[Bug 1898614] Re: ubuntu server installer serial console not preserved after update

[Michael Richardson]

Hi. I got KVM+serial console to work this time.  (I think that by default, kvm doesn't give the installer enough ram).  Going through my proceedure, I allow the installer to upgrade, and it does in fact continue on the serial console.  It also continues on the tty0, so perhaps I was confused by this.  
Sorry for the false report.

  ubuntu server installer serial console not preserved after update

Bug description:
  I booted ubuntu 20.04.1 from a USB key to install a server.
  (It would be great if that was a regular option, and if grub could be more easily tuned to include console ttyS1)
  Ubuntu nicely discovered that I had booted from serial console, and I opted to stay with the non-rich mode, since I was using an xterm and serial console (SOL) via IPMI.
  I agreed to update my installer.  Then I lost everything.
  It seems that the installer was then running on the tty0.
