Solved Differences sql from beta to rc

Checking the beta code with the latest rc, I noticed that the migrated items are missing and the updates no longer contain the files relating to version 5? It may be that such installation problems are due to the sql not finding the correct files and giving them as output

duplicate key?

Hello,

Actually the rc1 is the developpement version of RC1 (which was renammed from beta8 developpement version). Kunena 6.0 take care of upgrade from previous kunena version from 5.1 not older versions

From which Kunena version did-you have tried the upgrade ?

The version is 5.2.8. As I perform the update I get an error message which is the following:

JInstaller: :Install: Error SQL Duplicate entry '1' for key 'kslt6_kunena_groups'
JInstaller: :Install: Error SQL Duplicate key name 'mesid'

I tried to install the latest version but the error it reports is the same.
The version of 02-02-2022 works perfectly.
 
Among other things, with the beta 7 and the RC1 of 2-2-2022 I have not encountered any problems.

I also added the error to the following ticket [K.6.0] Update support

I am also testing the builds by compiling them from github but the result is the same

I solved the problem using the latest build of github by compiling it.

Basically I made a backup of the kunena tables and then I always made an upgrade to the tables using the sql
