@Bolder You are correct, manual update states incorrect details that are miss leading. I’ve updated the docs and they should be published shortly to now properly reflect the manual update and also the offline update process.
For those behind Proxy, you can follow the https://docs.multiportal.io/kb/article/0000050/.
Just a heads up, at this stage if you have used the offline-update, there is no method currently to update the installation via the automatic process.
