I am going to drop this from the 24.04.1 milestone. I don't see a
straight forward way that someone would get in this situation by using
supported upgrade mechanisms. E.g., I tried:

$ lxc launch ubuntu:bionic bionic
$ lxc exec bionic bash
# cat > /etc/apt/apt.conf.d/no-recommends.conf << EOF
APT::Install-Recommends "false";
APT::Install-Suggests "false";
EOF
# do-release-upgrade

After upgrading to focal, usrmerge is not installed. Okay. Now upgrade
to Jammy:

# do-release-upgrade

After that, usrmerge is installed during the upgrade despite the no-
recommends.conf being in place:

# cat /etc/os-release

Not saying this cannot be SRU'd still in the future, but it does not
seem common enough to be prioritized for 24.04.1.

Bug description:
  [Analysis]
  usrmerge was not essential on 22.04 and systems that upgraded to it may not have been converted, as it was only Recommended.

  We need to add quirks to ubuntu-release-upgrader to convert systems
  that are not yet merged by first installing the usrmerge package.

  [Original bug report]
  Doing upgrade from 22.04 -> 24.04 beta.
