Unable to upgrade MAHARA 20.10 to 21.x

[james william]

Hi,

I have a old installation of Mahara 20.10.1 which I wanted to upgrade to the latest one i.e 21.04.0
However I am facing the following error while upgrading.

My Mahara Site: Site unavailable
Database version of Mahara plugin saml 1.9.0 (2021021701) is newer than files version 1.9.0 (2021021700). Please make sure you have the correct Mahara plugin files in place.

I think this is happening because the latest version of Mahara contains old version of "saml" plugin (2021021700) and my old version of Mahara contains newer version of saml plugin (2021021701)

I have not installed this plugin manually it came with Mahara 20.10.1 package itself.

Can anyone let me know how to solve this ?

The easiest way to solve this for your site is to update your database and set the value to be the older one

UPDATE auth_installed SET version = '2021021700' WHERE name = 'saml';

It will run through that bit of upgrade again which should be safe to do

Cheers
Robert
