After Ubuntu upgrade - AttributeError: 'module' object has no attribute '_set_dut_singleton'

[Andrew Liverod]

Hi

I've just upgraded from Ubuntu 14.04 to 16.04 and then 18.04 and had the following error when running stbt (v28). It and my scripts worked fine with 14.04 but fail with either 16.04 or 18.04:

I've tried stbt with a really simple script as well:

  while (True):
    pass

and then:

  # stbt run --control=lirc::amino-h150 test.py

Same problem.

Presumably you have a different (older) copy of stbt somewhere on your import path, and stbt-run is importing that instead of the v28 version.

Kind regards,

Hi David

You were right. Something went wrong when I last updated. I removed the stb-tester package, checked /usr/lib and there was still a load of *.pyc files in there. Removed the files, re-installed stb-tester and it's now working fine.

Thanks for your help

Andrew
