The OP said this was used:

However your version is 3.5,2.

Try bench migrate-env python3.5.2 or see if you can install python 3.6 .

What is the host environment, OS etc?

9

OS: Ubuntu 16.06, 2GB, 2 Cores.

Try bench migrate-env python3.5.2 then bench update --reset

11

I had problems using Ubuntu 16. The stable version for ERPNext is Ubuntu 18

12

@Joseph_Marie_Alba1 How did you successfully migrate ERPnext to Ubuntu 18?

Did you created a new instance and moved the db on it or what ?

13

Yes. backup the database using bench backup (search this forum)
then, restore to the new setup using bench restore (search this forum)
