Run the provision script on a virtual machine with ubuntu 20.04, using the ubuntu-dev repo. It passes OK because ubuntu 20.04 ships systemd v45, which still uses cgroupsv1:
$ dpkg -l |grep systemd
...
ii systemd 245.4-4ubuntu3.4
$ cat /sys/fs/cgroup/cgroup.controllers
cat: /sys/fs/cgroup/cgroup.controllers: No such file or directory
and running the hasher workflow passes.
To verify with newer systemd, I updated ubuntu's systemd package to 247.1-4ubuntu1, rebooted the instance and I found that it's still using cgroups v1.
Searching around, it seems that, due to some regressions, Ubuntu reverts Debian's systemd changes and they will ship cgroups v1 until 21.10.
So I'd say Arvados will be OK in ubuntu 20.04.
