Ubuntu: coherence missing after upgrate

After upgrading the system to 16.04.4 (sudo apt-get update; ... upgrade; ...dist-upgrade) and reinstalling Parallels Tools, Ubuntu works well but Coherence doesn't works, it is greyed and I cannot succeed to activate it.
Any help, please?

Thanks in advance

Hi @salvomic , please follow the steps suggested in the article and check if that works.

 

ok, I'll try it.

 

tried it just now: no luck, it doesn't work here. Beside, Mac OS X 10.13 hasn't a "repair permission" utility...

 

Hi @salvomic, please send a technical data report via Help menu > Send Technical Data...
PLease post the report ID here.

 

ok! thank you!

EDIT:
I sent the report. The ID is # 257757641

 

Thank you very much! Can you please try to Log Out from user session, log in back and check if 'Enter Coherence'' option is available?

 

Done. Still greyed and still the message "to use coherence you may need to log out"

 

Got it! Our Engineering Team had identified the issue and working on the fix.

 

Well, thank you! I'm looking forward for the solution...

 

We are glad that you are able to enter coherence view after updating Parallels Desktop to version 13.3.1. Let us know if you have any questions.
