Still some mess-up with rights I guess, from the log looks like it is being executed as user Volumio not with sudo rights.:
Executing corechooser.py...
Error executing corechooser.py: Command failed: /usr/bin/python /data/plugins/user_interface/smartqueue/unit/corechooser.py
kill: (1266): Operation not permitted
mmm, Iāve not changed the nodejs exec command for a whileā¦
ā¦but I moved install.sh āapt-get commandā to sudo recently, it may have break python ā¦ 
Please test this on a clean install of Volumio to be sure it works, before handing over. As this takes much time to test and debug.
My testing protocol on each machine (for v 1.1.1)
What more can I do solo ? I need other users like you to go forward Iām afraid
Iāll do my best to improve my protocol but thereās a price to pay for this unbeatable plugin (for music lover) 
No idea, but here I can get it started on the Motivo by saving the settings, but the rpi is just failing. Only when I execute the corechooser.py as sudo manually.
I donāt mind spending these hours (8-9 hours per test) , but if the very basics fails its not motivating.
Yes I understand and in addition you take already a great part of the mental charge on this forum to help everyone, this is huge , for yearsā¦
Thx a lot
Are all your test machine moved to latest beta ? maybe need to add this option to my protocolā¦
I always update to the latest beta, part of testing for Volumio 
One thing that could make difference between you and me :
Did you factory reset your device before installing v 1.1.1 like me ?
version of my plugin before 1.1.0 installed request via pip, and Iāve proved that āpip install requestā broke volumio
Pip and requests was not part of my uninstall procedure upon Balbuze request because python part could be used by other plugin or volumio
Now iām installing requests via native āpython-requestsā package (Why the hell didnāt I do that at first instance !?!) BUT, if you donāt have factory reset your device, pip and maybe all requests stuffs are still present on your machine so could have a bad influence
If you could answer this question (before any further test) it could be very helpfull for my dev path
I havenāt done a factory reset on the 2nd run as it Will take me to much time to scan the library again.
Maybe next week I can give it a go.
Any reason to stick with the outdated version of Python instead of Python3?
Another good question ā¦ matter of habit, Iām not as much expert and donāt even know why python and python3 still coexist in modern linux distribution
Do you have any advise/experience on this subject for me ?
I think the only reason is to support older coding.
But everything new should be preferred in Python3.
version 1.1.3 add
- switch to python 3 (no more reboot nor scan issue)
- translation fix
- remove sudo from install apt command
Tested successfully on fresh beta on primo and rpi3
@volumio
I believe itās ready - at least for beta - and I would appreciate this move forward to enlarge my testing base
Patience.
Need to run a trouble free run first, then the impact needs to reviewed (need to be sure it wonāt break anything). Then it will be ready to move into the Beta channel.
Almost there.
Tested on a rPi4, after factory reset.
Installation went fine and pretty fast, settings are remembered.
However after every restart you need to got into the settings and hit āsaveā in order to have the plugin work.
@balbuze any idea how to solve this, as itās very unpractical
I canāt test because Iām away, but it could be due to the fact that config.json is copied and permissions set by install.sh. Itās not required in a plugin.
@chourmovs_vs we spoke about this on GitHub
Hi Balbuze, this is no more the case since version 1.1.0, I addressed any of your remarks so far
At the beginning this was an unwanted situation, but I didnāt work on it because I found it pratical to have to āstartā the engine. Indeed you are right (again) , There is already the on/off plugin section button, I need to fix this maybe this evening and this should not be the trickiest part.
Iāve ran it for a couple of runs now (using bliss), but the repeating songsā¦

Ok, Weāre starting to talk about the substance 
, it smells good
Based on my tests, There are two techniques to avoid repetitions
with lastfm : using drift parameter > 0
with bliss : increase number of tracks (10 for example) and / or drift
iām going to provide an how-to
what part of your library has been bliss analyzed ?
Iāve removed drift from bliss.py for simplification.
Iāve never had this repetition level with 10 tracks queue but itās understandable that with similarity metrics āgravity holeā could occur in certain circonstance
It will also depend of your seeding song.
Maybe try to extend tracks # to 15 as test.
On last resort, Iāll modify the āvolumio api postā logic to avoid repetition
