[yocto] eSDK install script failure

[Andrea Galbusera]

Seeing the errors below while installing an eSDK. This is a routinely
generated VM that installs the eSDK from installation script. The errors
appeared with the latest iteration of the eSDK script, which is generated
with almost up-to-date revisions from master. Of course I have extra layers
in the mix, but none of them apparently had relevant changed since last
(working) iteration: mostly synching to master branches happened. Can
anyone help suggesting how to investigate this further? What do those
unexpected task mean? I'm blocked on releasing this SDK to developers and
clues from expert would be very appreciated...
