After installing latest updates to LL 3.x almost no application launches anymore

[ealgiros]

It happened twice:

1) first when the computer had LL 3.4 and installed the latest updates.

2) Second, it started to happen after installing the latest updates for a new installation of LL 3.8 (on the same computer)

• I installed LL 3.8 from scratch (all fine)
  But, after I installed the latest updates... most of the applications stopped launching anymore.(even LL 'Install Updates')
  So, I searched the web and found the following solution: run from terminal
  

Code:

sudo apt remove virtualbox-guest*
