20.04.1, when applying updates, 'full log' is reporting for every package install: E: Can not write log (Is /dev/pts mounted?) - posix_openpt (19: No such device)

https://askubuntu.com/questions/1490233/what-is-curtin-command-in-target-and-why-does-it-take-so-long-to-run

I frequently install Ubuntu on VMs running under Proxmox or VMware. Every time the installer gets to curtin command in-target and stays there for at least half an hour, sometimes much longer. The Ubuntu installer at this point gives an option to "Cancel update and reboot", but if that is chosen it then sits unchanging for about the same time that just leaving it to complete does.
