Title:
  Upgrade from 20.04 to 22.04 failed

Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  On focal 20.04  I executed the following commands:

  sudo apt-get update
  sudo apt-get upgrade -y
  sudo apt-get install update-manager-core -y
  sudo apt-get dist-upgrade -y
  sudo apt-get autoremove

  also I disabled 3rd party repositories (Google, FreeCad and some other) 
   in /etc/apt/sources.list.d/ 

  Checking the version I have
  uname -mrs
    > Linux 5.13.0-40-generic x86_64
  lsb_release -a
    >   No LSB modules are available.
         Distributor ID:    Ubuntu
         Description:    Ubuntu 20.04.4 LTS
         Release:    20.04
         Codename:    focal

  Then I run the following command to execute the distribution upgrade
  procedure

  sudo do-release-upgrade -d

    And deep down into the process  (95%)  I hit the following "bug" 
  ...
  Installing new version of config file /etc/xdg/autostart/org.gnome.Evolution-alarm-notify.desktop ...
  Processing triggers for dbus (1.12.20-2ubuntu4) ...
  Processing triggers for libc-bin (2.35-0ubuntu3) ...
  Reading package lists... Done    
  Building dependency tree

     I have to admit of this is really a but or if it is "self-made"
  that I broke the python installation myself as I see that is using
  python38 from my system.

    I haven' t rebooted the computer ... The computer is "functional" but many Apps (file browser, LibreOffice to mention 2) have disappeared. I am scared that if I reboot I am going to be left without notebook to work with.
    Any guidance to get out of this issue would be much appreciated. 

  Thank you for reading.
