Trident questions


I’ve succeded to upgrade my Trueos Desktop 18.03 to Trident 18.12U1 by installing in a new BE and recreating users. This work well and I have now to install other apps.
I have 2 questions:

  1. Where can I find the max number of BE in Trident
  2. To upgrade to U2 or future versions, what is the right way:
    • trueos-update in a terminal
    • Update Manager in Desktop Settings
      And Many thanks for your works to make Trident alive


1: no automatic way, yet

2: sudo sysup -check
sudo sysup -update
