Comment 15 for bug 1967139

I've confirmed that the dashboard does deploy correctly on Jammy with this update enabled:

# apt-cache policy python3-cheroot
python3-cheroot:
  Installed: 8.5.2+ds1-1ubuntu3.1
  Candidate: 8.5.2+ds1-1ubuntu3.1
  Version table:
 *** 8.5.2+ds1-1ubuntu3.1 500
        500 http://archive.ubuntu.com/ubuntu jammy-proposed/main amd64 Packages
        100 /var/lib/dpkg/status
     8.5.2+ds1-1ubuntu3 500
        500 http://nova.clouds.archive.ubuntu.com/ubuntu jammy/main amd64 Packages

Looking at the autopkgtest failures, it looks like it may have been from the testbed being out of date
