get this error:
Ctype of the database in PostgreSQL is en_GB.UTF8
Probably in your config file you have defined the default language as en_GB which was valid from older versions but for newer versions must be updated to en
You must fix your config file and recreate the database to fix the problem.
