[Bug 1890197] Re: mediawiki schema issue after do-release-upgrade -d from 18.04 to 20.04

[Brian Murray]

I'm not familiar with mediawiki but there is a file named update.php
provided by the package.

(focal-amd64)root at impulse:/home/bdmurray# dpkg -L mediawiki | grep -i update.php
/usr/share/mediawiki/extensions-core/Gadgets/includes/content/GadgetDefinitionDeletionUpdate.php

Title:
   mediawiki schema issue after do-release-upgrade -d from 18.04 to
  20.04

Status in mediawiki package in Ubuntu:
  New

Bug description:
  Hi,

  I needed to upgrade the server where my mediawiki runs to to get
  unison working from our laptops to it.  Therefore I ran 'do-release-
  upgrade -d' to upgrade to focal - I've already done so for a couple of
  other things including my laptops where this worked well.

  But, the mediawiki database schema was not upgraded afterwards causing
  error on login.  The interweb suggests running Update.php - but this
  does not seem to be included in the mediawiki package.

  $ dpkg -l mediawiki
