I see you marked the thread solved -- I assume you figured it was the PPAs ?? 

[newtusmaximus]

firenice03, thanks for responding.  Yes it would appear that PPAs that had historically not been causing problems, were now interfering .  Temporarily isolated them and update was smooth.  Then upgraded to 3.8 and updated again , still with PPAs unticked.    Will look into why the  PPAs are now taboo - online user forums etc.
Will jump to LL5.0 on this machine when support for 3.8 ceases (April 2021)  HP desktop.
