xTuple Updater 2.5.4 is now available for download from the xTuple Customer Portal. This release fixes a bug in Updater 2.5.3 that prevented errors from being reported correctly. This version will be required for xTuple ERP 6.1.0.
I am not seeing the Updater packages when logged in on the Customer Portal. Have looked under the individual xTuple commercial releases.
When logged in to the Customer Portal, be sure to click on the “Updater” option on the downloads list. It is separate from the xTuple downloads (screenshot below). If “Updater” is not on the list of packages you can download, you may need to reach out to your Customer Success Manager (CSM). Hope that helps.
