Description
I was trying to downgrade a 5.4-milestone1 installation from the 'releases' repo to 5.3 from the 'stable' repo. So after uninstalling the 5.4 packages, and installing the 5.3 packages (keeping configs and DB), i got as far as the distribution wizard. When trying to downgrade the UI via the downgrade button, i end up with an error, this is the entire output:

I could resolve the issue by skipping the distribution wizard, going into the extension manager and removing the main UI extension (XWiki Enterprise - UI) along with most other 5.4 extensions (except for admin/extension management). I then restarted the distribution wizard, which installed a fresh 5.3 UI (went through some diffs -> replace) and downgraded/replaced leftover 5.4 extensions.
