Near as I remember I installed 4.2 via sickly life ppa as that was the 
only way I could.  4.8 was via Flathub.  Per your recommendations I am 
going to try to uninstall both versions, if I can.

As far as building from source, I found the documentation links to be 
woefully outdated for version 4.9.  I would like to build in the /opt 
directory so is available to all users.

I vaguely remember a post about not pulling source from, I want to say 
git-hub.

And due to having a power supply in my server literally exploding at my 
feet while the server was up, there was a hiccup in Ubuntu causing the 
loss of a few files. My desktop links were among them.  I think I 
managed to recover/restore everything else (recommendations on backup 
software would be welcome as well).  If you've never had a power supply 
explode while you are sitting next to it, then you are in for one 
adrenaline pumping experience. Thankfully it did not seem to do any 
damage to the motherboard (fingers still crossed and knocking on wood).
