Linux1,3,4,5 rebuilt with Ubuntu 20.04

  1. Linux2 is available for use right now.
  2. linux1,2,3 are now available.
  3. linux4,5 are now available.
  4. All servers are back in the linux.cs round robin.

vdesk service is rebuilt

I expect the service to stay up, mostly. Nodes will be going up and down depending on when they get rebuilt so expect disconnections if you HAVE to use this service.
