Hi, I’m currently trying to install tryton-server, on a distant machine still without success, and following this as a guide: [http://blog.accendero.com/open-source-erp-solutions-part-four-tryton/](http://blog.accendero.com/open-source-erp-solutions-part-four-tryton/) I had few errors during the install process, I list them below for information: **1) when trying to install the database:** ``` root@sda-tryton:/var/www# sudo trytond-admin -c /etc/tryton/trytond.conf -d tryton --all 3178 139789022312256 [2020-09-18 14:07:02,489] ERROR trytond.convert Error while parsing xml file: In tag record model ir.lang with id ir.lang_bg. ``` Which I solved creating a database with UTF-8 encoding: `CREATE DATABASE tryton WITH OWNER = postgres ENCODING = 'UTF8' TEMPLATE template0;` Tell me if this is not recommended. **2) with sao client install** ``` git clone https://github.com/tryton/sao.git npm install --production npx bower install --allow-root ``` Grunt give an error complaining about a missing library `grunt-po2json` which I solved using `npm install grunt-po2json`. Now grunt still fail: ``` Running "default" task Running "concat:dist" (concat) task Running "jshint:dist" (jshint) task >> 1 file lint free. Running "jshint:grunt" (jshint) task >> 1 file lint free. Running "jshint:tests" (jshint) task >> 1 file lint free. Running "uglify:dist" (uglify) task >> 1 file created 967.86 kB → 424.73 kB Running "less:dev" (less) task >> 1 stylesheet created.

Ok I’ve switched to branch 5.0, and install is successful. But maybe this should be documented somewhere. What about the database encoding problem? ---

Can you help? I stumbled over the same issue and could solve it by adapting Gruntfile.js ``` diff --git a/Gruntfile.js b/Gruntfile.js --- a/Gruntfile.js +++ b/Gruntfile.js @@ -113,19 +113,20 @@ module.exports = function(grunt) { 'dist/<%= pkg.name %>.css': 'src/sao.less' } }, 'default': { options: { paths: [ 'src', 'bower_components', + 'bower_components/bootstrap', 'bower_components/bootstrap/less', 'bower_components/bootstrap-rtl-ondemand/less', - 'bower_components/eonasdan-bootstrap-datetimepicker/src/less', + 'bower_components/tempusdominus-bootstrap-3/src/less', ], yuicompress: true }, files: { 'dist/<%= pkg.name %>.min.css': 'src/sao.less' } } }, ``` But I did not yet find time to dig into why I needed to change this. ---

So you should update the sao version to match the first two digits (series) of your trytond server. You can know your server version with: `trytond --version` Before building sao you should checkout the compatible branch. So if your tryton version is `5.0.21` you should checkout the `5.0` branch of sao before building it.
