Hi unix,

I installed a few Unipi 1.1 and UniPi Lite 1.1's. A few days ago I want to install a new one (raspbian + evok), And I have the same problem. I tried to remove and re-install the Evok, it did not help. I re-installed everything (OS + evok), same result. You are not the only one with this problem.
I hope there is solution soon....

@unix, @Bart-Delaere

Reposting from the other thread, the Master branch is currently buggy:

It looks like the latest master commit on EVOK has a bug in that regard. We've recently added functionality to query the version of EVOK via the API, but it looks like it might be buggy.

I recommend downloading a stable release by following the instructions on the [GitHub page](https://github.com/UniPiTechnology/evok) instead. I will fix the issue on the master branch today.

It should be fixed today within a few hours.

@unix
The issue should now be fixed both in Master and in the latest release. v.2.0.5f

As a side note you can now query the version of your EVOK via /version/, though unfortunately it only applies from v.2.0.5f onwards.
