Missing iplayer dependency

Hello!

I tried installing iPlayer www addon (v3.0.0) in Krypton (running on Linux Ubuntu).
It’s a fresh kodi installation.

The install always fails, the log says:

Code:
13:55:37.771 T:139930283894528   ERROR: CAddonInstallJob[plugin.video.iplayerwww]: The dependency on inputstream.adaptive version 1.0.6 could not be satisfied.

I downloaded this plugin from git: https://github.com/peak3d/inputstream.adaptive
but when I attempt to install this from the zip file, the log states:

Code:
14:04:48.201 T:139931607111680   ERROR: Failed to read 'zip://%2fhome%2fstef%2fDownloads%2finputstream.adaptive-master.zip/inputstream.adaptive-master/addon.xml'

Looking in the unzipped file, I do not see an ‘addon.xml’, also it looks full of C++ sources which I guess need compiling. Speculation creeping in here …

Any hints as to what I may be doing wrong please??

cheers,
Fred
