Hello everybody!  
I use Dolibarr 17.0.2 on Windows 10 and Chrome.  
Today I tried to install verison 18.0.3 an I got the attached message. Can anybody help please. I must work this weekend. I have a backup copy.  
Should I continue and ignore the errors or just reinstall version 17.0.2?  
Thank you for helping

What if you upgraded  
17.0.2 → 17.0.3  
17.0.3 → 18.0.0  
18.0.0 → 18.0.1  
18.0.1 → 18.0.2  
18.0.2 → 18.0.3

Thanks for your answer.  
Sadly I tried to upgrade directly from 17.0.2 to 18.0.3.  
Is there a possibility do downgrade again to 17.0.2?

if the upgrade failed as your picture indicates, wouldn’t you still be running the old version?

And if not, what about your backup?

This Looks like an issue on your llx\_product\_stock table fk\_product column being the reference of llx\_product (row\_id column).

i suggest you check your llx\_product\_stock table id you have duplicate fk\_product.  
 → select fk\_product, count(1) from llx\_product\_stock having count(1) \>1;

Hello everyone!  
Thank you for your answers.  
Finally I had to uninstall Dolibarr, install a fresh copy and restore the backup.  
Everything is OK now
