Very Slow Start-Up (Virtualbox already purged)

[CoffeeBean]

My observation is first, you have a very slow HDD to blame. I suggest you check first with this command in the Terminal:

Code:

systemd-analyze critical-chain

I would also look into some start-up processes such as apt-daily, nmbd, network -xxx-xxxx-online, motd, modem manager, accounts daemon, to consider disabling or masking if you don't use them at all.
       
     

I disabled the apt-daily related services and timers and that helped a lot.  Thanks.
