Duplicati versions install mess up!

That is a mess up, due to a check in the code that was not triggered during testing.
The update is in a transition state that was designed to be smoother, but ultimately got a bit messy if you are not already on 2.0.8.1.

I can see that this is a bit confusing, but as @ts678 mentions, this only happens because you do not have a password set, and this is now required. The dialog was designed for new installations, but pops up on upgrades, so perhaps the wording should have been a bit clearer.

Hope you get it working despite the trouble.

Sadly no :cry:

The manifest serves both the users of 2.0.8.1 (for whom it is working) and older installs where it does not work. At this point I only have the option of breaking 2.0.8.1 upgrade notices or the current state. At least in the current state you are alerted that there is an upgrade.
