    To be doubly sure what you are currently running let's see the output of command
    Code:
    lsb_release -a

    Appears you have a 50% 18.04 system and a 50% 20.04 system.
    Something isn't right.

    I'd pave the road and start fresh. "I say we take off and nuke the entire site from orbit. It's the only way to be sure.”

    Hmm!
    Not sure that's correct. The active lines in your sources are all for focal and all the bionic lines and repos are commented out so I'm really baffled.
    However, a new clean start may solve your problems.

    I've never upgraded from version to version of my systems so can not really help much more with potential difficulties of version upgrades.

    I could be confusing Heeter's system with another post here that was all 18.04 the last 7 days.

    I've upgraded a KVM host from 10.04 --> 12.04 --> 16.04 --> 18.04 without many issues. Newer KVM/libvirt machine types still support the older machine types. That host has been losing VMs the last 2+ yrs, since newer hardware on another system is 10x faster and has 2x more RAM. That other system was loaded with 18.04 and is still running it. For example, so systems:
    Code:
    <type arch='x86_64' machine='pc-i440fx-trusty'>hvm</type>
    <type arch='x86_64' machine='pc-i440fx-xenial'>hvm</type>
    <type arch='x86_64' machine='pc-i440fx-xenial'>hvm</type>
    <type arch='x86_64' machine='pc-i440fx-trusty'>hvm</type>
    <type arch='x86_64' machine='pc-i440fx-trusty'>hvm</type>
    <type arch='x86_64' machine='pc-i440fx-xenial'>hvm</type>
    <type arch='x86_64' machine='pc-1.0'>hvm</type>
    <type arch='x86_64' machine='pc-i440fx-xenial'>hvm</type>
    <type arch='x86_64' machine='pc-i440fx-xenial'>hvm</type>
    The pc-1.0 is actually a Xen VM which I migrated from 2008 Xen to KVM in 2010-ish.
    Oddly, I don't have any newer VMs, since I cleaned up all the play VMs for 21.04 a few days ago.

    Hummmmm. There's a bug: https://bugs.launchpad.net/ubuntu/+s...t/+bug/1902654
    There is some information in the bug about keyboards and console types when a VM is migrated to pc-i440fx-wily .... hummmmmm.
    Basically, VMs don't like when the hypervisor goes from 18.04 --> 20.04 or later.

    Re: Can I track down and reverse certain recent updates?

    Hey Guys,

    Cannot thank you enough for all your input. I really do appreciate for all your quick responses. Means a lot right now, as I don't have too much time to get the mailserver running.

    Is there someway that I can try to just upgrade to 20LTS from this?

    Just need to get the VMs backup for a couple of days until I can make a plan on fresh install. Need to anyways, the LVM partitioning on this setup needs to be rethought out too.

    Regards

    be sure to read the bug in my last post. 20.04 could make you have to create a new VM and reload the OS for the mailserver. No upgrade.

    Thank you Fu. Ugh, I misread the bug. I thought that by upgrading, that It would fix it. Good thing that you mentioned that.





    If any of you can assist me directly, please pm me,

    From the terminal output you showed us
    Code:
    root@serv:/home/adminpc# lsb_release -a
    No LSB modules are available.
    Distributor ID:	Ubuntu
    Description:	Ubuntu 20.04.3 LTS
    Release:	20.04
    Codename:	focal
    it appears that you are already using 20.04, the latest LTS version available, so your inability to boot the VMs is not related to that, unless it is a symptom of moving from 18.04 to 20.04 at some point in the past.
    Do you know when you upgraded, or is that all hidden in a mysterious past that you can't remember?
