Hi there
I try to upgrade from Ubuntu 20.04.6 LTS to 22.04.2 LTS and Koha from 20.05.18 to 23.05
Somehow all looks good during the upgrade, but at the end I am landing at a webpage with:
Welcome to the Koha 23.05 web installer
Before we begin, please verify you have the correct credentials to continue.
Please log in with the username and password given to you by your systems administrator and located in your koha-conf. xm1 configuration file.
Please enter your username and password
But no known account works...
Any hint, what's wrong?
